There comes a point where the leading edge of the blade begins shutting off area to the blade behind it. Solas propeller application chart. However, they are not to be credited with the origination of the technology. The amount of horsepower is figured in with the weight, peak rpm level, and many other factors. This results in a collective action that increases the VELOCITY of the water exiting the blade. It may not display this or other websites correctly. Sea Doo Impeller Cross reference chart. You may also decide to add more horsepower, if so, you will get to a point when that great impeller is simply not aggressive enough to provide the added performance to match the new power. Their ads reference "backlash from over-lapping blades". For instance, comparing the stock impeller's pitch to a performance design from Skat-Trak to gauge the aggressiveness of the impeller would be an inaccurate reference. The bottom line is, if you normally carry more or less weight than the craft was designed for, Impros can probably help. They do not represent your craft's potential performance at acceleration and top speed, but is simply the pitch progression of the outer blade angle. Most of the other ones give you more top end or mid range. Impros is a Personal Watercraft Impeller Repair and modification service. The relationship between the impeller and pump exit nozzle diameter is also critical to the performance of the watercraft. The SOLAS product line includes Dynafly impellers for the Kawasaki Ultra 150 pump and the Sea Doo 951 pump. Laminar separation results in cavitation, or the separation of air from water. Here are some of those areas... 1.The pressure differential between the area located immediately in front of and directly behind the leading edge of every blade at the root. To further enhance velocity, water passes through the venturi before finally exiting the pump as thrust. The pitch of an impeller can be deceiving, because of the many geometric differences in impeller designs, even from one manufacture, there is no correlation in pitch between various impeller models. SOLAS Impellers are constructed of high-strength, stainless steel, and feature a polished hub and exclusive hub-end water seal for reduced cavitation. Although water is not compressable, this system somewhat emulates compression. COMPOSITES: You probably never heard of this one. 2.Controlling hydraulics where the outside edge of the blades meet the inner liner wall. Larger pitch decreases acceleration, but increases top speed. There are very few options available to you in this industry for this type of specialized service, Call Us +(951) 737-2900Fax +(951) 737-2900, Website Designed by www.overnightgrafix.com 909-477-0620. When watercraft and impeller manufactures design an impeller, their goal is to reach the absolute best overall performance and efficiency possible for the range of PWC pumps that the impeller applies to, and provide you with both bottom-end and top speed without having to compromise. KICKS: Once water begins acceleration from the leading edge to the trailing edge, it can be catapulted (nominally) to increase velocity. Sea-Doo Impellers; Sea-Doo Impellers. However, due to the spiraling effect (vortex) of water leaving the trailing edge of the blade it must pass through stators (straightening vanes) to "true" its trajectory. Using the impeller that was designed for sea level performance restricts the motor, because the lack of oxygen to your engine will not allow it to run at it's peak performance combined with the sea level impeller. Many of the designs have good technical merit but in actual application, do not work as effectively as theorized. Laminar separation results in cavitation, or the separation of air from water. All "R" model Solas impellers are placed in a pitch-block before leaving Solas to ensure accuracy for optimal performance. I stock many new and used impellers ⦠Isn't that ski a 951? http://impros.com/charts/skat_seadoo.html, http://impros.com/store/index.php/tech-info/about-impellers.html, 95 GTX Gauge Issues - Speedometer & Multifunction, cryptoasic.com world delivery miners company. With a varying amount of riders and cargo, the weight being carried on some craft can fluctuate to more than 500 pounds. Sea Doo Impeller Reference Chart. At the same time, a smaller pitched leading edge reduces laminar separation due to a lower pitch angle. If you are higher than 4000 feet above sea level, we recommend that you choose 1 pitch combination lower than what the recommendation charts generally list. ; New Solas Sea-Doo 4-Tec Impeller with Impeller Tool & Wear Ring, Solas SR-CD-11/19 - 11/19 Pitch Includes: Solas Impeller SR-CD-11/19 / Impeller ⦠Military research programs developed these materials and we've worked with them extensively.

Pulling a water skier or knee boarder is a good example of when additional low-end thrust is beneficial. At the same time, water must rush in to fill the space left behind the blade. Here is a great article written by Kevin Cameron that also provides a good understanding of the Jet pump's part in moving your watercraft. OVER-LAPPING BLADES: The next big step was over-lapping blades which gave an increased blade area to accelerate water while increasing vacuum, critical to bringing more water up into the gullet and thus producing more thrust. List of available Impellers for Sea-Doo Jet boats and PWCs. Make sure this fits by entering your model number. Solas sd-cd-15/23 Sea Doo impeller is great for pulling skiers to race. Am I getting the following right... impellers of the same design, but different numbers might be described compared to the stock 14-21 as follows: 13-19 less leading edge pitch so less "bite" and less friction, so higher RPM. Lol. 800 S California Ave, Parker, AZ, 85344, Phone 928-669-2549 ... Parker Yamaha Com Home Page > Solas Impeller Chart. The recommended pitch of each specific design is based on the performance traits of that specific impeller model that is found to be most efficient on each craft, with various horsepower ratings in mind.

Free shipping on orders over $100! The wide variety of SOLAS impellers for Sea ⦠Thrust is created by water being drawn into the impeller and accelerated out the back. Solas concord will give you 1 or 2 more MPH, but less pop out of the water, Skat-Trak will give you more pop out of the water but less top end. This concept works much like a catapult. Unfortunately, this design is not conducive to progressive pitch, which is far more valuable. This upgrade over stock Sea Doo Impeller ⦠On the chart below, sometimes you may notice several different part numbers for the same pitch impeller. So be careful when looking at the numbers used for pitch, they can be deceiving. Every craft is a little different, as is the riders' performance desires, you may have a great performing impeller in the craft now, but as stated in the Weight section above, you may want to squeeze every bit of top speed or bottom end out of it. SOLAS Sea Doo 4-Tec Impeller SR-CD-11/19 ⦠Use our SeaDoo impeller buying guide to help choose the correct impeller for your Sea-Doo watercraft.

Jan 16, 2017 #1 Figured this would help some member looking to swap out their prop. The recommended pitch of each specific design is based on the performance traits of that specific impeller model that is found to be most efficient on each craft, with various horsepower ratings in mind. The desired performance with larger craft used for recreation is usually more bottom-end power, which can be achieved by reducing the pitch of the impeller, thus limiting the volume allowed to pass through the pump. Impros is a Personal Watercraft Impeller Repair and modification service. The reason this system works is because it connects three basic principles. We can usually adjust the impeller to accommodate your particular situation. Centrifugal force can activate blade rotation and hydrodynamic pressure can control the angle of attack. If it will be for sale soon, go the cheap route. That is not necessarily the case, when an impeller is designed. (a real no-brainer) What is most valuable about narrow hub designs is the reduction of blow-out at the leading edge of the hub. It is the impact of water against the inner liner wall that substantially reduces the over-all efficiency of current single stage axial-flow pumps. But progressive pitch has limitations when coupled with over-lapping blades! If the leading edge angle is too agressive it creates a paddle effect that "slaps" water as. SOLAS Sea Doo Impeller ST-CD-15/20 951 Limited DI with Wear Ring and Tool. Sea-Doo Impellers for Personal Watercrafts - ⦠For the best experience on our site, be sure to turn on Javascript in your browser. There are many critical things to consider within the design of an impeller that determine the overall load and RPM the watercraft will have. Sometimes we can also squeeze a little speed out of a craft carrying substantially less weight than it was designed to by raising the pitch of the impeller. Please email us with any questions. Stators also increase velocity by "catapulting" water, similar to the way a "kick" works on the trailing edge of a blade. This can accomplished via mechanical means and activated by variables in hydrodynamic pressure. Progressive pitch technology allows the impeller to grab a given mass of water per blade at a given pitch angle (the lower pitch number) and transition it into a more aggressive pitch (the larger number). Add to Wish List Add to Compare. They do not represent your craft's potential performance at acceleration and top speed, but is simply the pitch ⦠You may also decide to add more horsepower, if so, you will get to a point when that great impeller is simply not aggressive enough to provide the added performance to match the new power. Quite simply, the more you understand them, the better decision you will be able to make when you decide to have yours modified, repaired, or replaced. A larger pitched leading edge can grab too much water, thus over-loading the engine and reducing acceleration. The prop of choice for a 951 is a Solas Concord 15/20. 's have included some form of stainless and or progressive pitch impeller that was chosen to give the best all around performance for a given craft, based on the torque available and the rpm produced by a given powerplant. Considerable changes in elevation merit having Impros reduce the pitch of the existing impeller to allow the motor to spin up to its peak level. SWEEPS: Mariner introduced this design a couple of years ago to the watercraft industry. Remember, water is not just forced backwards on a blade, but travels outwards as well. $395.00. Unfortunately, that is not always the case, the OEM impeller is designed to accommodate a wide variety of users, so they usually make a good middle-of-the-road impeller. Please check the application chart ⦠Get it Wed, Nov 4 - Mon, Nov 9. Many of our customers use us for special pplications, or custom impeller work. STAINLESS STEEL: The first big leap forward was the use of stainless steel in place of aluminum. When you need a new impeller or handling components, your impeller, or entire ⦠The rake of the Nu-Jet impeller is so aggressive that it would be impossible to have overlapping blades given the hub length available. The current state of impeller development is somewhat evolutionary, as opposed to revolutionary. Their primary goal is to make impellers that offer better performance than the impeller included with each new watercraft. Every craft is a little different, as is the riders' performance desires, you may have a great performing impeller in the craft now, but as stated in the Weight section above, you may want to squeeze every bit of top speed or bottom end out of it. The Nu-Jet Destroyer has merit, similar to a chopper prop in outboard performance circles, but with the outer edge of the blade cut-off. Sort By. We test many impellers on a wide variety of watercraft, so we can inform you of the best possible recommendation available. Aftermarket impeller manufacturers are somewhat limited in what they can develop. You're currently reading page 1; Page 2; Page 3; Page 4; Page 5; Page Next; SRX-CD-14/19 SOLAS IMPELLER CONCORD .

This will allow your engine's Rpm's to come up quicker and higher than that of the original impeller in stock form, or the normal recommended impeller. The pitch of an impeller can be deceiving, because of the many geometric differences in impeller designs, even from one manufacture, there is no correlation in pitch between various impeller models. There comes a point of redundancy with overlapping blades in that increasing blade length much further brings us full circle back into complete convolution. The carts the aftermarket companies give are very good to go by. The duct controls water and forces it backwards as opposed to a propeller which allows water (or air) to slip outwards. If you are higher than 4000 feet above sea level, we recommend that you choose 1 pitch combination lower than what the recommendation charts generally list. With a varying amount of riders and cargo, the weight being carried on some craft can fluctuate to more than 500 pounds. This impeller is capable of giving your PWC an incredible boost in its performance. That is not necessarily the case, when an impeller is designed. $252.95 $ 252.

In a jet pump application, this would only take place if the volume available between the blade-face and the blade-back at the entrance... exceeded that area available at expulsion. Considerable changes in elevation merit having Impros reduce the pitch of the existing impeller to allow the motor to spin up to its peak level. (Leonardo de Vinci). Altitude can play a major role in watercraft performance. But the product was made available by a pioneer in the jet-pump industry and has strong technical merit if connected to the proper design and material. A narrow hub allows more water though and gives more blade area for acceleration. This will allow your engine's Rpm's to come up quicker and higher than that of the original impeller in stock form, or the normal recommended impeller. There have been a variety of impeller designs introduced through-out the development of the jet ski years, and later the personal watercraft era. Progressive pitch technology allows the impeller to grab a given mass of water per blade at a given pitch angle (the lower pitch number) and transition it into a more aggressive pitch (the larger number). This also decreased the hub diameter making for a larger area in which water could pass through the pump. But still one fact remains, a ducted propeller (shrouded) produces greater efficiency than its open counter-part. Show. The future of pump and impeller design is in REFLEX TECHNOLOGY. Model Year Engine ... All "R" model Solas impellers are placed in a pitch-block before leaving Solas to ensure accuracy for optimal performanc MakeModelCC / HPYear Sea-Doo GTX LTD Super Charged 215 1503 2006 Sea-Doo ⦠We're making it easier to shop form the comfort of your home with impellers available online for most Sea-Doo models. This will result in increased speed and/or acceleration in most circumstances. The relationship between the impeller and pump exit nozzle diameter is also critical to the performance of the watercraft. We specialize in one thing- the watercraft pump. By combining smaller pitch at the leading edge and transitioning to a larger pitch at the trailing edge, you effectively get the best of both worlds. Acceleration, Centrifugal Force and Velocity. To better understand how impellers work, we must examine the jet-pump, because the impeller by itself will only scatter water, and is highly inefficient. Following the rule, going down to a 14/19 pitch ⦠The venturi works on the principle that a restriction or reduction in line size will cause water to accelerate if the same volume is to be realized at the other end of the restriction/reduction. opposed to transitioning the water along the blade. Sea-Doo Impeller GTI 130 / GTI SE 155 / GTI 130 Rental / GTI LTD 155 2009 - 2015 American Turbine brought this to the market only to find that the watercraft industry was dominated by names like Skat-Trak and Solas, and nobody paid attention to them, so they pulled out. The following are some basic, yet important factors that we feel you should know. Newbie's think the steering nozzle size is what dictates thrust. Every manufacture is differnet in there pitching so it is hard to say. All of the impeller recommendations are based on each craft's stock nozzle diameter. Take a look at the Q&A section of our site, where you can find a lot more information regarding impellers and how to make the right choice. If you are wondering what pump/pitch/impeller your stock Sea Doo uses, look up the year/model of your Sea Doo PWC and Boats. The GTX is easier than a GSX, but harder than a XP. Sometimes we can also squeeze a little speed out of a craft carrying substantially less weight than it was designed to by raising the pitch of the impeller. PROGRESSIVE PITCH: Smaller pitch gives greater acceleration, but reduces top speed. Note: This chart is sortable by clicking the column title. Add to Cart. Without overlapping blades, this impeller may not create the vacuum necessary to keep a personal watercraft traveling at 60 mph glued to the water. Good luck. With the right pitch, this design could produce greater acceleration and top speed in smooth water, but may limit performance in rough water due to the loss in vacuum. A swept leading edge will slice through water, reducing cavitation, as opposed to a straight, perpendicular to the hub leading edge that "chops" through water (the industry standard), thus increasing laminar separation at the tip. The more weight being carried, the more bottom end you will need to get up on plane at a faster rate. A common assumption in this industry is, the more horsepower you have, the higher pitch impeller needed. How to chose a Sea Doo impeller for the proper performance and model. Sea-Doo PWC Impeller Chart. Your over thinking it. Using the impeller that was designed for sea level performance restricts the motor, because the lack of oxygen to your engine will not allow it to run at it's peak performance combined with the sea level impeller. At the same time, a smaller pitched leading edge reduces laminar separation due to a lower pitch angle. The stock impeller is a compromise between the two. When the leading transportation manufacturers begin incorporating more advanced pump designs, i.e., dual-stage axial flow pumps, surface piercing jet pump drives, variable geometry venturis, vacuum enhanced intake gullets, and some of the other technologies that we pioneered into production vessels, we will begin to see an entirely new era of impeller designs, sizes, materials, applications and results. If the leading edge angle is too agressive it creates a paddle effect that "slaps" water as opposed to transitioning the water along the blade. Owners of watercraft modified to limited or more need to remember that a higher pitch does not always mean more speed, motors have a range that peak horsepower is produced, and the impeller ⦠Unfortunately, that is not always the case, the OEM impeller is designed to accommodate a wide variety of users, so they usually make a good middle-of-the-road impeller. It is also possible to create a true variable pitch impeller with no moving parts. SOLAS also has developed new impellers for other pumps. We specialize in one thing- the watercraft pump. We specialize in one thing- the watercraft pump. Page. I personally like the stock impeller. Horsepower With the many different manufacturers and models of craft available today, there are also different size motors. As a blade rotates, it pushes water back (and outwards due to centrifugal force). This decreased the necessary amount of metal needed for strength and thus increased the area available to create thrust. © 2019 www.impros.com All Rights Reserved. 95. NARROW HUBS: This dates back to the stainless instead of aluminum theory. It has been around for many years in Australian Jet Boat Racing. The design has good technical merit but inherent limitations. So if we want to raise our rpm's we should choose a lower pitch impeller. It's unfortunate that many new technologies do not find their place in the market because of consumer skepticism and lack of education. Sea-Doo Impellers ⦠If you examine a progressive pitch impeller from the side, you will see the pitch angle of the blade is constant where it is attached to the hub, but the outer edges of the blade are not. At Impros, we take the responsibility of educating people about the many variables of PWC impellers very seriously. A larger pitched leading edge can grab too much water, thus over-loading the engine and reducing acceleration. I figured I was over analyzing. Some are designed to carry 1 person, and today, there are some available that can carry up to 4 people and a lot of cargo. They do not represent your craft's potential performance at acceleration and top speed, but is simply the pitch progression of the outer blade angle. For instance, comparing the stock impeller's pitch to a performance design from Skat-Trak to gauge the aggressiveness of the impeller would be an inaccurate reference. Chose the correct propeller for your boat. This becomes more pronounced in a helicoil design. Although each craft is equipped with a good all-around performing impeller, heavy loads make it harder for the engine to respond as quickly. Please email us with any questions. Impros is a Personal Watercraft Impeller Repair and modification service. This is where the term PROGRESSIVE comes from. Take a look at the Q&A section of our site, where you can find a lot more information regarding impellers and how to make the right choice. Solas SD-CD-15/23 Concord SeaDoo impeller has unique blade design that delivers remarkable thrust take off, improves acceleration and top speed 2+mph on PWC. There comes a point of diminishing returns on this as well, i.e., reduced rpm, cavitation, etc. In most cases, engine modifications will dictate the need for an impeller better matched for the torque and rpm available from said modifications. We specialize in one thing- the watercraft pump. All of the impeller recommendations are based on each craft's stock nozzle diameter. The amount of horsepower is figured in with the weight, peak rpm level, and many other factors. Pulling a water skier or knee boarder is a good example of when additional low-end thrust is beneficial. The reason is simple. The bottom line is, if you normally carry more or less weight than the craft was designed for, Impros can probably help. JavaScript is disabled. This concept works much like a catapult. Some are designed to carry 1 person, and today, there are some available that can carry up to 4 people and a lot of cargo. We specialize in one thing- the watercraft pump. a 21" pitch propeller should move a boat forward 21" for each revolution, assuming there is no slippage) ... Sea Doo Impeller Most of the O.E.M. As water enters the leading edge of the blade, it is ACCELERATED. In theory, this is true, similar to "blade-slap" with rotors on a helicopter when descending.
