Specifications

Impros Yamaha Impeller Spacer – 1mm Stainless Steel Pump Shim (SKU: IMYQ-IS)

The Impros Yamaha Impeller Spacer is a precision-machined stainless steel shim designed to fine-tune impeller positioning within Yamaha jet pump systems. Each spacer is 1mm thick and installs behind the impeller, allowing you to move the impeller forward from the bearing carrier in precise 1mm increments for optimal clearance and pump performance.

Proper impeller spacing is critical for maximizing pump efficiency, reducing cavitation, and achieving the correct impeller-to-wear ring clearance. This spacer is commonly used when installing certain aftermarket impellers, including Impros Hooker impellers in Solas 12-vane pump systems, where additional spacing may be required for proper fitment and performance.

Manufactured from corrosion-resistant stainless steel, the IMYQ-IS spacer is built to withstand harsh marine environments and provide long-lasting reliability in both freshwater and saltwater applications.

Commonly used on Yamaha SuperJet, WaveBlaster, and other Yamaha models equipped with 20mm pump shafts and 144mm pump systems.

FAQs

How do I change the impeller in my craft?

Impros has complete impeller installation instructions for Yamaha, Sea-Doo, Kawasaki and Polaris PWC. See Impeller Installation instructions for the person that likes to get in there and do things themselves.

Does Impros balance each impeller they service?

Yes. Each and every impeller that we service is checked for accurate balance within 2/10ths of a gram. Slight rock damage and especially with impellers requiring weld, checking the balance is absolutely required with PWC impellers. Sometimes we’ll find new impellers out of balance right out of the box. We balance each impeller as the finish is applied, eliminating any chance of throwing it out of balance during the polishing process. These measures are proudly taken to insure our customers the highest quality impeller repair available. Ask our competition if and how they balance impellers, we’ve found that they typically rely on the original factory balance.

Does Impros use correct pitching techniques specific to each brand of impeller?

Yes, Impros is proud of our ability to pitch each brand impeller to the manufacture’s specific range of blade angle variation. Impros has a master gauge for every stainless-steel impeller made, assuring an accurate pitch and uncompromised performance, eliminating common guesswork. Each and every manufacturer builds the impeller geometrically different from one another and gauges the outer blade angle in a different way. Only a company with experience will accurately understand, manipulate and repair the blades of the impeller to its original state.
