Our goal is to educate you about the purpose and function of many of the Crusader marine engine parts required to keep your boat running smoothly. Whether you're a veteran seaman or a novice, one thing you all know is that a boat comes equipped with hundreds of moving parts.

No one person can know everything there is to know about the proper functioning of every boat part. That's why we've tapped the collective wisdom of our long-time technical experts to share their knowledge and expertise.

What You Need to Know About the Crusader RP061022 Impeller Kit

This Crusader impeller kit is unique to the Crusader/PCM engine product line. It was engineered and designed by the Pleasurecraft Engine Group specifically for their Crusader and Pleasurecraft line of engines.

This impeller kit comes complete with everything you’d need to change the impeller in the pump; the pump cover o-ring and the bolt o-rings are all included. It's good practice to carry a spare impeller kit onboard. If you’re on the water and the impeller fails, your choice is to run the engine and overheat it or to drift and wait for a tow.

How the Impeller Pump Works

A flexible impeller pump creates a vacuum which pulls water to the pump and pushes it to the engine. To function, it draws in seawater on the pump inlet side as the impeller vanes compress and moves the water through the pump to the pump discharge port.

In many cases, these rubber impeller pumps are above the waterline of the boat and their design makes them able to draw water up through the inlet hose from the seacock and push it through the engine cooling system.

Because the impeller vanes flex and run tight to the housing, they will wear over time. The water that travels through the pump also cools the neoprene impeller material. If cooling water to the impeller is lost because of a restriction or blockage, the impeller is going to heat very quickly and fail. This can happen in just a matter of seconds or minutes.

A sign the impeller is failing is when you see the engine temperature rise above normal on the temperature gauge. Many engine manufacturers today have an alarm system which will indicate when the engine is overheating. It functions like the "check engine light" in your car, but it activates a buzzer instead of a light.

Replacing the impeller at recommended service intervals or when you notice an increase in the engine running temperature is good practice. There are less expensive aftermarket or substitute products available in the marketplace. They may produce quality products but when it comes to a critical part, like an impeller, we like to stick with the OE recommended product. Marine Parts Source offers both. We leave it up to the boater to make the choice.
