Your Water Pump

Use the chart below to look up your water pump impeller or water pump kit.
Sterndrive Water Pump Kits

Mercruiser "R", "MR, "MC-1", Alpha One and Alpha Gen II Sterndrives have the water pump located in the drive.

Mercruiser TR, TRS, Bravo I, Bravo II and Bravo III Sterndrives have the raw water pump mounted to the engine.

We recommend referring to the proper Mercruiser Service Manual for proper service procedures and safety precautions.

For units with the water pump located in the sterndrive, we recommend removing the entire drive from the Gimbal Housing to properly service the water pump. This gives you the opportunity to inspect and possibly service (if needed) the ujoint bellows, gimbal bearing and shift cable components.

Do the job right the first time!

Proper cooling is critical and your water pump must be properly installed to prevent damaging overheating.
Simply popping in a new impeller is usually not a good idea.
Buy a complete Water Pump Kit and Water Pump Base if applicable.
Never reuse old gaskets and be sure to follow all service manual procedures.

Sterndrives are filled with Gear Lube. It will have to be drained to R&R your Water Pump in the drive.
Always pressure test your drive after assembly but BEFORE you fill it with new gear lube.
Do not use a sterndrive that does not properly hold pressure or damage will occur.
Use only the recommended gear lube for your application and fill properly as per the service manual.
