Troubleshooting & FAQ
How do I confirm this impeller is the right one for my motor?
The best method is to match your existing OEM part number to the numbers in our Part Number Matrix. Additionally, check your engine's model, HP, and year against our detailed compatibility table. Visual comparison to your old part is also recommended.
What are common signs of a bad or failing water pump impeller?
The most common symptoms include the engine overheating at idle or low speeds, and a weak or non-existent stream of water from the "tell-tale" outlet. Reduced engine performance can also be a sign.
How often should I replace the water pump impeller?
As a preventative maintenance item, it is recommended to replace the impeller every 1-2 years or every 100-200 hours of use, whichever comes first. This interval can be shorter if you frequently operate in sandy, silty, or saltwater conditions.
What is the difference between this part and the OEM version?
This is a high-quality aftermarket part designed to meet or exceed OEM specifications. It is made from comparable materials (neoprene and brass hub) to ensure reliable performance and a proper fit, offering a cost-effective solution to the original.
Can I install this impeller myself?
Yes, this is a common DIY task for boat owners with basic mechanical skills and tools. The key is to ensure the new impeller fins are bent in the right direction upon installation and to lubricate the housing well.
The listed warranty information seems to vary. What warranty applies?
Different aftermarket brands may offer different warranties (e.g., 1-year vs. limited lifetime). This specific product sold by Sea Sierra is covered by our standard 1-year manufacturer warranty against defects. Please see our warranty policy for full details.
What is the difference between an OEM and an Aftermarket part?
