Troubleshooting & FAQ
How can I confirm this impeller fits my motor?
Verify that your outboard is a Johnson/Evinrude 4-cylinder model between 85 and 125 HP, manufactured from 1969 to 1972. Cross-reference your existing part number with the numbers listed in the "Part Number Matrix" section.
What are the signs of a failing water pump impeller?
Common symptoms include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "tell-tale" outlet, and visible cracks or stiffness in the old impeller's rubber vanes upon inspection.
How often should I replace my impeller?
For preventative maintenance, it is recommended to replace the impeller every 1-2 years or every 100-200 hours of operation, whichever comes first, especially if you operate in saltwater or debris-heavy water.
Does this impeller come with the woodruff key?
No, this listing is for the impeller only. It requires key type 47-01408, which must be purchased separately if your old one is lost or damaged.
Is this part difficult to install?
Installation requires basic mechanical knowledge and tools to drop the lower unit. If you are not comfortable performing this maintenance, we recommend consulting a qualified marine mechanic.
