Troubleshooting & FAQ

How do I confirm this fits my engine?

This kit is specifically designed for OMC Stringer outdrives made between 1962 and 1986. It is critical to note that it is not compatible with any OMC Cobra models. Please verify your outdrive model and year before purchasing. You can also compare your existing part numbers with our cross-reference list to ensure a match.

What are the signs that my water pump is failing?

Common signs of a worn or failed water pump include the engine running hotter than normal or overheating, a weak or non-existent stream of water from the "tell-tale" outlet, and visible cracking or damage to the impeller vanes upon inspection.

Some sources say this fits up to 1985, others say 1986. Which is correct?

There can be inconsistencies in application data, especially for older models. While our compatibility table covers up to 1986 for certain drives, the most reliable method for confirmation is to match your old part number to one of the numbers in our cross-reference list.
