Our Guarantee

This short block is guaranteed to be exactly as described and photographed. It is sold on behalf of a local shop and was running when pulled. As an outboard shop, sterndrive engines are outside our realm — we do not test or warranty engine performance, so there is no performance warranty and no returns. What we stand behind is the condition stated here: nothing more, nothing less.

Disclaimer

We use various web resources to cross-reference and describe our parts. These are accurate to the best of our knowledge. Verify by model or serial number that you’re getting what you need.
