This extension kit was a perfect fit. Solved the problem I had with a new boat requiring a long shaft but my outboard was a short shaft. Better than buying a new outboard. The team at Bay were great, fantastic customer service.
Got this for my brand new F25 short shaft after mistakenly buying the wrong motor (needed long shaft). The kit is pretty straight forward with most of the instructions. The only part that was confusing was the exhaust seal. I had to call and check and had someone explain to me on the phone that it was self explanitory when you got it in. I still had a little trouble with it, but got it in. It took a while to get everything lined up to bolt together by myself and when i took it out, i didnt end up having the water pickup tube seated correctly and so the motor started to overheat, but after taking it back apart, i found that i had installed the exhaust seal backwards. After resealing it and putting it back together, the motor started peeing and works as it should now. My only complaint is that i wish they would add some pictures installing the exhaust seal the correct way, but overall, this is a great product and saved me a lot of money and i would recommend it to anyone needing to extend their motor to long shaft, all the parts are high quality.
