Hello everyone,

First off I have a 1997 Manta Ray 18' with a mercruiser 3.0 with an alpha one drive I think I have spun a bearing in the motor and now needs to be replaced I was wondering with the costly expense of another 3.0 is there another engine that I could possibly put in my boat that would work with my existing alpha one drive?

thanks
Chris

Ayuh,..... The only motors that'll fit without other modifications is the 2.5l, 'n the 3.0l boat motors,......

No car motors will work,....

Years ago I bought a nice (3.0) bowrider that had not been winterized properly and had a cracked block for a steal. I then found a similar wrecked boat (slammed into a piling, did not sink) for the good 3.0 cheap. Swapped the engine into my boat and sold the outdrive and other extras and more than broke even. Only cost me a few weekends and ended up with a good boat that I doubled my money on when I sold it plus new owner got a great deal on it as well. It was simle if you have a little mechanical know how and standard tools. I borrowed the neighbors back hoe for a few hours to remove bad engine and set new one in.
