I have a 4.3 v-6 with an OMC outdrive and am wondering if i can use a Mercury Alpha 1 outdrive off of a 305 v-8. Any help would be greatly appreciated .

What year is your setup? Is it a Cobra or a Stringer? SEI produces conversion kits for Cobra -> Merc (some years), but if you have a Stringer you'll have to replace everything & fill the big hole in the transom.
That conversion kit will only work if the Mercruiser drive is an Alpha I Gen II drive, NOT an Alpha I from 1990 earlier.
The V8 gear ratio is also wrong for the V6.
Thanks for all of the info . I guess the gear ratio makes this a non starter. Too bad cause the merc is a free donor . Just do not want to change complete motor and outdrive.
