question on motor replacement

[isimar]

i have a 1971 mercruiser and this particular year they decided to install a renault 90/96 with the mercruiser tag on it..don s mentioned that it had a "O" drive also....being that it's next to impossible to get parts for the renault, would a 2.5 or 3.0 bolt up to that outdrive ? i have a line on a good rebuilt motor w/drive for arount a grand, but don't know if the newer drive would match the holes in the stern.

and what is the difference between the O drive and the Alpha units ?

this boat was a freebie and it's in nice shape or i wouldn't bother.

Ayuh,.... What you've got don't mix with anything newer...

That's Why it was a Freebie,... it's a pile of Parts, 'n nothin' more...

Re: question on motor replacement

if i bought a new mercruiser motor and drive unit, will they fit the bolt holes or am i looking to modify ?

it was a freebie because the 85 yr old gentleman wanted a good home for it because it's been so good to him for so many years, and i help them when they need it.

Ayuh,.... a 3.0l from 1991 to present....

A 470 is equal, 'n on par with what you've got now...

Re: question on motor replacement

what am i doing wrong here ? twice i've posted about my mercruiser motor in the mercruiser section and both threads have been moved.
i'd like to know so i don't keep making the same mistake....besides, it's extra work for the mods and i know they're busy enough.

Re: question on motor replacement

replace isn't a repair ?
