What Mercruiser was in a 1982 Imperial V174?

[gl1100ryder]

I purchased a 1982 Imperial V174 open bow last fall for $200. It has a good Alpha One unit on it, but no motor. The fellow I bought it from thought it may have had a 3.0 in it, but from what I've found so far, it appears that it should have a 2.5 120. Does anyone know for sure what this boat should have in it? I need to source an engine for this summer to put in it, but I need to know what is the correct one.

Thank you!

the 2.5 and the 3.0 are externally identical, so either will fit if the boat had a 2.5 or 3.0

So I can use either option then? What years would I be looking for that would fit a Mercruiser outdrive from 1982?

Ayuh,.... Either motor, from Any year can be Adapted to fit....

How much of the motor is missin',..??
It's the flywheel cover, 'n manifold that might be yer sticking points....
You'll need to measure the spread of the rear motor mounts on the transom plate, 'n Match that, with the right flywheel cover....

There is currently no motor at all. Only thing I have are the motor mounts and complete gimble and outdrive assemblies. Aside from that, I don't have anything else except for the boat side wiring.

Ayuh,... Then ya need a flywheel cover that matches the inner transom motor mount width....
And,...
A manifold which the riser matches the down-pipe on yer transom...
