That's an OMC model 400 or 800 sterndrive. As I recall, the 400 model was 4 cylinder engine and 800 for V-8's. The shifter in those were problematic.

There is a Fiberform sitting in my yard, not sure who owns it?....probably me!

It has a V-8 OMC electric shift sterndrive. I'll see who owns it if interested.
I get to keep the trailer.....!

got the lower gearcase to spin but when i turn it by hand there is about a 1/4 to 1/2 turn play in the vertical shaft before it starts to spin the prop shaft is that normal or is there something wrong? i don't have the right tools to go any farther any ideas?

Ron,
On the outboard versions ,they measure the Shaft slop with a micrometer.
Too much slop will toasr the bearings and also lets the pinion gear move unless it is a loose spline.There is usually a Keeper nut below the pinion,and they use shims to dial it into spec.
Best to keep it as an assy,with a used donor your best choice.
I`m not an Inboard guy so I may be off base but am pretty sure any major slop over a few .001`s is out of spec.
