Mercruiser 3.0 Engine Alignment Problems

[mucklestoneuk]

Hi, hoping you guys can help.

Boat is a circa 1986 Fletcher (British boat) we have been restoring.

It has a mercruiser 3.0 and alpha one drive.

Originally it had an alpha 1 generation 1 transom assembly and leg.

We have invested in a brand new (2012 model) generation 2 transom assembly and leg. It is has been on display so never in the water or used.

We are using the original flywheel bell housing and 3.0 engine.

Since swapping the transom the alignment seems way off. The engine seems much to low.

Are there different bell housings on later models? We have the spring washers and fibre washer under the mounts.

Or does it sound like sagged rear mounts? ( They are the originals as far we know)


After spending hours fibreglassing a new floor in and thousands on new transom and leg we are pulling our hair out.

Any advice would be gratefully received.

without pics of the rear mounts it hard to tell, can you rotate the fibre washers or is the rear of the motor sitting on them?

Yes I can rotate the fibre washers, even move them up and down.

then you cant be low in the back, can you lower the front adjusting nuts more

Yes loads of adjustment eitherway. We went from top to bottom on the adjuster one flat on the nut at a time and couldn't get the alignment tool in. The splines just feel low compared to the tool. Is it possible for the rear mount runners to sag.How would I know if they had?
