Mercruiser 3.0 to Mercruiser 4.3 swap

[markhodges78]

thought you were swapping in the whole long-tail

I would try to keep the drive whole vs splitting if you have access to the whole drive from behind the 4.3

Yes I have everything the whole boat with the 4.3 still in it all the way to the prop.. I just don't want to remove the transom plate and the sorts if I don't have to... I didn't want to risk having a leak at the transom

Replacing a old seal with a new seal will further guarantee no leaks, so long as the transom is not compromised

Yes you do have a valid point
