I just smoked one of my mercruiser 3.7 lx engine my boat has twins.
I'm considering changing both to 229 v6 gm engines. 10 horspower more per
engine.
my question is will the old outdrives fit the newer engines?
the outdrives are alpha 1's. or am I going to have to change out drives also.
if thats the case I guess I'll just have tyhe 4 cylender rebult.
any ideas

out drives will probably be ok, but you're bell housings, mounts,
exhaust , plumbing will all be different. sounds to me like a change
over wouldn't be worth the PITA to do it.

I don't know, though. you'd just have to do some figuring.

I've noticed that the chevy merc bell housings have a number of extra
holes. I don't know how many different engine blocks they bolt up to
besides the standard chevy so I can't say if they are the same ones
used on the merc 4 cylinder. The 3.7 is the one merc made? Not the
chevy 4, right? In any case nothing changes on the transom, it's just
the bell housing. But you will need Y pipes and complete exhaust
systems. Plus all the cooling stuff. If you buy complete merc v6's
then it should be pretty simple. If you are going to rebuild a couple
v6s and put them in you are going to be hunting down brackets, mounts,
and other stuff. On the plus side a lot of that stuff is the same as
the v8's. I'd hunt for some donor boats if I was trying to do this.
