New rebuilted engine hard to align

[Frenchman Bob]

I have a Mercruiser 5.7L Bravo II 1997, in a 26 fthalf cabin. This last spring I bought a new rebuilted engine (cast number 880, same as I had before) in Ocala FL. My mechanic and I installed it in my boat. After the installation, we found out the engine wasn’t straight with the boat. It had a small angle to the right, and the alignment bar was very very hard to push in and very very hard to pull out. The front engine mounting adjustment was good. We toke the engine out to make sure the flywheel housing was properly bolted to the bloc, and it was.We also checked its condition and nothing wrong with it. The transom plate has never been removed and it’s in very good condition.

Anyone have any idea of what the problem is?

remove the front mounting lags or bolts, just let the pad sit on the stringer ,sightly loosen the rear mounting bolts. Align the engine .
Redrill front mounting holes

Did you check the mounts in the bell housing. Most are bad when older and need to be replaced.

No Idea how you and your mechanic chum did the install, but when I put in an engine I leave it hanging on the chain (hoist thing) until it is in perfect alignment. Then I run the front mount adjusters down so the mounts are sitting on the engine beds. Then I let it down and check it again with the alignment tool with the weight on the bed. Usually need two maybe three tries to get it perfect.
With the engine in place and aligned, mark for the engine mount holes. Lift engine out, drill beds for the mounts. Put engine back in. recheck alignment. Run lag bolts into beds.
Recheck alignment.
