I have a 1995 Larson 195LXI with a 5.0LX mercruiser. The engine has been changed out to a 355. I am getting a vibration at idle and through the rpm band. I get the vibration in gear and in neutral. It isn't so much of an engine miss. I am looking for thoughts and experiences that help me on where to look first.
It still has the little 6" harmonic balancer, not sure if that should have been swapped to an 8".
The u-joints in the outdrive shaft seemed a bit loose when I reassembled things.
My thoughts are: Harmonic Balancer too small for new engine, rear engine coupling got bent during removal or install, engine alignment shifted, bad/loose u-joints for the drive shaft, and verify that its not a miss in the engine itself (Compression test etc).
Any other suggestions on things to look at?
I do have a second question also. When I put a new fuel filter in, the pump did not have enough capability to prime the filter and start the engine. I had to take the filter back off, fill it with fuel, then reinstall it. Is this normal, or is the pump weak?
Thank you!
