I am a marine technician recent grad of mmi. Looking for any suggestions to make the task of aligning a 350 chevy V-drive easier.I was told the best spec. was .002", and is this a two thousanths difference at all measurement points? Or is it a tolarance between say three points? when the engine was pulled I never changed any of the mount adjustments. The boat is in the water, and the engine was pulled to do some transmition work i guess time,patience and alot of adjusting will do it but i cant understand why it is out of alignment when I never changed any motor mount positions.

I answered this already????
Take the coupling apart insert 3 thou= feeler slide it around the coupling if it feels the same drag then it fine.if loose on 1 side or corner adj mounts to fit.then rotate the shaft 180 deg an trans an check again.If it's the same than your OK if not than adj again> If you can't align than shaft could have a bend in it >or a high spot on the coupling > there can not be any rust on the couplings face or adj will not be possible> I have spent as much as 3 hours to get it perfect. From 1 cyc 10 hp to 750hp 892 detroits. Have 3208 cats in my boat.Also if the cutlass bearing is warren or loose or it's been sitting for a long time with the trans out the weight of the shaft not supported will egg shape the cutlass bearing . Get it close an run for a while them align the shaft.An the boat needs to be in the water to get it correct>>Not on a trailer. Or dry dock?????

are you saying there is definitely an alignment issue? it really should be a simple move to replace the engine and align it. it's time to grab that tech manual and read it.
