Lower unit installation
I am having difficulty putting my LU back on my old 60hp 2S Merc, after doing this job probably 20 times before I was surprised when it doesnt seem to go the last 8 to 10mm and I am reluctant to force it.
Everything seems right, drive shaft in the splined socket, water tube in water pump housing, exhaust in and gearshift in socket.
It feels as though the drive shaft socket in the crankshaft is blocked with something and no I haven't put more than a smear of grease on the splines. The small pin at the end of the drive shaft is free to move but has a powerful spring in it
Could this socket get gunged up, allow the Lu out but not back? Think I might buy a boroscope and have a look up there.
Has any member had any problems like this before.
I would rather not take the block off the upper leg!
Any ideas gratefully received.
