Reply To: 1981 Evinrude 4.5 HP Bolt torque

Thx guys for the torque spec and the info about saltwater.  With torque that small, I think I’ll use some thread-locker.

When this motor was used, 25-30 years ago, yes – it was used in saltwater on the gulf off Florida, so that could have caused the pump housing to crack.  There was white granular stuff that came out on the bolt threads,  and not being a guy that sees saltwater motors, I assumed that dried up stuff was dried up thread-locker.  I’ll rinse out and lube the bolts and bolt holes.   I’ll do the same for the plastic seal above the gearcase.  I will not replace that if I can salvage it because new ones are $149.00!   There is a very small, partial crack in one corner of that which was could well have been caused, as Fleetwin said, by salt.   After each saltwater use, it was run for a while in a bucket of clean water.   I see no other signs of salt corrosion on this motor, and it’s new home will be on a lake in central Minnesota – so no more salt.
