Re: 1957 18hp Johnson seized

I agree, looks like it is best to take it apart. One problem I am having is parts availability. Looks like dealers in my area do not have parts catalogs that go back that far. If I have part numbers they can get parts, but I have to provide the part numbers. Do you know anyplace this information is available online?

Yam,

PM me your email address and I'll send you the parts manual for your motor.

Sounds like crank bearings to me. Probably the upper one. Pull flywheel and pour some oil down there were the seal is and see if leaks through.

I would do a teardown anyway just to change seals.
