I am in the process of overhauling the lower unit on my Yamaha 60hp and have come to a halt.
The water pump, impellor etc all came apart without a problem
The prop shaft is and gear box is not.
The first large outer ring came off reasonably easily using a punch and hammer to tap it around. The next inner component, large threaded Shaft carrier will not budge.
I have tried Heat (plenty of heat) and long soaking from hot in Plus Gas then tried Hammer & punch, Large lever and lots of brute force but it won't shift at all.
sorry if wrong terms for parts used
Any suggestions would be welcomed.
