Thanks for the encouragement guys. I've removed a couple of powerheads on newer engines and a mate brought his oxy gear around to get the powerhead off a 2 stroke 90hp Yamaha which turned out not worth repairing due to crank scoring.
This merc looks difficult because the nuts are half rusted...
Yes it is the 4cyl 2 stroke. I think the shift shaft can't be removed without taking the powerhead off but yes it looks like the shift shaft is the only thing stopping the upper mounts separating completely. The top of the motor moves back half an inch same as OP until the shift shaft stops it...
Hi Gerry are you still on this page? I would appreciate your guidance on replacing the upper and lower mounts on the same engine as above.
Thanks
David
