Powerhead stuck on 55 hp 1995 mod

[CoastGod]

Hello all!

Like many other owners of older Yamaha outboard engines (it seems), I am forced to replace the "shift rod" because it is very corroded and it is too weak to stay in its correct position when shifting gear. In order to do this, however, I have to remove the powerhead. So I have now unscrewed the eight bolts holding the powerhead to the lower cowling (?). When I pull it, it is "wobbling"; it does not feel "corroded stuck" but it feels like something still holds it stuck. This may be two "steering bolts" (not sure of the english term here), but I find it a bit strange that these should be so resilient.

So, I am very interested in hearing any advice, especially from others who have also removed the powerhead , and of course if you happen to own a Yamaha 55 hp from the 90's

some have a stud at the very back.
make sure the shift bracket is disconnected from the block and the lower unit already removed.
I am amazed the bolts cake out.

Thanks for the reply, rodbolt17!
Ye, have removed the shift bracket and also the lower unit. The bolts came off quite easily, but probably a good idea to replace them..

Hm, a stud at the back? Do you mean like one of those with threads on both sides without head? Or a bolt with head? Can't see this in the manual, but I will check for it. I guess the worst case scenario would be to remove the mid section of the outboard? But will try more this evening.

Now I was able to get the powerhead loose, by using a crowbar and a lot of force.. So it was just corroded to the bottom cowling/gaskets... Cheers
