I have a 1988 125hp Force motor that needs repair on the #3 cylinder, looks like fairly bad grooves at the bottom of the cylinder. First a little background so you know how I got to this point.
While out on Lake Erie my boat motor overheated while on plain and died, haven't been able to start it since. I suspected the water pump failed and I was right, the Ikey dislodged and jammed between the impeller and the pump housing. I installed a new pump kit. Motor won't start without the help of spraying starting fluid into the throat of both carbs. A couple nice gentlemen on this forum lead me through diagnostics to get me to this point. The fuel pump needs rebuilt so I got everything I need for that and it's done.
Now for the real work. I know I have to pull the head to start this big job and pretty certain I have to pull #1 in the attached diagram. Will I need to pull the entire power head off in order to do this? I feel like I might be getting in over my head but if it's not much more difficult than rebuilding a 650 Yamaha motorcycle motor then I believe I can handle it. Just will require a lot of time and even more patience, I'm sure.
Any helpful hints from the much more experienced outboard mechanics on this site would be greatly appreciated. I'm not exactly sure where to start.
#2 pic is what started this entire project, #3 pic is the bottom of #3 cylinder with light shining through the port
