compression test before you go any further, if that cylinder is low, youve probably got a dropped valve. Amazon bore scope that runs on your phone will show you the extent of teh damage. If its a salt water motor, its not worth fixing. Reman powerhead installed will run around $7000+

Ok will do that but what if the compression is good? Should all the cylinders be around 110 psi? And if that cylinder is bad than we are screwed I guess. But before that I have to check the compression. One step at a time. Personally I don't like 4 strokes and definitely do not like electric vehicles. Sometimes progress is not good.

compression should be around 175 depending on the gauge. If its good, take a look with one of those bore scopes, if you dont see any damage, throw plug in it and see how it runs

Will do spare. When you relocate to New Jersey let me be the first one you tell.

Phatdaddy , that's what I have on my wellcraft,a 150 2 stroke Mercury of course and I would love to know like spare and your friend how to work on it. I do know some things but would love yo know all of it. It's really a very simple engine ,just the basics carbs,stator,trigger,switch boxes. Plus the other electrical components I would work with a mechanic just to watch and learn.

Find a Mercury factory service manual for that model. No a Seloc or Clymer or whatever those off brand books are, get the one published by Merc. It will tell you how to do anything you want to do step by step with pictures

When I got my four stroke, I had the dealer order me one for my motor, I think it was about 80 bucks, but well worth it
