Luck was not in my favor today. The head gasket did look terrible. However, the issues go much further than that. I attached pictures of each cylinder. Of course 1 and 2 look fine, but cyl 3 is rough. Theres is significantly more play in piston 3 and it looks like somebody threw ball bearings...

Thanks for the replies! I only had two screws in the air box for testing purposes. Unfortunately, the serial is no where to be found on the motor. It appears the tag was taken off when somebody repainted it. Not sure why I overlooked the simplest troubleshooting step and forgot to do a...

Hey all, I recently acquired a boat with (allegedly) a 90hp Mercury Force. I cleaned the carbs thoroughly and got it running, had to adjust the throttle cam to get it idling. It will rev up just fine but sneeze a puff of smoke from beneath the flywheel which is very odd. I’ve heard of the “lean...

Whichever conclusion you would like to bring yourself to is fine by me. I can understand everything that’s been said and if not then I’ll ask questions.

You haven’t taken a guess that maybe the reason I’m still struggling is because no one has given any useful advice ? Haha, you’re a funny guy

No oil under flywheel. Here is the plugs. Probably about 2 hours on them.

Will do, but I don’t know why nobody is listening when I say it’s not a misfire. I did the bottom cylinder and no abnormalities with the timing light. It is NOT a misfire!!! Starting to think this forum is useless lol.

They’re new champion plugs

No I only read the top cyl, I’ll go do the bottom right now. Give me a few minutes

I’ve used a timing light. Am I looking for a missing flash? If that’s the case then there’s none. The light pattern was very consistent.

Yeah I just don’t have the manual to do so, and it’s not very hard to observe that the butterflies are opening and closing as they should.

Yes Yes and they are fully open at WOT, how do I check for an intermittent miss?

Yes I have ran a timing light and it’s perfectly in time. No I haven’t done a link and sync, but the cam roller is on the mark where it should be and the butterfly’s open as they should.

I just tested it with the muffs and yeah it actually does the same exact thing it does in the water.

Yeah you’re not wrong, but this is not a matter of misfiring. I’ve ruled out that out already by pulling the wires while it’s under load.
