We were out in the montauk this weekend camping and the boat ran great all day Sat. Sunday it cranked up and ran fine for a while. Going about 4000 rpms it started cutting off. The boat had to be towed in. It started up and ran the rest of the day, about 430 in the afternoon it cut off again. The motor is a 90 yam. This was the second time it was in the water since Oct. It had about 5 gallons of gas in before it was filled up on Sat morn. Do yall think it was condensation (water) running through the motor or a bad coil? I dont think it would be major since it cranked up and ran all afternoon. Does anyone have and ideas?

Could water, could be coil.
I don't think water, odds are you would have
Could also be:
Mmm, did you fill up after being towed in
And check the fuel filter on GPs.

I have had a similar problem...come to find out the soder on the pipe that runs from the top of the gas tank to the bottom was comming apart. This caused the engine to suck air, causing the motor to foul out. Just a suggestion!

It has one tank the 27 gal pate tank. I filled up Sat and had problems on Sun. Ran about 5 to 8 miles on sat. Motor had new coil put in about a year ago.

I had this problem and it was the primer bulb.

Well it turns out that all of the possible solutions are wrong. The mechanic says that the thrid cylinder is burned out. Compression is 110,110.30. Something must have overheated the cylinder. I wonder why it would have ran fine and then the next day it messes up. It sounds like it sucked up some dirt and clogged the cooling system. Any ideas why it all of the sudden burn a cylinder out?

A lot of times when only one cylinder burns out it is due to too lean of a fuel system on the individual cylinder. Your cooling system is probably fine. I would bet that something was partially plugging your high speed carb jet for the particular cylinder.
