1995 Force 120 won't start

[Boat no worky]

I purchased this boat 2 months ago and the boat was not peeing during idol, I replaced the impeller and it works great. The last few trips to the lake the boat has become touchy when starting cold, even started to die in neutral randomly. So I took the boat to the lake the other day and it would not start, I thought it was the battery so took the boat home put the battery on a charger and the boat started in the driveway (the battery is 2 months old). The last trip to the lake the boat ran for 10 min and shut off, the flywheel rotates slowly about a quarter turn then stops. We replaced the battery, then the starter, cleaned all connections, by passed solenoid, same results. We pulled the plugs and flywheel spins normal. When tested with volt meter, seems to be drawing an excessive amount of power. Any suggestions? Thank You

You may have a bad head gasket allowing water into a cylinder.Sometimes the plug on the bad cylinder will be unusually clean.Or you may simply see water on the plug.Try a compression check.
Also be absolutely sure all connections are clean and tight especially all grounds.
