New to the forum. I am seeking help. Thanks in advance. My motor has been having a problem surging at high rpms. Runs perfect at low rpms. Sometimes trimming the motor up or down triggers the surging. I have done the following:
Replaced all fuel filters and fuel lines, VST, High pressure fuel pump. (Doesn’t seem to be a fuel problem at this time). There is a also NO water in the fuel.
Replaced impeller
Replaced thermostat
Replaced spark plugs
Batteries are two interstate 1000 cranking amps and are 2015’s.
Tell tale pressure is very strong. Every once in a while the beeping alarm will sound right after take off. Once I cut motor off and back on it goes away. I originally found the problem last summer while I trimmed my motor up. At that the point the motor starting surging as if it was going into RPM reduction... but no alarm. I did find a little water leak it what looks to be the head gasket. It drips into the cowling. I do not have any water in the oil. I’m starting to think I might have a blown head gasket. Can someone please help me diagnose the issue? Maybe some test I could run to help. Again.. thanks in advance.
