I posted earlier but with a diffrent header. I have a 1999 merc 75 hp. The motor runs great, but when I'm at WOT the motor makes a high pitch bawww for 1 to 2 seconds. This only happens every 2 minutes. I got a response to check my tank vent. I've went thru my tank vent and found no problems with the vent ?? Any ideas.
Also the fuel tank is very hard to fill, it keeps throwing fuel back out after a 1/2 gallon has been put in the tank. I noticed that I have a VERY VERY small leak on the fuel line connector to the motor. Could this be the problem. Should I change the bulb and line
