hello all,To start off i have done alot of trolling in the past six monthes.Last trip i noticed a in & out noise or rattling noise at low rpms and also at high idle.changed plugs and ran 3 to 4 ounces of sea foam in a six gallon tank recently.First time out since then boat ran great for about 20 to 30 minutes at wot then it started missing out and it dropped rpms.Idled back to ramp.Middle plug was fouled badly it looked burnt,the other 2 looked fine.Swaped burnt one with a used spare.I got the rpms back but it just didnt sound or feel wright so i stopped and killed the motor when i started it back up there was a squeeling noise that went away.I put it on the trailer.im afraid i will be down for the count please help.
