hello, first time posting here, but been reading alot. i bought the boat a couple weeks ago, took it out a few times, it starts ok, idles ok, but tries to die when giving throttle in gear. if i play with the controls a bit i can eventually get it to speed up but it only turns about 4500 rpm. i pulled plugs and they are all wet, 5 of them look like fuel. the 6th looks like water and the piston looks steam cleaned. i have been reading the forums here and from what others have said it sounds like a head gasket to me because taking a compression test 5 of the cylinders are around 90psi +/- 2psi the one with the water is around 75. does this sound right to you and could replacing the one head gasket get the boat to rev up the rest of the way?
or should i look into doing more extensive repairs? all coils fire good and shock the crap outa me when i pull wires while engine is running. engine doesnt drop any when i pull the one off cylinder in question and the carbs were recently rebuilt. i think the guy who owned it before was scared to do much, because the coil on the cylinder in question looks brand new. but the heads look like they havnt been touched in years. im new to outboards so i hope i provided all the neccissary information
