I have a Johnson 115 HP 4 cycle that is bogging down at higher RPMS, it keeps going but hesitates. After I turn it off I notice gas on the water. Had new plugs, filters and oil also lower unit and water pump done. Boat is a 2005 Stratos FS180 and has a check engine light that is on and ringing...
engine starts and water is coming out of the thermostat wire next to # 1 spark plug, is that a replacable part?
Sorry the motor is a 1990 Merc 40hp 4cylinder SN OC225906
I have a 1990 Mercury 40 HP 2 cycle and I put in new impeller kit but did not replace the housing. I was wondering what side the copper pipe goes up, the bend to the shaft or away from the shaft? All gasket were replaced and assembled correctly but I get no water stream.
