I think I blew my head gasket.... when I clean my boats and feel lazy sometime I leave the ear muffs hooked up to the motor. I have a routine in practice for years for this though. If I do leave the muffs on I will leave the hose attached so that I remember to take the muffs off later. This has worked great since I am the only one that uses the hose. Well since we moved last month the hose is now being used by more than one person. Apparently the hose got disconnected from the ear muffs with out me knowing. So... Sunday night I am going to go snook fishing for an hour or so. Get to the ramp choke on, no gas and the motor starts up as usual and then dies. HHmm that is funny. Oh well it has sat for a while must just be stiff in the joints. Fire it up again. Idles for a few seconds and then dies. Choke back on and turn the key. Starts up, white smoke comes out and idles for a second or two then dies. Ok give it some more gas. Turn the key, starts up , revs high (as it should at this point), let off the gas and it idles for a second before dying. Try the same thing again but this time open the gas up and it bogs out, still with white smoke. Long story short. Choke on, with gas or with out gas, dies out. Give it gas and it bogs out. Choke off, with our with out gas, dies out. Give it gas and it bogs out. So remember those ear muff.. Well I get back home and they are still on the lower unit!!!! Pushed back, not quite covering the water intake on the lower unit but still some what covering it. Get it back home and try it again, out of the water. Not as bad but still the same story. Ok check the plugs. Dirty, like it is mixed rich, but not water.... HHmm Now I am puzzled?? Idle and it dies out while producing white smoke. Give it gas and it revs up with white smoke then bogs out. Gotta be a blown head gasket right??? But then no water on the plugs suggest that the head gasket is not blown. Can some one help me make sense of this? PLEASE!!!! OH BY THE WAY... while trying to start the motor in the water it was pissing strong, as usual.
