hi everyone...just got back from 2 weeks in the beautiful adirondack mountains in new york state....all in all the trip was good, but my boat motor crapped the bed the first day...wifes' harry eyeball was visable every day....here's what i know...

drop the boat in the water...starts right up...drive to the dock, about 200 yards away from the launch...everything is great....then as i stop, i see smoke coming out of the engine...and the baby is hotter than haiti.... so being saturday...and somewhat isolated... i go to the local bar and ask if there is a mechanic...i find one...guy comes over, takes my boat to his house.... find the fins on the impellar are gone....
so he puts in an impellar that he fashions to the original...as the nearest town with parts is 60 miles away and not open till monday....

he fixes it... drops it in the water and starts it up...spitting water....turns it off... i go over and try to start it.... i have a heck of a time starting it, but eventually... it runs... 100 yards into the water, it conks out....

we take the head off and see that the head gasket is blown out between two of the cylindars.... burned, melted? .... but the cylindars looked fine with a visual.... i brought the gasket to another guy in town who used to serice boats and he thought that my cylinders weren''t cooked, and that the sputtering, losing power and failure to start were related to not a good seal....and he said bsed on how it melted, between 2 cylinders, he surmsed that water got in both cylindaers.....

does this all make sense? when i was turning the motor over, it was sort of puffing...like aire was escaping....first guy said there was no compression reading on the middle and lower cylindars,which paralleled the melted parts of the cylindar/head gasket.... upper cylindar had great compresion...that part of the gasket was fine....


any ideas.? should i try putting on a head gasket...and going from there? what about the impellar?

THX FOR ANY RESPONSE.....my wife appreciates it....

as long as the head is flat, id put the new gasket in and give it a try.
just watch the temp and dont run it hot again.

Very common for head gasket to fail from an over heat.
If head and deck are straight a new gasket should solve the problem.
If you haven't checked the gearcase you may want to change the gear lube.
Just because you haven't checked it, unrelated to the over heat.

what symptoms would you expect with the head gasket burning/melting? will the motor turn over? what else?

low compression and water in the cylinders.

Replace the impeller with the correct part.
Check the head, cylinders, and pistons for damage/warpage.
Put in a new gasket.

Giver her a try.
