johnson 65hp water in cylinder
 

Hi Folks:
This engine will crank, start almost instantly, then stall. Then
bind a bit, crank some more (actually much more) untill I pull the
plugs.
The lower cylinder of this three cylinder in line is being pumped
with water. I pulled the head off, cranked, and I see alot of water
in the exhaust ports of the lower cylinder. I was hoping for a broken
head gasket. Maybe this will not be too bad. The compression was
good. This cylinder/piston seems a bit tight/dry as it squeeks when I
crank it by hand. Understandable if all the oil is washed off. Could
this be just a blown gasket in this exhaust manifold/box on the side
of the engine? It looks like a pain to change, although I did get all
the bolts loose without snapping!
Thanks for any help/info!
Take Care!

Hi:
I've gotten the exhaust manifold off and apart. Here is a picture
of the broken gasket! http://www.harryhydro.com/ex_manifold.jpg
At first I didn't think I'd get the manifold apart. I baked it in an
oven at 265° for a half-hour and it came apart without prying.
This is a drain hole, not a bolt hole. I'm now hoping I can get
a gasket set for this old motor (1972) for a reasonable cost.
Thanks!
