Reciently bought a old sail boat and started working it over.
Its a 1968 29' Columbia
with a Palmer p60 gas engine
After replacing all spark related items, rebuilding the carb, and the water pump.
It would run at 160 F. for about an hour then slowely loose power and die.
It would then not restart and run, it took about 1 hour and then it would again run for a while.
Convincd it was overheating, we rebuilt the water pump a second time and
opened all hoses to and from the pump up one size.
This required drilling and tapping the block water inlet plate. to accomdinate the larger pipe size.
The engine now runs at 130 F. and water in notacibly in greater supply
at the discharge.
Convinced after a few pratice laps at the Marina, and some dock testing.
We once again put out to sea, and once again.
The same thing occured.
One hour, then loss of power and stall.
After cooling 1 hour, we can again get back to motoring.
The craft is underpowered with this old 22hp engine.
We are out of ideas.
Any help would be appericated.
PS
Are there any high performance parts avail for this engine, to bost HP.
thanks again |

Dano,
Did you put on a new coil? That engine should get your boat up to hull speed with ease.

Did you clean the air bleed line. I think your problem may be air/steam is bulding up in the block and forcing the cooling water down the sides of the cylinders causing them to over heat when at the same time you see normal operating temp and plenty of water going out the exhaust pipe. The air bleed line is provided to insure this cannot happen. It tends to be overlooked in routine maintenance and it can cause a lot of trouble if it isn't cleaned at least once a season. |
