I have been working with an old launch that has a beautiful Strauble single cyl, two stroke engine in it. We can get the engine to run quite easily but the cooling water sometimes stops without any aparent reason.

The water pump is a piston driven by an eccentric on the drive shaft of the motor. We have replaced the graphite packing and greased it well. There are two new check valves on either side of the piston and a good water screen upstream. We have verified that all of this works well.

The water exit plumbing is a mystery to us. There is a fitting on the cyl jacket that has two water lines coming out of it. One line goes directly to the exhaust manifold, below the fitting. The other line goes to a valve and a longer line that enters the exhaust pipe about 18" downstream.

We have had some success playing with the valve when the water stops but don't understand this system. Please help us figure out this final link to fully enjoying this boat.

I have two strauble single cyl engines one 4 hp and one 10 hp. Sounds like the the cooling system on yours is the same.On my engines there is a check valve on each side of the pump the water enters the block low and exits through a bolted on combination water jacket exhaust manifold.My theory is the valve controls the water to the exhaust pipe while the larger outlet pipe goes to a thru hull fitting.I am only a few miles from you in Oconomowoc and would like in touch.

I have solved the cooling problem. I had installed check valves that have a swinging bronze gate. At low speeds (hand rotating) it pumps fine but at running speed (still quite low by most standards) the gates hang open due to inertia.

I installed spring style check valves and it cools perfectly.

Brad came to help me with this and now the engine is running fine.
