not much to clog on the  exhaust bottom end of things…

 

have to tried  pulling the PH and  feeding water in the  entry point of the water tube and then  checking to see  where  and  how much water exits the engine cavities  …back out to the   outside world    ?     check the thermostat flow channel               seems it should come out  as fast as it goes in  if  proper cooling is expected from the water pump.

 

if all is ok… recheck  the impeller and pump  assembly & cavities  below

Crosbyman , water comes up the water tube and fills the cavity under the exhaust cover.
There are some picture in some of my first posts which show the bleed holes.  From there it goes out to the water jacket around the cylinders. Everything flowed  nicely when I put water through the passages. No thermostat on this motor.
Thinking ……just thinking all this might come down to a cheap impeller, possibly not pumping enough volume at slow speed when I initially saw the water / steam coming out of the discharge. I really can’t find anything else wrong  on the motor, and I have certainly disassembled and gone through every piece of it!
