Im glad to help. how hot did it get?
did you take apart the exhaust manifold
and riser assembly when you rebuilt the
engine?
If you changed the impeller correctly then
i would look at the riser to be blocked with rust.
try to blow thru the hose when the engine is off
and COLD.
let me know. S

twenty minutes??
is it in the water? or on the garden hose?
you shouldnt run it that long on the hose. It will
get hot unless you have a lot of water pressure.
Air pockets will form and the unit will not cool properly.
How hot is it getting? it will run at 180 to 190o F.
