In trying to narrow down where the water came from (other than the non existent riser gasket) I fabricated an aluminum plate like the thermostat gasket and siliconed it both sides installing it between the thermostat housing and exhaust manifold thereby isolating the two.
I removed the hose from transom to the thermostat housing and replaced it with a 0-60 pressure gauge in a 3/8 plumbing T. Second side of the T got an air valve for a bicycle pump, and the third side 10 inches of 3/4 heater hose. The heater hose fits perfectly over the 3/8 T and gets a hose clamp. Other end to the T-stat housing and another clamp.
Pumped up to 16 psi and has held it for over an hour.
The bad news then is an exhaust manifold.
Any suggestion as to what to look for when examining used manifolds?
