Its well over the cav plate in a 55gal barrell. Yes I pulled the gear case after and found no problems. The relief spring/plastic valve clean, free & not deformed. Did spend the $$$ for an OEM pump kit. No I don’t KNOW its overheating. There was minor splash water drops on the head/block no boil or spit there, could hold my hand on the head a second or two. On the 1st start had good water discharge for 30ish seconds then slowed to near nothing, then ran it maybe a minute. Not knowing I just shut her down. It sounds like what it did was normal, I just didn’t run it long enough. When the temp gets above freezing I’ll give it another try. I’d feel better if I could add a real temp gauge but don’t want to bore/thread the casting for a sending unit. I could wire a bulb to the overheat light sending unit in the head. Are they near accurate? What would a ballpark runtime be befor it shows a good discharge stream.
