My solution is simpler. I found a tubing size at the hardware store that fit snugly into the outside opening of the raw water intake. I got about 15’ piece, fill it with antifreeze and plug one end into the intake and the other into a bucket of antifreeze on deck. I then start the engine and wait for the antifreeze to be sucked through and come out the exit port on the transom. It takes surprisingly long, before the suction starts. I am presuming that means the thermostat controls the raw water flow through the heat exchanger, not the closed loop antifreeze flow? Dave
