Right or wrong this is how I do it. Get boat to operating temperature on fake a lake. Take 5 gallon bucket full of RV antifreeze and I bought a cheap pump from tooling outlet store and had short hose from bucket to pump and another short garden hose from pump to fake a lake. Hook pump up to battery on car, have son rev car to get pump churning at max rpm and as soon as antifreeze hits fake a lake start boat. Run boat till it comes out exhaust then run till all 5 gallons are gone. Temperature is at normal operating temperature so I know the thermostat is open. Done! Takes about 10 minutes total time.
