I have a 2016 19 foot Sea Ray stern drive with a 4.3 liter engine. I have tried using a five-gallon gravity antifreeze feeding system hooked up to earmuffs to winterize the engine, but it overheats. This is after warming the engine up to operating temperature, using the single point engine block drain to drain the water, and then slipping the earmuffs onto the intake in the lower unit to run in the antifreeze with the engine running. Last year, I replaced the impeller of the pickup pump. I found that the impeller that I replaced was fine but I put the new one in anyway.
Rather than chance damaging the engine, I took the boat to the local marina to have it winterized. I explained my previous problems with overheating to the mechanic. He nodded and told me that the overheating issue was the reason he uses a pump to run antifreeze into the earmuffs.
Does anyone else use a pump to get antifreeze into the engine while winterizing? If so, what kind of pump do you use?
Thanks!
