I have a Volvo Penta TAMD40B Diesel. I've only winterized small sailboat diesel engines in the past. I've changed the oil and filters already and now I'm onto the cooling system. Today I tried removing the intake hose from the seacock, running freshwater into a bucket and putting the intake hose into it. My plan was to run the engine at fast idle until it opened the thermostat. Shut the engine down and do the same with pink antifreeze until I see it exit the exhaust. Problem was, the engine sucked the water up so fast I couldn't keep the bucket filled with water long enough to get the engine warmed up. Now I'm looking at draining the engine instead. This is a new engine to me and I don't want to cause any damage when the weather gets cold. I try to do most engine work myself but fear I may be in over my head with this one. Is this something I should tackle myself or have it done by a mechanic?
