Congrats on the new boat ! I used an oil change suction pump to get all of the coolant out of the reservoir. I also removed the heat ex changer and opened it up to inspect the inside (found a small impeller fragment) the inside of the HX was in surprisingly good shape with just a light coating of minerals due to the fact that the boat has been in fresh water all of its life. Gave the HX an overnight soak in lime away and replaced the gaskets on the ends.
I also replaced all of the hoses on the engine. By the time I was done I felt that there really wasn't much left to flush and just refilled the system with fresh antifreeze. Everything has been fine since then.
