I was wondering what the guys who leave their sterndrive powered boats in the marina and use them all winter do to prevent freezing. Specifically those with a heat exchanger, but raw water cooling for the manifold and risers. Ive been getting tons of conflicting advice from not doing anything, to installing different drain plugs (to make removal easier so it can be drained after every use) to adding a heat source (concerned with a gas engine). Any thoughts or suggestions appreciated
