I have an old OMC sterndrive I have off the boat to replace water pump and seals and was thinking as long as I have it off I could refinish it. It is really old looking rough white paint on it, looking as if it was just repainted and never sanded down in all its years. It it worth it? Will I run the risk of damaging something, original metal coating etc?<br /><br />If I do go ahead with it, what are the best steps?
