I have benn working on a frozen 3 Cyl. 50HP Merc. (1998). I have disasembled the power head and utilizing quite a bit of 'Release All' and Heat, have managed to free everything up. Problem is, I used a mild metal cleaner to remove the rust from the #3 Connecting Rod. This procedure cleaned everything up, although the metal cleaner also removed the cromium(?) finish on the con rod.....is this a problem?...can I simply replace the roller bearing assembly and re-assemble or do I have to replace the Rod also?. (Rods are kind of expensive).<br /><br />Rcb
