Transom plate corrosion at bottom near drain hole (PICS)
Hey guys. I picked up an old boat with a mercury outboard and have a question about the transom and drain hole. This boat has a metal transom plate that extends all the way down to the bottom of the transom, with the drain hole going thru the plate into the boat. The previous owner must have used it in some salt water because the bottom portion of the metal transom plate surrounding the drain hole (about a softball size area) is corroded and falling apart. The rest of the plate is good. I was wondering if this will become an issue anytime soon and if I should address it. Im sure eventually the corrosion will spread to the rest of the plate but not sure how fast it might happen.
I was thinking maybe I can take a dremel or grinder/cutoff wheel and just cut off the corroded portion of the plate, leaving the rest in place. Would this be a better option than leaving it?
Id prefer not to have to remove the engine and replace the plate, since I don't have the equipment or means to remove the engine from the boat.
Thanks for any help or tips!
