Hey Guys, just got my bill for winterizing and on it says that the exhaust flappers need to be replaced. I think I have an idea what this is from doing a search on web buthow much would this cost to replace or better yet how much time should it take. The engine is a 2001 (i think at least the boat is a 2001) mercruiser efi 5.7 engine.
Thanks,
Thanks,
