I have just purchased a 2004 283 Release with 2004 225 Yamahas. The boat is awesome and and a tank. I have a question and will have some more i'm sure. Under the console there is a button for pumping out the head and checking the tank level. I have no power to either switch and was wondering if there was something that had to be switched on the make that work? Any help you could provide would be greatly appreciated.
