I have a 2000 Sprint 221 Pro SC, and am having some electrical issues. I have a phantom drain someplace and can't find it for sure. I thought my best bet would be to install a new block under dash and rewire for starters. I have had little success finding info on these boats. i tried your link above and cannot get to the photos. My email is firstname.lastname@example.org. Can you send me something I can possibly open and view? I thank you so much for this. I don't get on bbc as often as I used to due to work schedule. Please correspond via my email if you would.
