I have a 1989 Sunbird SPL 150 bowrider. The ski compartment always have standing water (about a couple inches deep), I think the rain water from the whole boat just drain into it. so I drained it with a shop vac, and take some pictures. There's a yellow stick that goes to the bottom of the vertical wall at the end of the compartment. I tried to turn it or push/pull, it doesn't move. There's also some drill holes on the opposite side, I think the standing water line is just under those holes, which suggest it drained through them. But since the holes are high, it doesn't drain completely. What can I do to fix the situation? Does the yellow stick connect to a drain? If so, how do I make it work again? Should I drill another hold lower on the left hand side? Has been reading a lot in the forum, always enjoyed the threads. thanks.
