My '98 SeaSwirl 21 Dual Console has a large livewell in the bow, between the bow seats. It has a drain, which appears to go into the bilge. It runs slowly, and appears to stop draining after a while. There also seems to be a center passage from the transom forward, which could be a central drain. The question is does the fishwell drain it this? If so, how do I clean it out?
