Hi everyone- I rarely post on this forum but really enjoy reading all the posts and have learned a lot! I own a Starcraft Superfisherman 180. It’s a 2007. My first time out this year I had a serious leak (thank God for bilge pumps!). I figured out it was a crack in the livewell drain tube as I put a hose to the outside of the thru hull fitting and could see water pouring into the bilge. Not great, but at least I found the problem. Here is where I am stumped. I have since plugged both thru hulls drains (2 livewells on the Boat )and capped the raw water intakes just to make sure plumbing was the issue. On a 3 hr fish I had no water in the bilge, yet, when I pulled the drain plug I had a significant amount of water. Recently I took it out again, only to have very little water (not enough to run the bilge pump) in the bilge , yet when I pulled the drain plug on shore a lot of water came out. This boat has been bone dry in the past. My last outing in October I fished over 6 hrs and had zero water come out the drain plug. What I don’t get, is that all this water comes out when I pull the drain plug on land, but isn’t in the bilge on the water. I can only surmise it’s a leak from a rivet or the keel gasket? But why isn’t that water pouring into my bilge? Sorry for being long winded. Just super confused!
