I purchased a new 07 175 stinger two weeks ago. Seems the aft livewell drain leaks some where between the livewell and the transom but not where drain goes through the transom. The problem is when the boat is in the water the drain is full of lake water and leaks into the bilge. A lot of water approx 10 gal. in a 8 hour period. Anybody else had this problem? Lowe is telling me that gas tank, subfloors, bulkheads etc got to be removed to correct. Lot of rivets spot welds etc. Dealer will not touch it. Please tell me there is a better fix.
