hurricane Posted June 16, 2016 Report Share Posted June 16, 2016 Prolly not gonna find one. Should just be an in/out for every livewell and a bilge pump. Maybe a recirculating pump for 1 livewell. Link to comment Share on other sites More sharing options...
Ecclerigg Posted June 17, 2016 Report Share Posted June 17, 2016 We had some work done on our old 1999 Maverick. You can see the three livewell drains on the external shot of the rear of the boat. Under the cheese grater were three livewell intakes. Two on the bottom, one on side. Ours was a 1999 boat and I think the design of the hull changed slightly at some point after ours as the close proximity of the livewell intakes and the starboard trim tab recess created a weakspot (See how close they are in photo). Look for leaks on the cheesegrater screw fixings, cracks between it and the trim tab recess and leaks around the intake fittings. Link to comment Share on other sites More sharing options...
