Do you have perko latches or southco latches? My 2013 P4 has perko latches and I get water in my starboard rod box and rear port storage box. I think the southco latches seal better. Also I get alot of condensation in the rear boxes. I ordered a replacement latch from BCB and it came with a gasket to help seal it better. The latches on my boat did not come with the gaskets. BCB does not sell just the gaskets, so maybe a small bead of silicone caulk may help. Ed
