I don't recall Formula ever putting a thru hull fitting along side the hull from factory. All thru hulls spill out the transom under the swim platform so you don't really even hear the water dumping out

I had a goofy situation. When I upgraded my 525 boat to 700's the roost from the NXT's and the K planes at mid speeds 50-60 would shoot a blast of water at the water discharge dumps under the swim step! I had to move the bilge pump outflow to above the drives under the swim step. No big deal but I could not figger out why my bilges were always full after a run . I had another boat run next to me and found the issue. I dont like check valves to I just relocated the thru hulls. 2005 382
