Hey everyone...wondering if anybody has installed a Bilge pump for the Lower Centre Bilge in a 400SS.....Currently the only way to drain it is when the boat is out of the water and the Plug is pulled. The Boat is in the water from May until September , so there is a lot of water accumulation ...and no way to drain.. Kind of an odd design . Just thought I'd ask if anybody has tackled this? Having a hard Time finding where the water is coming from. With an epoxy barrier coat just done..its not coming in externally... either water tank, or drains, or AC lines but tough to find!

Thanks for any input

In the engine compartment? There should be 2 pumps in that space...Pics?

Im surprised there isn't already a bilge pump there? If it is like our 382 fastech, it may be that the hose and pickup is under the cabin steps and the pump is in the engine room. Ours is a diaphragm pump mounted on the stbd side engine room wall

Yes there is a 3 pumps i believe in the engine bay...But there is a centre section that supports both motors...it does have a fitting for engine bay to drain into in on either side of the centre section...but once its in there...only way to drain is the plug....Will post a pic shortly

Yeah I'm surprised as well...If there is one..i haven't found any hoses and it def. doesn't work!...LOL..was thinking of installing a Live well pump with a 1" Tube lengthened to work...Will keep digging!

So the Centre section between engines is about 10" Tall...and that is the cavity with the lowest point in the boat..Leakage, floor drains etc all go into bilge...then from bilge drain into lower cavity..(Epic fail)

I always had the same issue with my 350SS, which sat on a lift all year. Just sucked it out dry with a shop vac periodically.

I don’t really have spot to get a vac in there other than through the 2 x small 3/4” barbed fittings ?
Is that what you mean ?

I have a 400SS and Im still not clear....There is a center drain plug on the transom. It drains any water that gets between the liner and the hull.No Pump. Small area. I vac it dry if im transporting through freezing weather, Normally it would be dry. The 382 has a diaphram that sucks out the under step drain in the cabin. The 2 bilge pumps in the engine room drain all but about 1" of water in the center section of the bilge
