Bilge H2O
I never liked the idea of having the packing box drip going (sloshing) thru the ribs until it finally get to the bilge. Also never liked the same "birth defect" in the drain for the shower stall -( but I never use that) .My 28.5 had the drip hole in the forward base of the engine compartment, also drip holes on the "outer of center" ribs (to drain when healing) towards the bilge. I know about the oil issues and my engine doesn't leak any. But the shipping of packing leakage between the ribs did bug me.What I did was to go to a 5&10, buy a rectangular tupperware bowl ( about 9x5) , placed it under the packing box (had to carve a crescent out of the stern side upper part of bowl to clear the shaft), and attached a poly (bilge pump) conduit to the forward side of the bowl and ran it thru the engine comparment drip hole, thru the ribs and into the bilge. If I used the shower , I'd do similar rather than have a science project growing in the ribs. I used silicon to glue down the bowl to the fiberglass hull under the packing box so it wouldn't "walk" with engine vibration. So far its worked fine.Jim McCue
