It ain't easy
My friend Joe and I both have H-33's, 15 hull numbers apart. The bilge hoses runs in each are totally different.Hoses appear to have been placed before the floor pan was placed in the hull. Easy for them, impossible for us.My hose exits a hole drilled in the starboard side of the bilge, makes it's way between floor pan and hull into the after end of the aft starboard locker, then makes it's way under the 3 drawers into the head cabinet and overboard.Joe's exits the aft end of the bilge through that large opening there, and makes it's way to the head cabinet. We changed his out, here's how.- Remove the companionway ladder. - At the base of the ladder, against the head bulkhead is a small square of wood trim probably about 3" x 4" (just guessing) held in place by 1 or 2 screws. Remove it, drill or cut the largest hole you can that will allow replacing the wood trim. Looking in the hole you see right through the head door sill into the space under the head cabinet.- Remove the plywood 'floor' from the head cabinet.- From the bilge, snake an electricians wire snake back to this hole. Then bend it 90 degrees through the raised lip of the head's door sill into the space under the head cabinet.- We then used the snake to pull a light but strong line from cabinet, to hole, to bilge.- The line was then used to pull hose from bilge, to hole, to cabinet.As I recall, one of us pushed the hose from the bilge while the other tugged it to the hole (the tighest space is somewhere between bilge and the hole), then under the door sill. I don't remember all the details, but much sailor-like language is required so make sure all children are off the boat.You may have to experiment with different size hoses to find out what will fit. Different size bilge pumps have different sized hoses so use hose that fits your pump, or will fit a replacement pump.
