When my drain failed on my previous P-15, I decided to also solve the
problem with the hole not being on the bottom of the boat.

I put a beckson port on the inside transom and drilled a hole in the bottom
rear of the cockpit sole. Since this is lower than the original outside
transom hole, I also had to drill a new outside transom hole a couple of
inches lower then the original hole. The new hole was right at the
waterline. I used a 90 degree shower thruhull fitting in the cockpit sole
and a conventional thruhull fitting for the external transom. Reinforced
vinyl tubing is put between the two fittings with hose clamps. Glass,
putty, and gelcoat the old holes.

When I redo this on my current P-15, I am going to put the external hole
higher on the transom and use a loop of hose and a straight shower thruhull
fitting instead of the 90 fitting and a straight section of hose. This will
allow the external transom hole to be well above the waterline, but still
drain well.

This modification is really great because you can easily get rid of all the
sand, dirt, and dog hair in the cockpit since the hole is in the cockpit sole.
