Last year I purchased a 1985 28' O'Day. The hinge on the forward Bomar hatch was broken so I tried to order a new one. Found out that this hinge was discontinued but they made a replacement, P2000-20. If I didn't have a friend, who was a machinist, this refit would never have been completed. He had to mill it and make aluminum spacers. The engineer, who designed this "replacement" hinge, must have never tried to use it. Anyone who needs to replace a hinge on a Bomar hatch should be warned that the tools needed for this refit, are a machinist with full access to a tool and die shop.
