I ditched the original crappy supra/moomba designed pins after shearing 4 in 2 trips and not able to purchase replacements from the dealer. found 2 of the 4 laying in the bottom of the lake when docked(gotta love kids snorkeling with lots of free time), and all broke at the pivot point, very weak. they told me that they don't stock them anymore due to a poor design and are only selling the ones listed in the very first post. they were out(supra/moomba owners bought them out over the last week), so went to homedepot and bought 4 for less than 10bucks. have not had an issue with one yet. incidentally, that design is the same one used on malibus, mastercrafts and centurions. sometimes the wheel doesn't need re-invented.
