Hi Ken,
Bet you 2 beers if you look carefully you’ll see “SS1-50P” stamped on that end (by code it’ll have some NEMA code stamped there).
You need SS2-50P, which has 2 not 1 main pins with an “L” bend (and an additional ground plate, not sure, just go by the code).

Get a store credit at West Marine and try the boatersland.com adapter if they allow returns.
In order to avoid charges of hijacking this thread, I MUST say the next 10 days forecast is 79-81 degrees every day, sunny, 10-15, 1-3 ft, zero to 10% chance of rain daily, perfect TomCat conditions. Had to buy more sunscreen and ice almost daily.
2 Fat Tires will do nicely next time we meet.
