Hit something in the river yesterday. Engine raced but boat wasn't going anywhere. Found I could limp back to my marina at 2200 rpm. Just bought boat 1989 Cruiser Rogue 2522 with 454 and 5 blade SS prop. Boat is still in water. Pretty sure the hub is bad. Any clue to which outdrive I have? Alpha one or bravo one? I can't get the serial number without taking the boat out. I want to order a hub to fix. Thanks.
