I've got a 05 STX 12F. It got salt water in the engine compartment last year. Was thouroghly flushed out and used a few more times in fresh water. Then put up for the winter. I pulled it out of the garage the other day when I tried to start it, the starter spins but doesn't engage. I looked in the service manual and I don't see any sort of bendix drive. Any body have any advice , It would be appriciated.
Thanks
