I picked up my new to me boat last weekend, 1983 GW Trophy 259 with twin OMC Sea Drives. I need a starter for one of the motors, but the trouble I'm having is I can't find a listing to see exactly which OMC motor I have. The model number is 1ABLCNC. The covers on the motors say 2.6L, but to find parts, I want to be sure what I have. Any help is appreciated.
