I recently bought a 1990 fourwinns 18 ft open bow. the motor has a mod. # of302bmrjvb. according to specs i read this as a 1993. the carb has a 3.0 L air cleaner. it has a cobra stern drive with mod. # 985684. since this motor was changed i'm not sure what year this drive is cause the propeller iboat calls for is a 15 tooth 43/4 gearcase but the prop slides right over everything and i count 13 splines on the drive. i have no idea what year, h.p. or prop i should get. any info would be greatly appreciated.

Re: Cobra question

I believe, that your 3.0L cobra stern drive is a 1985-89, 13 spline, and the 15 spline is 1990-94, which what was, or should of been in your boat.:redface: Hope this helps.

Re: Cobra question

Having a "1989" drive on a "1990" boat is perfectly normal. Even from the factory.

If you have a 13tooth spline, just pic one of the listings for 13tooth, 4 1/4 gearcase. Engine, HP etc are irrelevent, all of the links will go to the same place.

What prop do you have now?
