I have a 1971 6hp Evinrude Fisherman, model 6102G, serial J08051. I had the starter gear replaced by a repair shop to the tune of about $100. I believe the original part was some sort of metal, and the replacement part they put on was plastic. Well, the plastic starter gear teeth have worn out in no time, plus it sits kind of loose on the spindle. I am wondering if they substituted the wrong part. The part they used was 318447, what they called a "pinion gear." Labor was $72 of that amount, although it doesn't look that difficult to replace. However, I would like to know if a metal correct part is available for this motor, as it runs great except for this problem. Thanks.
