Does anyone know for sure if there is any difference between the gear reduction starters sold on the Gen V big blocks and the Mercruiser (or any marine) starter. My mechanic insisted I buy a new marine one when installing my new 502 longlblock and afterwards someone told me they are actually the same piece. Have a friend who needs new starter and want to make sure before I give him my gm one. Already have enough paperweights in the garage!
Thanks,
Rick
