Identifying Your Model Year

*Please replace "NN" in part number with the model year of your motor (not your boat, they may be different). 1998-2001 model years can be identified by a serpentine accessory belt, while 1994-97 Magnum MPI/EFI's will have "v-belt" type accessory belts. Additionally, 1997-2001 motors have the "Cool Fuel" system with no mechanical fuel pump, while 1994-96 motors have a mechanical fuel pump in addition to the electric pump.

Model Year Accessory Belt Mechanical Pump
1994-96 V-Belt Yes
1997 V-Belt No
1998-2001 6-Rib Serpentine No
