- 7.5 mercruisers EFI,MPI (twin) Hurth V-Drives
I have 7.4 mercruisers MPI MIE the fuel pump and the raw water pump are one unit driven by a v-belt. in trying to change the impellers in the pump I noticed the v-belt need changing -- I took the four bolts out of the water pump pulley and the pulley doesn't come off -- what am I doing wrong?
