I am changing my blower setup from a B&M 250 to a BDS 871 bllower and they have two different accessory drive pulley one 3V for marine use (5'') and the standard 3V accessory drive pulley that they are bigger arond 6.75'' i believe.

My question is, Can i use the std bigger 3V accessory drive pulley with the Mercruiser fuel/raw water pump ?

Thanks for any advice.

Can we overdrive the Merc Gen 5-6 fuel/raw water pump with bigger dia 3V accessory crank pulley?
