i know that all the bell housings, flywheels, clutch plates, ignition and manifolds will just swap straight over but was thinking about the volvo raw water pumps and if i could use them instead of the impeller on my alpha drives? is this possible and what are the pro's and con's of raw water pumps?
thanks

It is the way to go. Remove the impeller from the drive, blank the water inlet into the boat then run a transom pickup to the engine mounted waterpump.
Better flow, bigger impeller which is now servicable from within the boat.
I have the same setup with Bravo 1 Drives and 383ci motors.
