Are you trying to pick up the water from the drive, or are you going to use a separate external pickup?

Why do you want to do this? The belt driven bravo style pump does flow more, but the alpha pump should be adequate.
If you do this you need to take the impeller out of the drive. Also the hose from the transom to the thermostat housing is soft and will collapse under the suction from the belt driven pump and will need to be replaced with a reinforced type. This advice is from personal experience of doing this.

the top of the impeller housing is sealed with the impeller.you remove it and you will suck air in there when on plane as it would rise above the surface. both hoses. the one inside transom assy and the one from transom to thermo housing will collapse under suction. the bottom of impeller housing has 2 small holes for pump inlet-outlet. will cause flow restriction. every single thing about the alpha water path will not work as a suction input for a bravo or other engine mounted pump. the TRS has no water flowing thru upper housing. they handle lots more power than alphas. if you want to do this use a hull water pick up and put a shower on the alpha upper.

Many late model v6 alpha repowers are set up like this. Cruisers that were inboards or originally had through hull water pickups that were refit with late model powertrains. I know quite a few people with them and this is how the package came from merc
