Scarab Transom Mounted freshwater cooling
 

I have an 1997 Scarb with dual 350 Mag's Alpha One' Gen II drives. I am repowering with new 357 engines full freshwater cooling. Not sure weather to use transom mounted freshwater pickups or thru hull pickups and where to mount them. Boat ran up to 70 with 260HP mags, would like will be about same with 357 325HP engines.
Water temp here in 80's

Any help would be great, JP
