Has anybody figured out a way to put a seawater pump with the mechanical fuel pump boss on a Gen VI engine and make it work with the serpentine belt setup on a 502 mag?

anybody???

Don't know if it helps, but I upgraded my 454's to serpentine belts last year. The seawater pumps with the fuel pump boss had the same bolt battern as the pump without the fuel pump provision. They bolted into the same bracket. All I had to do was make up fuel lines to account for the different final position of the pump (about 2" closer to the block).

Did you replace the pully on your original seawater pump with a serpentine pully or did you change to a different seawater pump altogether? Was the swap done with all Mercury parts? Thanks for the input.
