I have a 1986 Wellcraft Nova Spyder with twin Mercruiser 350 Magnums and Alpha Drives. My problem stem from fuel delivery. The boat would not start a fault noticed was no fuel being delivered to the carberatur. (Currently has mechanical fuel pumps). I spoke with the previous owner her recommends replacing the mechanical pumps with an Electric pump. I can find the pump he recommends. He states the numbers from the one he has is 40704J08A Carter Pump Part Number 152-875). I checked in Carter's web site to no avail. Is the swap from Mechanical - Electrical on a carberated motor recommened and does anyone have information regarding this pump?
