Fuel pump

[kats eye]

I have 7.4 carberated mercurser I want to replace my macanical fuel pumps with electric ones does any one know the GPH and pressure I need

This is what I used on my 7.4 big block crusader engine when I did mine. I believe the pressure is between 4-7 lbs. No more than that.

Any minute I expect Sandy or Charlie to come along. I believe Mike is right because your motors are carb'ed. Fuel injection is an entirely different animal.
Make sure you have a regulated pump or an explosion proof pump and regulator.
