    Do these small outboards have fuel pumps strong enough to pull 3 ft. of head? Specifically in my case the Mercury Pro Kicker EFI 9.9/15.

    Thanks!

    When the outboard is in use, the pump will be about 1 ft above the waterline. How deep is the tank below the waterline?

    The pump is about 21 inches above the water line. One of the possible locations for enclosing a below deck gas tank will put the pickup tube pretty close to 3 ft of head, but probably more like 32 inches. I rounded up to be safe. I don't want issues as the tank gets closer to empty.

    Sure it will pump, think of a 25" engine pumping from a vee hulls tank in the floor.
