You definitely do NOT want to use an automotive fuel pump in a boat.
Marine-rated fuel pumps have double-diaphragms and other design features to

You may want to consider switching to an electric fuel pump that matches the

fuel pump specs for your engine as it would enable you to put an inexpensive

cover where the mechanical pump was located and switch to an easy to a
potentially less expensive solution. I found an electric pump that matched
the specs for my Buick 300 V8 (Skylark and Johnson Surfer engine) at
Autozone. If you prefer mechanical you could purchase an aftermarket
mechanical that meets your specs (more specifically, specs of Auto with
equivalent engine) even more inexpensively; ~$20 range. Autozone, Pep Boys,

Napa...will all likely have appropriate choices. Good luck!
