I don't have a cut off or seacock that I can find.

What sort of boat is this that it doesn't have a cut-off for the raw water
intake? Yeesh, that's crazy.

Also consider an electric fuel pump. If the replacement of the mechanical
one is prohibitively expensive (or difficult) you may be able to get by
with
an electric one. If only until you get the boat out of the water so you
can
replace the mechanical one properly. If you can find out the proper flow
rate you ought to be able to use an automotive electric fuel pump to
handle
it.

And there are inline pressure regulators for fuel lines.
