You should only have to match the wire guage of the leads on your pump
for your wiring.

I will probably go up one wire guage due to the long run from the
battery that will be on the floor of the bow. My reason for getting
this pump is reading David Pascoes advice on the topic.

You can go up a gauge; but, there's really no reason to do so. The
leads will be rated for the load. What you'll generally run into on
considerable wire lengths is a nominal increase in resistance. Are
your leads 16awg? 14 awg would work. Where persons can get into
trouble is going with smaller awg sizes.

When you think about it, that's really only a gallon/second.

This is the one you really want:

I'm thinking about getting a couple of them for our trawler before we
head down to the islands next winter.

That is pretty good capacity. You can't pour it out of a milk jug that
fast.

come to think of it, you can't dump it out of a pitcher that fast.

That's a lot of water!

Your absolutely correct that going to a smaller wire size is what gets
most people into trouble. However, I wouldn't go with anything
smaller than 12ga, and 10ga would be better.

That pump is ratted at 15.5 amps @ 12vdc, and 20 amps @ 13.6vdc.
Basing on a 25 foot run or wire, and depending on how you come at it,
the wire resistance of the smaller 14-16ga wire could have you
dropping 3 - 4 volts down the wire. The pump will not work nearly as
well when it's only getting 9 - 10 volts.

At least with the 12 or 10ga wire, you're reducing the copper loss
down to 1 - 2 volts, and the pump will thank you.

Take a look at http://www.powerstream.com/Wire_Size.htm At the bottom
of the page is a calculator that will let you plug in the voltage,
current, length and wire size, and will tell you the copper loss and
end voltage.

Good luck!

Fully tinned or aluminum? Quite often persons will mistake tinned
copper for aluminum and aluminum for tinned copper. Generally welding
cable will have a straight copper construction. Too, the higher MCM,
i.e. 2/0, building wires like THHN will often be of an aluminum
construction. These are typical constructions though. There are
non-standard constructions out there.

True, but THHN is not spec'd to be used in a low-voltage boat wiring
project. My undestanding is that it, by definition, is a copper wire
that is rated for residential and commercial building, to be installed
in conduit or raceways. There certainly is aluminum equivalent out
there and lots of people use it to reduce cost, but it's not supposed
to be designated THHN. Also is pretty inflexible.
