If Guzzi could put together something like this, you'd think they could make a boat.

Id seriously thought of taking my semi-v jon boat and mounting a v7 in
it. I was going to shroud the engine, and then mount a 55a. VW bug
alternator on top of the engine and do riddance of the 15a Marelli
generator. Thus allowing me to use an electric fan to cool the engine.

Then get rescue a 'trash pump' from a clapped out PWC, hook it up to a
steering stick and have at it.

Hopefully this would be the end result... sort of (skip vid to 1:01)

I thought about just using the whole PWC power plant and pump.

The problem is weight so you would almost need a custom built jon
boat.
OTOH they do make a jet ski based RIBs that get you top a similar idea
off the rack.

This is just one type

The sheriff played with one here for a year or so but I never saw it
again and I live in the place where it would be most useful so I guess
it wasn't that good for them. It was supposed to run in a few inches
of water but the problem with a jet is when it does run aground, that
is where you are, until you get the mud out of the intake.
That usually involves getting out and bouncing it up and down in a
couple feet of water until you get the pump unplugged enough to prime.

Friend of mine Odwil has build a couple of jet ski powered jetboats. Runs
really shallow water. Problem with jets is grass more than mud. They make
a stomp grate for a lot of jets. Basically let's the grate bars move as
two sets and you can press down the lever and every other bar separates.
