We are building two mini jet boats to run in super skinny water up here in Alaska. Access to so many areas with shallow water is normally done with air boats and hovercraft. The mini's are now a high performance option for us up here. Problem is most parts have to be custom built or bought from New Zealand or Canada. New Zealand is way ahead of the mini jet boat game and the states are starting to catch on.

We started this project in the spring and had to take a couple months off this summer. Now we are back at it.
Picked up two Honda Aquatrax f15 turbo jet skis and stripped them down. We will use the motor, pump and electronics as a donor for our mini. We bought untested plans from a guy in Canada and ended up scrapping most of it after being cut out and test fitted. Was a costly mistake. This is our first boat build and are learning a ton and making mistakes along the way. Luckily we know a few boat builders who have helped us out as we go.

These will give us access to hunting, fishing and gold mining ground that are otherwise half impossible to get to. My buddy is way ahead of me as I was gone all summer mining but now the build continues.

First two pics here are of guys in Alaska with minis. With full running 1/2" UHMW on top of a 1/4" bottom they can run over almost anything and will run in just inches of water.

We built a leaf brake to bend most of the things we need.

Brake ended up being able to bend 5' long 1/8" 5052

Bottoms were cut and bent locally

Thanks guys! Finished welding in the stringers and intake base. Pulled the boat outside and flipped it. Time to weld up everything on the bottom, make a ride plate, weld up some bigger full running chines and install 1/2" UHMW (plastic bottom).

Those NZ guys are awesome! Here is one of my favorite videos from NZ
This just gave me a massive panic attack. What type of intake grate are these boats typically running? I can't even fathom running across gravel bars like these guys did

Is that a jib(boom) that's mounted to the front of the Toyota? Is it powered by the winch? If so thats bad ass!
Killer build you have going. You got mad skill.

Yep. It's my buddy's. He mostly uses it for hauling logs for the saw mill but it worked sweet for flipping the boat. Thanks!

The guys in NZ run a hardened steel grate. We run hardened steal stomp grates. Wear rings and impellers take a beating and we keep spares with us.

So is this a fishing boat? It would sure suck to be fishing a remote river and have some guy come blasting up in one of those things like that guy in in NZ is doing! Especially in AK where the fish are spawning on those gravel bars.....

You got a point. Maybe I should stop building my boat and sit in front of my tv so I don't bother anybody. And all gravel bars are spawning grounds so no boats should be allowed anywhere in the AK. Give me a break guy

Who ended up doing the cutting? NZ has so many sick designs....I've been kicking the idea of getting the cut files and having Alaska Copper do the cutting on a 5.5 meter half-cab but so hard to to get pricing without the cut files in hand. Are you doing a windshield?
What a great idea to access some of those remote areas to open up for panning or whatever method suits your fancy.
