Jet Jon Boat

If you really think the load is that much increased shouldn't you be looking for a lower pitch impeller for all around better performance and a similar load on the engine at any given rpm?

Any pics of it running. That thing will be a great shallow water river runner, cruisin the backwaters of the mighty Miss!!!

Looks Well Built !!!!!!

Otherwise it is this:

Hold my beer and watch this !!!!!!!!!

It normally ends bad.

You must install cup holders.

i just spent some time googling home built and manufactured jet jon boats. one manufacturer has a pretty basic looking boat 21' starting at 34 grand... the home builds are pretty cool . funny google image search has the yellow fiberglass ski boat with the pressure treated tower ,that boat is everywhere

Yes, a guy could overdo it:

That's freaking awesome haha. I've heard of a few of those running around.

The worst I encountered was a 16' Cruiser Inc with a Merc 6 on it. It too would chine walk and then it would hook a chine. The worst of it's handling was in turns. It would not lean into a turn but would lean away from the turn. Then it would hook the chine and the boat would almost flip. Several passengers with a unsuspecting driver at the helm were thrown out of that boat.

Justin,
You can be the test driver to do 80 in a flat bottom jon boat! Read up on "hooking a chine".

Chris,
I like the present seat mount!

The project is looking great!

Quick update on my winter project -

I bought a 1648 Alumacraft from a fire dept - 10 years old but only saw water 3 times & never rescued anyone.

I also found a '95 polaris 750 jet ski for $500, seller ditching it because the pump shaft seal was broken (was easy fix). In the paper work that he gave me, were $1500 reciepts for the engine rebuild! It has great compression!

Here is the jet ski hull now, I added flanges (US Composite resin, of course) that will glue into the big hole that I will cut in the jon boat hull. Will use 5200 + screws to attach it. In addition, it will bolt to the aluminum stringers to take the propusion forces.



I will have 2 seats mounted just in front of the bench. The steering will be a joystick (like an airboat). The stick will be on center so you will be able to drive from either seat.

I probably will also put in a bench seat up front.

I came up with a way to mount the gas tank at the rear port corner (under the old bench seat) - that way the filler neck will be at deck level. It took quite a bit of work to get it shoehorned in there.

I have plans for the dog house, but hard to describe in words. I'll put in a floor & side walls too.

I have studied the USCG boat builders guide & will be in compliance. However, they said no inspection is required on a homebuild.

I should have the engine in by end of the month. I'll post more pictures then.

Let me start off with this Chris,not happening with out pictures. That said looks like a real Red Green project. Is Iowa different than say Illinois? You register the boat if you decide one day to remove your 10hp Honda and put on a 25 Merc you don't reregister the boat right? So you went a little overboard on the hp when you changed your "fishing" motor

I know boston whaler has made something resembling these it seems the carolina skiff hull would be pretty conducive to a jet drive .

Hmmm, sounds like something worthy of me checking into. I'd assume its weed tolerance is pretty limited? I'm always in search of shallow draft boats.
