I will take help where ever I can find it. I know there are a lot of smart people here so speak up. Here is the $100,000 commercial version of what I plan to build.

I have a 215hp supercharged seadoo RXP I will use for thrust. This video shows at 2m47sec a good way to attach it to the rxp:

The swivel is the hard part. Im hoping I can buy a swivel but I may need to make a swivel like they did in this video at 2m02sec:

I have a drawing of his swivel it but I’m hoping I can buy something like this:



Pretty simple I plan to run 5” fire hose to .083 wall aluminum tubing something like this:



I THINK .083 wall aluminum will be enough. With my very limited math skills I think the burst pressure of 5” .083 wall aluminum tubing is 1200psi. I have no idea what kind of psi I will be working with. Does anyone have any ideas?

THAT IS BADDARSE!!!!!!!!

I found out the swivel above wont swivel when its tightened and isnt water proof unless tightened. I guess I going to have to make a swivel like this unless anyone knows where to get a 2.5" "live swivel" for a good price.

That's freaking cool,I like the smaller version from your feet

yea I would imagine under pressure it will have to have torrington bearings like the drawing

I likethe hanging one looks like it will be way more stable

I realy thought the one that attaches to your feet was a great way to break your neck. Im going with the back.

wow thats cool cam

I think the teather needs to be about 4 times as long

that is cool

it'd be real cool if you didnt to drag that boat around.....
