JETSKI-JON BOAT (JET-JON)

Log in or Sign up. Boat Design Net. Pretty self explanatory As a one-off, properly done, it is obviously not going to be a practical proposition. Unless there is some peculiar requirement that existing product does Diy Jet Drive Jon Boat Review Diy Jet Drive Jon Boat Review not meet. Which seems unlikely. Mr EfficiencyMay 13, I guess that would depend on your definition of feasible. You could put a prop inside a pipe, build Diy Jet Drive Jon Boat Review a steering nozzle on the back, include a thrust bearing and your DIY jet Diy Jet Drive Jon Boat Review would move a boat.

If this is your definition of feasible, then certainly you could DIY a jet. If your definition of "feasible" is to build an Diy Jet Drive Jon Boat Review efficient DIY jet, efficient in this case being input horsepower to effective thrust, Diy Jet Drive Jon Boat Review Diy Jet Drive Jon Boat Review then the answer is "not likely" Your comment that its not a really complicated machine is quite far off the mark. The shape of the inlet is Diy Jet Drive Jon Boat Review critical to reduce turbulence and ensure as far as practical that the water flow reaches the entire inlet area of the impeller.

The shape of the impeller Diy Jet Drive Jon Boat Review vanes is critical for horsepower input and load and the pressure that you are Diy Jet Drive Jon Boat Review trying to build in the downside bowl to increase velocity to optimize thrust.Diy Jet Drive Jon Boat Review

A guy who jots drawings diy jet drive jon boat review on a table napkin will not diy jet drive jon boat review this profile, computors are used. Then there is the set of stators, for increase thrust recovery, another computer aided design project. Cavitation calculations and limits are critical for jets and the vane design.

Then the easier stuff, thrust bearings, lubrication, nozzle sizing, steering, vibration, etc all put building an efficient jet for a DIYer quite far out of reach. BarryMay 13, Every jet drive started as a prototype. However, considering your previous Diy Jet Drive Jon Boat Review posts, I don't think you have the expertise and equipment to do Diy Jet Drive Jon Boat Review it. To start with, jets are run by impellers not propellers.

There is a lot of advanced engineering involved in the design. Not just on the shape and Diy Jet Drive Jon Boat Review size, but also the materials. A DIY jet drive would be like a Diy Jet Drive Jon Boat Review steam powered outboard. You could probably do it, and it would make an interesting Diy Jet Drive Jon Boat Review conversation piece, but you shouldn't expect anything that performs within an order of magnitude of a professionally designed and manufactured drive.

Emerson WhiteJan 18, Hi, Few Diy Jet Drive Jon Boat Review diy jet drive jon boat review to take into consideration: First of all DIY jet is feasible if you have some knowledge, funds and the impeller size is not very large. The major risk, which is not present in DIY open propeller, is that if your waterjet duct is inside the boat hull, a break down of a component can lead into a fatal leak. By saying Diy Jet Drive Jon Boat Review this, a safer approach could be something similar to Alamarin-Jetwhere the jet is mainly outside the hull.

About the geometry: impeller, stator, nozzle, deflector, intake are the components that require some knowledge in hydrodynamics. Sand-casting would be the way to go when manufacturing these components maybe up to hp?

I know one case of a successful DIY waterjet but if you really are up for diy jet drive jon boat review challenge, maybe try to acquire a used jet from somewhere Diy Jet Jon Review Boat Drive and do some reverse engineering. Ben LandgrenJul 20, To add one more thing: if you successfully manage to build a jet drive that actually works at some stage, without proper hydrodynamic design, cavitation will most likely Diy Jon Boat Stereo Game occur, which will destroy your components pretty fast.

The open propeller cavitation does damage usually only to the propeller, but in waterjet case cavitation can typically occur in the inlet, impeller and Jon Review Drive Boat Jet Diy stator. Is this like what you're thinking OP? And to Ben, any thoughts on the design they've been working on? I want to stick it inside of a Stand Up Paddleboard eventually and I'd rather not have it self-deconstruct while I'm riding it!

EldiasJul 25, Hi Eldias, I got an assignment from a client waterjet manufacturer in the end of last year to scale Diy Jet Drive Jon Boat Review down one diy jet drive jon boat review their jets todesign the shaft line and bearing assembly, print the parts and conduct diy jet drive jon boat review pull tests.

I just finished these tests diy jet drive jon boat review Newcastle University towing tank few weeks. Impeller, stator and duct diy jet drive jon boat review printed of ABS and the shaft was naturally stainless steel. Tests Diy Jet Drive Jon Boat Review were run from to rpm in bollard pull condition and maximum thrust of Diy Jet Drive Jon Boat Review 50N was achieved.

Despite the epoxy coating, the impeller blades had most probably deflected under the loading, so I would suggest to use another material than ABS for impeller or add some reinforcing fibers around the blades. High blade loading is a thing for bollard pull though and if craft is in forward speed the blade loading is typically smaller.

Hope this helps. Ben LandgrenJul 26, I appreciate the input Ben! I'd suspected I'd need to glass reinforce the parts and was considering having the major pieces printed by Shapeways in nylon with a brass impeller. Im concerned about cavitation damage so I'll wait for Diy Jet Drive Jon Boat Review Sundogz to run through his testing before I have anything.

EldiasJul 26, I Drive Jon Diy Boat Review Jet Diy Jet Drive Jon Boat Review ran a couple different twin jet setups in the military. Prop was bronze and housing was cast aluminum.

When new, the tips of the blades were. In dirty water, like most river water, the housings wore quickly. As the clearance got bigger, the top speed went.

Top speed was originally about 42 knots but Drive Review Diy Jet Jon Boat went down to 35 knots after several months of continuous use. I don't Diy Jet Drive Jon Boat Review see why you couldn't make one, but I'd copy an existing design.

The jets I ran had about a 12" x 18" opening in the bottom with like a flat bar grill to stop big things from getting Diy Jet Drive Jon Boat Review Diy Jet Drive Jon Boat Review into the jet. The intake runner needs to be smooth and transition to the prop in a gentle diy jet drive jon boat review. LepkeMar 5, Hello Diy Jet Drive Jon Boat Review I designed one for electric power.

Seems my daughter has quite some fun. Toto44Nov 29, You must log in or sign up to reply. Show Ignored Content. Similar Threads. Can anybody identify this jet?

Inboard jets are more efficient, Diy Jet Drive Jon Boat Review but come with other problems, including weight.
