Crazy idea

Could have multiple impellers which go into smaller diameter exhaust tubing which increases the force? 

Multiple stages of impellers can improve pump performance....that's why they use that setup in many industrial applications, but the loss of efficiency will be your enemy.   

Think about adding some gears like on a 21 speed mountain bike to help out.  Just realize you'll have to pedal like a madman to go against the current

Manually powered pumps wouldn't work in a lot of places.  The slightest weed sucked into the intake would have you all choked up.   

The lower Yakima River and Columbia from Richland down are essentially death on jet pumps from August until November due to Eurasian Milfoil.    Jet boats that attempt these areas spend more time cleaning out intake grates, impeller housings, and outlet nozzles than they do boating.   They can avoid the worst of it by staying in 15'+ of water, or in fast moving water that keeps the weeds flat against the bottom, but even then the large rafts of the stuff that break loose and float down are still hell on pumps. 

Cool idea for a yak, but I could see myself scuttling one out of pure frustration after cleaning out the jet for the umpteenth time before even getting to my fishing hole.   

I think you need to get a utility patent on the idea and then trudge it around to some manufacturers.  They've got the R&D resources.

If I was looking for a small powered craft, I'd go with the modified jet ski option.  There's a guy on a different forum that has used one for years.  A big 3 seat model with a windshield, extra fuel storage, rack on the back for a cooler and tackle boxes.  Gets you there fast and is plenty stable.

A regular boat is not an option for me yet and the modified jet ski was what I dreamed about before I ever considered kayak fishing.

Also with a powered kayak, the motor would likely be behind you and it would be near impossible to safely reach to repair if it failed on the water.  I don't imagine any of those would paddle very well either.

A professional patent search and feasibility from a patent attorney costs a few grand before you truly know if the idea is even available.

At the same time you can file a provisional patent on something that would never qualify and advertise it as "patent pending", for 12 months...

Thats a good idea. I will do some research on provisional patents tonight and possibly apply. Though I have zero idea where to start in terms of pitching it to large companies. But its worth a shot, and i really have nothing to lose.

The first thing you need to do is try to develop a water jet kayak which is powered by a foot-powered pump system.  Until you develop the system, you don't have anything to try to patent, and unless the system includes new concepts, you aren't entitled to patent it.  But more importantly, if the system doesn't work well, it isn't worth spending money attempting to patent it.

Wow .... anyone else notice that pointless treads drag on indefinitely during the winter?

You also start important timelines when you apply. Not just beating others to it, but losing it where you otherwise wouldn't.

If you don't get it done in a year, and don't get/file the full patent, and it's provisional, it becomes public record and anyone can file a patent on it.

Its an entire industry to copy a product, get the "patent pending tagline" for $125, run a marketing campaign, profit, get sued (takes a long time), dissolve the company, repeat. 

Amen, Bill.

Drawings, even sketches, are accepted.  Working models aren't required.

Not sure it's worth your time, but if you think it has legs, take it out for a walk and see where it takes you.

If it's a pointless thread, it's not harming anyone as far as I can tell, and heck, I wonder what people thought the first time someone said "Hey!  Let's build a boat out of a Tupperware!"   

fun to watch, couldn't pay me enough to do it.

no thank you -

That Nehalem bar is friggin scary place. Great spot for inshore halibut if you have the cojones though.

Last year was the first time those guys did tuna from their jetskis. With the water temps already looking warmer than last year I bet they will have another great year for jetski tuna.

Wow, see, I'm looking for how I can "pay my way to do it".

I've been mulling the Waverunner idea around for a couple years since watching some guys near the Gulf and another out in Hawaii on YouTube.. But I couldn't find any of my friends that would venture out with me. Now that I know others are as crazy as I am, and live in the same state... I'm looking into it again.

We'll see, hopefully my wife doesn't get our money's worth out of the life insurance policy.

Does anyone know a place that rents waverunners, around tuna season?

I think this was said in jest and certainly not to rain on the kayak angling parade but if you have a policy, you might want to check if kayaking is an exemption like sky-diving is on some policies.   

Of course a gopro with a floatie would probably be more valuable to your wife than any insurance policy if they recovered it after an Orca or the "landlord" eats Ya.
