I'd like to see this with a rubbermade body and a Surron motor. I think that I would have tried to make a wetsuit sleeve exhaust boot and gasket. lol... 🤙🏻

[@Gryffonmd]

Where did you originally get the jet boat

[@Gryffonmd]

⁠@@Zane.Wellnitznah Altis sigma motor

[@Zane.Wellnitz]

​@@Gryffonmd That is true. You know it would be a nice little silent go anywhere boat.⚡

[@eetack]

You need a stomp grate, it would probably have to be hand actuated though. Also have your crew cary a spare assembled pump, maybe two so you can try different pitches to see what works best against the current. Kawis don't like sand and grit. I have rebuilt 4 pumps for 4 different skis from the same customer because he constantly beaches in rocks/sand without a care, or sobriety. Also, when in the shallows, you want to be going as fast as possible at all times, and when it gets really shallow, always keep the boat off the keel. I mean, reaaaaaly lean it hard to one side of the other, as hard as you can without cavitating. That will create a triangle of clearance for the intake, and give you the maximum amount of water under it.

[@justjackfromsc]

Kind of surprised that Ethan wasn’t wearing a helmet.

[@MarineTpt92]

Came here to say this!! One bad tumble away from the forever sleep box. 😬

[@paulmcguire6366]

I agree.....dumb......really dumb!!

[@FalloutBreakbeat]

For sure. We've lost quite a few people to head-to-rock accidents. Schumacher comes to mind.

[@williamsmith169]

I feel like people who haven't endured a lifelong injury don't understand the importance of injury mitigation. One wrong move and you're walking with a cane the rest of your life, at best.

[@zcl812]

He should be. It bothers me to no end when people take needless risks (if youre going to do dangerous sports at least wear protection), and set a bad example for the kids who look up to them. Same goes for PPE in the shop. Nobody looks cool when they're permanently injured or dead.

[@kiwishamoo6494]

In a boat that small, shooting white water, you really REALLY should wear a helmet

[@yz4402]

The driveshaft bearing behind the engine won’t cause cavitation, even if it is leaking. Things that will cause it are: Any whitewater, a bad seal around the outside of your pump (you can use silicone for this if you don’t have a good rubber seal), the impeller to wear ring clearance being too large (likely what happened when it self clearanced), large gouges in the impeller or pump vanes behind the impeller, as well as any small rocks/weeds hung up in the pump, pump tunnel area or on the intake grate. Upgrading your pump to a Solas 12 vane pump will help with the whitewater cavitation! I think you’ve already figured this out, but it overheated and blew the exhaust coupler because cavitation creates low water pressure & lots of air in the pump which makes it so it cannot effectively send water through the cooling lines. Love the content & channel guys!! Great stuff as always.

[@wrenchg3954]

Lmfao i was going to add a comment, about how Ethan should Really be wearing a helmet on this one. And the first comment I read is exactly that. So here's número Dos about protecting that noggin brother. Getting ko'd while navigating through rocky white water. Nothing good will ever come from that. GHP crew always sending it

[@jlucasound]

Many more than two comments! 😄

[@boa2143658709]

I believe he weighed the risks. If you wreck with a helmet it's common knowledge you do not remove that helmet until EMS gets there then they do it a very specific way. If he needs mouth to mouth they could kill or cripple him trying to remove the helmet. Also the helmet itself poses neck damage risk with the way he's bouncing around.

[@PewterQ]

Should know better than that.... No helmet 😂

[@kevinkilz5700]

A helmet for everything else but the mini jet boat! Cmon bro 🤦‍♂️. So sick though.

[@3GingerCats]

Can I suggest having a small Bouy attached to a line inside the boat? so if it gets swamped the bouy floats up and makes it easier to recover the little thing. So here's an idea for you... shove it in a shipping container and head to New Zealand, Queenstown in particular, and run it next to the Shotover jetboat tour boat (one of the largest jet boats) that carry a dozen people up & down the Shotover River. and why not hire some ADV bikes and do an offgrid tour around the place, make a working Holiday out of it & an experience you'll never forget!

[@northwestgaming4049]

Here in oregon they have company that does tours on the Rogue river with these 3 engine jet boats

[@AmIAntiAntianti]

I, as a non paying youtube subscriber, endorse this. Heck yeah

comes off as disingenuous yeah? same sort of thing as perpetually scolding will for being unsafe, and then not wearing a helmet. I don't wanna be that guy, but maybe GHPC folks are gettign a little big-headed? It's kind of just what happens with channels after a few years usually. idk

Rock crawling a mini boat is definitely a new form of Off-roading

I'd just like to suggest a helmet to protect your brain in the event of a miscalculation. Wear a helmet. It could save your life.

[@KSwapTheWorld69]

I have a traumatic brain injury from a wreck where I went out the windshield, I crushed my skull 3 times, and I'm disabled from that 🫤 you only have one brain 🤷🏽

[@chrismorrison3298]

You should see if you could fit it with a nylon skid plate like you do on a dirtbike. It’ll make it slide over the rocks so much better

[@modocroughstock5700]

UHMW is what is used in food processing.. durable as heck

[@tbillington]

Great idea

[@bradendenning1509]

Build a aluminum jet ski

[@jessepitt]

It already has that.

[@cycoholic]

That's why the underside is black, it has nylon armour to help it slide over rocks and to help stop any thing puncturing the hull.

[@jimsworthow531]

the good thing about the mini jet boat in that shallow river is it mulches trout fry and crayfish craylings.

[@pauledlington4122]

Need a river with a bit more water. Suggest you hit up some local kayakers and get their recommendation on where and when there is a good class 2-3 river in your area. Plus wear a helmet next time dude

[@riderfreak]

It seems like a good class 2 ricer, they just need to try when there is more water...

[@ScreamiNarwhals]

I would be the strangest combination of annoyed and excited if I was fishing that river and he came up it with that little monster 😅

[@tenalterna]

[@Sflhunter]

Just think if you had a helmet on you, gotta put the GoPro on your head for way better view than that thing is shaken around on your chest

Don't put any camera (or anything else) on your helmet. That was a major contributor to Michael Schumachers current condition. Hope he's doing well. 😢

"It's obviously broken but we're just going to keep running it." Shortly after: "Why did it stop working?????"

@@goosenotmaverick1156 I question they safety, and sanity of most that try it! Have you seen those rapids? I've rafted the Green, years ago. That was fun and sometimes intense. The Snake, by jet boat looks like a riot. Not sure if it's a riot for me, but DANG!

[@goosenotmaverick1156]

[@ciji6551]

I’ve kayaked white water for decades and I’d have to say you would have had much more fun on a river with more volume. Class 3 would be doable but better flotation and a helmet are recommended. Plus a couple of safety boaters for rescue. There is a great documentary on the first jet boats running rivers in the Himalayas, a much watch.

[@rjc862003]

might be advisable to redesign that drive shaft with a double joint so it can move and not crank its self into the bearing which is likely what killed the bearing

[@xray235]

I think a folding paddle might be something to include in any future boat mods. That way you can always canoe your way back to the dock when the engine ultimately explodes.

[@purplepenguin43]

if you need a boat to follow the tiny jet, you could get one of the heavy duty inflatable jetboats with a 20-50hp outboard jetpump. the bladders conform to and bounce off rocks intead of bending or breaking.

[@vech400]

The old saying “it’ll wear in before it wears out” seams to apply here🤣

[@j.williams560]

It’s been suggested by the locals yall stay out of the Bull going forward. Thanks to your antics, in some areas of the river there are now efforts to close the river to watercraft. Well done. Looks like you pissed off some in the 406.

[@chir0pter]

You should also install one of those shock absorbing seats like they have on military jetboats. I can't imagine that felt good neither on the spine nor the ears

[@technicbuilder6410]

What you experienced was not cavitation but ventilation. When ventilatin underpressure sucks in air from somewhere. While when cavitating underpressure is so high that it boils the water.

[@johnmorgan1629]

Seeing as you had to walk the boat back again, you could've done with that stick you found for Steven. 3rd times a charm.
