    That's a great idea. I'll pick a few up and test it out. Thank you! I thought so too, but it's just a clean spot from me dropping a socket extension through the plug hole to push the piston down while using an endoscope to look at the wash. Hindsight, I should have just turned the coupler.

    Exhaust is an R&D wet pipe, you can see a pic of it in post #17 I would think this might matter as well, the water temps on the rivers up here are really cold compared to lakes down south. Average is mid to low 60s. Here is the current list of parts: 701 62T Case/61X Cyl (Stock porting) 35cc...

    That makes sense, it's a lot of load on it. I just thought the rear cylinder would have been the one acting up more than the front. The other odd thing to me is that nothing mechanical has changed in regards to the engine since the end of last season and now the jetting is much leaner with...

    Made a few changes to the boat for this season. Added a Southern jet Posi-nozzle trim system with an electric actuator to adjust on the fly. It has a level indicator gauge as well. The boat has way better thrust in the corners and tracks better too. It also shoots a 60 foot rooster tail when...

    Rivers are starting to flood out around here. Makes for a lot of fun little side channels. Also found out I don't have the power to push up the high flow in spots, so speed and momentum is the only way through. Scared my buddy pretty good going through some bushes back to the main channel too.

    I think New Zealand is where these little boats originated from, they have tons of crazy rivers out there.

    Intake and exhaust ports were left stock, no additional porting. The builder said it's more reliable that way, which I cannot validate. I will keep that in mind when I get out in the spring to tune again. I'm going to start from scratch with the impeller change.

    Depending what type of rivers you run, a 12ft could be great. The lighter the better if you run out of water and have to push it. The rivers here change throughout the year and some channels are open one day, but closed the next due to flow changes. If you aren't worried about that, I would also...

    Yeah, that's where I bought it all. I'm heading down south later this winter, I'll reach out to them before I head that way. I haven't had a chance to run GPS yet on it and the snow is flying up here now. I'll update next year, although it didn't feel much difference. It needs lots of tuning and...

    It is a very loose feeling as far as handling goes, the back end sort of drifts around corners. Which is actually not a bad thing depending how the river is, because you can keep the pump intake over the deepest part of the river easily. I have ordered a different style of trim nozzle that is...

    Yes sir, same thing as Teflon I believe. Heavy duty stuff! I think I've found a lot of the weak points and put them in the last post. I'll be uploading a video edit of some adventures this summer.

    Part 3: Added a wrap, really easy and only $200 on Amazon Ended up breaking a tine of the intake grate. Resulted in a bunch of bigger rocks getting through and abusing the pump. This was a Solas 12 vein with a SS wear ring and Hooker 9/15. It's pretty banged up, maybe beyond repair. I was...

    Part 2: Added handrails to the windshield. New 1/2" thick Full Width UHMW for bashing rocks. Cane with lots of extra weight for free. Added a soundbar for a UTV, which is useless anytime the engine is running. So it's being removed and a comms setup with tunes is being swapped in...

    I had a good crash mid season and cracked some welds on the hill. Long story short, we spun out and slid backwards into a log jam. Which cracked the steering nozzle, we didn't notice that when we looked. Headed downstream and it blew apart when I tried to turn right. It resulted in the boat not...
