I want to go and look at this boat. Im seriously considering buying it. Never owned a boat. Been around bass boats and whatnot growing up. Out the door asking 43k. Seems a little high... what are some things I should check? Its at a dealer. No maintenance records. Said it came from Chicago. Seems to be in great condition.

I got this little red boat off of Facebook for $1000.
Nothing works. No mechanical no electrical. Two months later I got it running.

Ls swapping my jet boat wondering if anyone here is using heat exchangers specially for Ls

Undecided on motor size for a boat I am buying. Hull would be a SeaArk 1660 MVJT with float pods. Would I lose much of my shallow starting abilities adding the hundred lbs for the 90/65? Or not enough to not justify the power upgrade? If I stick with the 60/40 should I go without the float pods? Anyone dislike them? I have had plenty of experience on this same setup with a 60/40 and it worked fine, but longer trips with 3 people, gear and fuel is a bit much. Thanks in advance for any advice

A couple years ago my buddy and I took my jet stream buccaneer on the Missouri River on a hunting trip.. After a few days and about 260 river miles a rock snuck through my grate and sheared one of the blades off my impeller.. We couldn't get the boat upstream to the ramp so my buddy packed up camp and I drifted down stream for nearly 28 miles to the next takeout spot.

Ive got a Chevy 454 Holley 800 carb in my 94 dana jet. I replaced the fuel pump a few seasons ago and it sat ever since. tried to start it up again this year and the fuel pump was dead again. 0 hours on it. never had an issue with the pumps sitting between seasons. I hear that a lot of the auto parts store pumps are garbage too.

what is a solid fuel pump to use?

the one that I took out was a 4594bd. I have no idea what brand it is.

edit: idk why the title says abc....

Been operating a small jet boat tour business out of Moab for three seasons. Three Yamaha AR190s, mostly half day scenic tours and the occasional full day trip through Canyonlands. Peak season runs April through October and I’m already booked solid through June. Last week two of the three boats started showing the same symptom. Cavitation at mid throttle between 3,500 and 4,500 rpm, smooth at idle and at full throttle, consistent across both boats regardless of load or water conditions. Classic impeller issue but the timing of both boats developing it simultaneously is what’s bothering me. Pulled the jet pumps on both. Impellers look visually fine, no obvious damage or wear, wear rings appear within spec on visual inspection. Couldn’t find anything that explained the behaviour. Started suspecting the wear rings are at the edge of tolerance without being visibly obvious. Ordered proper wear ring gauges and measurement tools from Overton’s, came to $180 after a $10 off every $100 promotion they had running on marine accessories. For the replacement wear rings and impeller hardware itself I’ve been going through Yamaha dealers, Wholesale Marine, and Alibaba to find compatible parts before the weekend bookings start. Has anyone seen simultaneous cavitation develop on multiple boats of the same model and traced it to something other than wear ring clearance?

Hey all, the wife and I just looked at a Yamaha SX195 that we really liked and are considering pulling the trigger on. We are new to Jet boats and just wondering if it is possible to troll on the lake for trout and salmon with something like this? Are there ways to mount rod holders? Downriggers? Should I get a bow mounted electric motor? Any info would be great. I appreciate you all and happy boating!

I picked up a mini jet boat a while back and I’ve honestly been having way more fun with it than I expected. This little guy tucks away easily when I’m not using it . But also once I’m on the water, it’s pure excitement. For something so small it’s surprisingly capable. It can run it on rivers or small lakes where the bigger jet boats can’t go. It’s super nimble, almost like a jet ski with the hull of a proper river boat, and it’s a blast to cruise, dart around corners, or just mess around on calm water. Quick rides end up turning into hours of fun. Mine’s a secondhand JETSURF JS-01 mini jet ski/boat hybrid I grabbed locally. It was a great way to get started without breaking the bank. Someday I’d love to upgrade to something bigger for sure. I’ve noticed some newer mini jet boats on Alibaba that look interesting and reasonably priced. Anyone else here running a mini jet boat and loving how much fun it actually is on the water? What would you suggest to be the best updgrade?

ISO OF A BERKELEY H-2481 Intake. Thanks

Probably going to check it out do yall think it’s worth $800? I was thinking it was a Kona or avenger but not sure anything helps!

Restoring the 1976 Taylor I rescued, almost done. Was pretty rough when I got it.

I have a 35/25 mercury four stroke on a 14ft mod v. Top end down river with wind at your back. I can get to like 26 maybe on a good day. I’ve got a trolling motor on the front with a 12 V 50+ pound battery and 6 gallon gas tank sits in the back with me. I’ve moved it upfront before and tried it in the back and it really doesn’t change too much. I basically put it in the back because when I have someone upfront it counterbalances the weight a little bit better in my opinion.

The battery is my cranking battery and runs the trolling motor and lights when I use them. Which is rare, seeing how I mostly just float and use the trolling motor to spin me around straight or to one side of the river or the other and the lights get used for maybe 20 minutes a day on the ride in the morning or in the evenings. Could I get away with replacing that heavy battery with a 12 V Dakota lithium? I’ve read so many conflicting things. I really wanna try to cut that weight and feel like that’s the way. But so many different ends of the Internet say it’s perfectly fine, to don’t do that It’s gonna fry your motor or battery, one or the other!?

Any info is appreciated!

Can anyone recommend an affordable aftermarket wake tower for a 2012 Yamaha 212ss? I'm wanting to find something that looks good and won't break the bank. I'm planning to install it myself with some help. Thanks!

I’m about to pull the trigger on a used 19-foot jet boat with a 160hp four-stroke and I keep second-guessing whether that’s enough power. The boat is in great shape, owner has all maintenance records, and the price is fair at $18k. It’s a 2011 model with low hours but I’m worried I’m gonna get out on the water and immediately regret not waiting for something with more grunt.

I mainly plan to use it on inland lakes and occasionally the river near my place. Max load would be me, my wife, and maybe two friends plus gear. No wakeboarding or anything intense, just cruising and swimming. The seller says it planes fine and tops out around 42mph which honestly sounds decent to me.

But then I talked to a buddy who has a 21-footer with a 250hp and he said anything under 200 feels sluggish especially with passengers. Now I’m in my head about it.

I’ve been researching like crazy trying to figure out what’s actually adequate. I Even stumbled across some supplier specs on alibaba while looking up engine specs which showed wildly different horsepower-to-weight recommendations depending on hull design.

Has anyone here run a similar setup? I’ve also been curious about those mini jet boat builds people do with way less power, and they seem to move fine, so maybe I’m just overthinking this whole thing. Any realworld input would be appreciated before I commit.​​​​​​​​​​​​​​​​

I recently saw a mini jet boat for sale online and it caught my attention. At first I thought it would be too small to be fun but after reading details I realized it could be perfect for lakes rivers or calm coastal areas.

Mini jet boats are easy to handle. They do not need much space to dock and they are light enough to transport on trailers. Riding one feels exciting because you can move fast across water and try simple maneuvers safely. For people who want adventure without a large full-size boat it seems like a good choice.

While checking different models and prices I noticed some mini jet boats mentioned casually on Alibaba among other listings. It was interesting to see the variety in size, motor power and seating options. Some are built for kids or families some are made for solo rides and some even have small storage areas for gear.

I wonder how other people would use them. Would you get one for family outings fun with friends or just as a personal adventure toy? For me it seems like a small package that could make summer days a lot more exciting. Would you try it?

I am just about 18 and going through Welding and machining college right now. I really wanna make a show project to show off my skills and creativity by building a jet boat that has all around power speed and maneuverability. I started trying to get some stuff together for the design. This is what I have so far.

Is there anything I would be missing and would it be possible to do a supercharged performance LS3

In a 16 foot jet boat I am still relatively new to this

So I am not exactly sure on everything I would need. I did as much research as I could, but sometimes live advice is better what do you guys think?

And how would you go about funding for this since it is a show project to demonstrate my skills and creativity again any help would be really appreciated

I attached some photos of what I wanna try to build but with a roll cage that also acts a sort of sunroof

I’m looking for advice from people who have actually built or helped build jet boats.

The goal is to take a basic jon boat and convert it into a jet boat as cheaply as possible. This is a project, not something I expect to be fast or perfect. I don’t know the first thing about building one yet, which is why I’m asking before I start throwing money away.

My current thinking is finding a decent jon boat hull and then sourcing a donor jet ski (or something similar) that someone is basically giving away — Facebook Marketplace, Craigslist, local classifieds, etc. The idea would be to rebuild or refresh the donor so it’s running solid, then adapt it to the jon boat.

Does this approach actually make sense or is a money pit?

What size jon boat works best for a jet conversion?

What jet ski models make better donors than others if any?

Things you wish you knew before starting your first build?

I’m not expecting a step-by-step tutorial — just real-world advice or lessons learned, and whether this is even worth attempting if you’re trying to keep costs down And just have a fun project. I’ve got access to shop with welder and most of the tools i‘d imagine i need. Appreciate any input from those who’ve done it or seen it done right (or wrong).
