Cool. First example that didn't use the two-cycle engine. I see someone suggested switching gears around for more impeller speed. I plan on building a jet boat also. Thanks for posting. I'm always looking at everyone's ideas to try to save myself some missteps.

[@srrings]

good job looks very reliable and fairly simple to operate. that tension screw great idea might want to make a locking device if you don't already have one in mind boats do nothing but vibrate bounce and roll... what a cool set up

[@ronaldhotboy]

Thanks a lot! I hope it is reliable. We should find out in about a month lol. By locking device you mean a way to lock the bolt in place?

[@srrings]

yea something like that.. just something that can help hold the set tension so in doesn't walk down the screw....

[@adirondacklabs1799]

WOW! This is an awesome display of your mechanical design skills. Very nice.

[@ronaldhotboy]

Thanks a lot brother! Most of it was trail and error lol

[@mrnutsy1]

That is a nice, simple design. It looks like to will work without too much trouble. A couple thoughts, if I may: A low profile scoop to help draw the water in better. When you get up to speed, you will have some air mixing in with the water. The scoop will help reduce the 'stall' effect. A 'seaweed' guard to keep the plants from getting into the jet channel. It's not a problem out in the middle of a lake, but near shore you are likely to get into it. When you were testing the engine and the drive, I heard a squeal coming from the drive. The chain looks like it might be a just a little too tight, although it's hard to tell for sure. Great project! It will be fun when you get it launched!

[@ronaldhotboy]

+Mr Nutsy Thanks a lot! She did work! We topped of at about 9mph. So we just have to get a bigger engine and we will be moving. Thanks a lot for the scoop, guard, and chain ideas. The first thing I'm going to work on is the grate to protect the intake. Thank you SO much for your help and thanks for watching!

[@growleym504]

Well done. A few good points raised in other comments. Your youtube peer support group is a valuable tool. I will offer this observation. The sliding engine mount eliminates the usual adjustable idler sprocket, and is very smart thinking, but it leaves the engine itself on a very shaky footing when it should be bolted solidly to the hull stringers due to vibration and torque. it will work, but it might not hold up long. If it starts to rattle itself loose, just remount the engine to a solid base and add an idler on an adjustable arm. It can be a swing arm, or an extend/retract arm, either way. Also it looks like you used a salvaged thruster. Right. No sense reinventing the wheel and it could be a complex and expensive thing to make. But it will be more efficient if the engine and transmission you are using is close in torque and RPM to the engine and transmission that originally powered it. These things tend to have a narrow performance/efficiency band, so I am led to believe. I really love what you are doing and I will be watching your followon videos.

[@ronaldhotboy]

thank you SO MUCH Growley! This information is very helpful and you did an awesome job at delivering your message thoroughly. Everything you've pointed out makes perfect sense and got me reevaluating everything I thought I knew lol. Oce again thanks bro; its people like you that make our projects prosper

[@gasmonkeygarage1129]

i really like that set up for the motor mount, ive never seen anything like that before, one suggestion i may add though maybe try running the exhaust out of the pump aswell like the real jet boats.

[@leesale5832]

Cool project. Just fyi. The jet pumps are set up for 5000 to 6500 rpm. You might want to change the sprockets to more of a 1 to 1 ratio if you can find a sprocket small enough to put on the shaft to match the clutch. Or move the engine forward and lower so that you can direct couple to the shaft. Maybe go with a universal joint shaft to allow the engine to direct drive the pump. Jet skis use an angled motor to line up directly with the pump shaft. Could do away with the clutch since the water acts like a fluid clutch. Another problem will be the hp. Typical ski jet pumps use at least 50hp to drive a pump like that.

[@ronaldhotboy]

Thank you a bunch brother! That has been bothering me since i started this project. I never was sure if this 6.5 hp engine was going to ne enough to push her. I think what im going to do is just use this small engine to test the overall physics of the boat as a whole. After that (if everything holds up) ill upgrade to an actual pwc motor. You are extremely helful and PLEASE if you see anything else that could use improvements im always looking for a better way. Thanks a lot!

[@bilderbobb]

ronaldhotboy I have raced cars of one kind or another, including go karts for 50 years. And I can tell ya, don’t under estimate what you can do with a 6.5 HP engine. For $15 you can turn that 6.5 into 10 HP. For less than a hundred you can turn into 12 HP. That last engine I built was dyno’d at 22.3 HP and turned 10K RPM, and I had around $750 in it. I also noticed you have a shoe type clutch on there. With a disk clutch, like a Bully, you can adjust the stall to hit the power band harder and faster. There is one thing to be EXTREMLY careful of tho. The stock flywheel on any of the clone engines is absolutely dangerous at RMPs higher than 6K. The magnets are glued onto the flywheel and can come off and hit the coil causing the entire side of the engine to explode. Simple solution is to put on an ARC flywheel. I am sure the jet drive will move the boat, just a matter of how fast. This has made me want to build a boat myself.......... thinking about a jet drive tunnel hull.

[@ronaldhotboy]

bilderbobb I would love to get 20hp out of this little engine, but at the same time I dont want to spend $700. Thank you SO much for heads up about those magnets; i had no idea. I said the same thing about the engine and pump; I know its going to move, but the only way to realy find out how much is a true test. You really should build one brother; with all the knowledge and skills you have, it'll turn out bad ass. Thanks a lot brother!

Nice work. Swap those gears round the other way, it'll spin the impellor much faster, also maybe a higher revving twin cylinder engine from a bike could be a better option as the one you have there works at low revs as a jet impellor needs to spin fast to work properly/

[@sideways46]

Thank you for your reply. I went out today, and got the engine tuned, I believe pretty good. I think that old Berkeley pump is worn out, I put in tail shaft bearing, but I can see light thru the impeller and housing, and was told that's not good. Berkeley doesn't even acknowledge the pump on there web site. I was told get a "wear ring" but don't know if it has one or where to find it . The pump was made in 68'&69' for the first Seadoos & I guess a few boats. The only reason I bought the thing as a project was I had never seen a miniature Berkeley before, and thought it was cool. I'll keep you informed if you like. K.C.

[@ronaldhotboy]

Wow brother, I need to check this out, you got my head spinning. I would assume for a 68 or 69 that it would be hard as hell to find parts. Please keep me updated brother! Thanks

[@about2mount]

DODGE makes a nice universal shaft to shaft FLEX coupler and it uses a rubber insert instead of using a chain. It will also stop any vibration noise and allot safer to operate. But using either one add you a guard.

[@ronaldhotboy]

Hahha nice idea for the clutch bell

[@jjr1028]

Srry, I just commented on your last video but what is the black thein before your sprocket and what is the size of the chain and other sprocket you used.

[@ronaldhotboy]

Thats a clutch brother. A couple of people told me that i dont need it because the water will act as one instead. The clutch has its own sprocket (number 35 chain) and the bigger sprocket(number 35 as well) just has a bigger bore(the middle hole for the shaft) and more teeth. The clutch is typically used to prevent your engine from stalling/damaging when a load is added. Check out '1tuffdog', he knows WAY more than I do. Let me know if I can help with anything and thanks for watching brother!

[@bloodsweatandtearsforeverl9833]

You don't need the centrifugal clutch, because you can just start it in the water, but if you want to go faster your going to have to hear it up put a big gear on the engine and small on the axle for the propeller, there's alot less resistance in water verses pushing weight on land

[@ronaldhotboy]

Thanks a lot brother; someone else told me the exact same thing about the clutch. When I install the new engine we will test that theory out for sure

[@definitionofhappiness6134]

[@TheTorkerman]

Awesome job.

[@ronaldhotboy]

Thanks a lot brother!

[@charlesb5007]

for that engine the gearing is probably ideal. If you had a larger engine you'd need to make the pump gear smaller to spin it faster. Ive owned a few jet boats and actually torque is the most important aspect but that engine is going to be too small. It takes alot of torque for the impeller to force water through the exit.. very cool though...good stuff..

[@ronaldhotboy]

+charles b Thanks a lot Charles! Sorry im just seeing your comment. Just so happened to scroll down and seen a bunch of unread comments. You are SO right about the torque issue. Here I have her geared 3:1 which did get me up to 9mph. Well I changed the gearing last week to gain more speed ( 1:1.8) then.....wa....wa....waaaaaaaaaa. lol SHE STALLED! I was only able to give her about 1/8 throttle before she stalled on me. I SO wish I would've seen your comment earlier. Thank you for your help brother!

[@ronaldhotboy]

Thanks a lot brother! I have quite a few videos showing the entire process. I didnt record the pump intake process because I thought that no one would want to see it. I used fiberglass and resin for the pump intake housing. I used clothe hangers to capture the curve. I have no idea about the the RPM nor the GPM.

Delrico Eppes Thanks brother i cant wait neither. DAMN MAN, that would be bad ass! (Doing the evil scientist fingers lol)

[@omarmohamed5120]

Hi bro so your boat has a starring to control directions?

[@gregofili]

Well Done Sir !

[@ronaldhotboy]

Thanks a lot Greg!

[@jeffkennedy8219]

you might scavenge the driveline from one of those cheap scooters that's been laid down too many times for a good price. I've not put much thought behind this idea, so it's up to you to research final drive/ variable ratios that would offer vs the torque numbers you wish to apply. hopefully that gives you some healthy food for thought, rather than a pipe-dream. By the way, that build looks solid and clean! Props to ya, friend!

[@ronaldhotboy]

+Jeff Kennedy Thanks a lot brother, very helpful information!

[@grandroofing1604]

I love it. You are learning as you go. Everything you build from scratch has lots of redoes. However at the end you have something to be proud of. I have a 96 evo harley motor I want to use in my build. I am from Louisiana and built my first boat in high school. 12 ft pirogue. I am not sure whether to use a prop. Or jet drive? Thanks for sharing.

[@ronaldhotboy]

You are so right about that brother; most of what we do is trial and error. I just love testing new theories. With that Harley you should have plenty of torque to push through. WHAT! I'm here in baton rouge! You might be God sent because I was looking to purchase some aluminum for my next boat within a couple of months. I started my build with a prop and rudder in mind but then after talking to a few people I changed the design mid build to jet drive. They both have their draw backs but id rather not have to put up with my prop hitting debris in the water. Thanks for watching brother!

[@Zachatar]

that is awesome keep it up

[@ronaldhotboy]

Thanks a lot brother that really means a lot!

[@baltsosser]

Wood work, motor mounts, fiberglass work, metal work...you hit all of those nice areas of knowledge with this one. I'd love to make something like this. It has an interesting to make. Where did you source the jet boat parts from?

[@ronaldhotboy]

Thank you so much my brother! Its just so soothing to work with different materials. I ordered all of my parts from ebay (95 wetjet duo)

[@chrissyjohnson1937]

great video....

[@ronaldhotboy]

Thanks a lot Chrissy!

[@kylevick8329]

Brilliant Tensioner!!!

[@ronaldhotboy]

Thanks a lot Kyle! Just a little trial and error

[@aaron9250]

GOOD STUFF MAY WANT TO GO WITH 1: 1 ON THE CHAIN ONCE ON THE WATER . LIKE IT

[@ronaldhotboy]

Thanks a lot Aaron! That is exactly what we plan on doing brother (going 1:1) I'm glad you like it bro; thanks for watching!

[@richardpaalan7415]

You could just directly connect it without those gears, it make propeler turn slower

[@Open_Throttle55]

how did you seal the shaft? so your boat doesnt take on any water

[@marbindelacruz1164]

How sis you do the rotator not rotate when not needed to turn.
