Rideable Electric Speed Boat Build - PART 1

We are going to build a rideable electric speed boat and in today's video I am modifying a gas outboard motor to fully electric.

Yes, the rumours are true. I started a review channel: www.youtube.com/@rclifeonreviews

[@shreyas3479]

Subbed!

[@kittyztigerz]

why not you use original outboard turning bracket was on it because it reduce headaches of other idea of 3d printers breaking and you can use it make bracket attached to pontoon boat and still use that original water pump inside lower shaft just need new impeller for it and come up to motor just need 90 bend to esc

[@TheHappinessOfThePursuit]

My first video of his, i am very impressed with this. What clear thinking speaking and video editing. He deserves his following, subbed for life! ❤😊

Congrats

[@AntiVaganza]

​@@kittyztigerz Cuz he is hack and more and more so as times go on strangely. A hack with a gazillion followers, that is. So, perhaps a hack with a smart plan to stay hacky for the masses. He seeminly hates doing research so he often makes weird decisions like these. His new bracket also has its pivot point further ahead than it ever needed to be. Maybe not an issue with this power, but still, it's hacky AF and I wonder if he ever considered it's geometry and the consequences of changing it. Also, no coupler between the motor and the shaft. He is likely going to wear out the bearings in that motor way faster than they should. Then again, by then, he is on to the next video. I mean, he is not stupid, probably not even lazy. It just puzzles me how many times he insists on making mistakes 15-30mins of research would have avoided. E.g. he yet has to figure out how to 3D print waterproof parts (enclosures and such) when the RC Yacht community figured it out 4-5 years ago. Or to start using proper o-rings when the two combined would likely have solved all the issues he always has with leaks in his electronics compartments on watercraft. But he gets shit done, he is entertaining and makes a living and the subs think it's all amazing. So, it's all good:)

[@JohnUllrey]

I kept wondering when he was going to drop the whole outboard motor into the lake and then have to break out the snorkeling gear.

[@thebudgetgamer8987]

You should have used the original mounting bracket for the outboard engine as it serves as steering pivot

[@Druain]

And the built in watter pump for cooling. So much extra work with this build😅

[@oneeyedude20]

I was dumbfounded that he didn't use the original water pump nor steering assembly

[@jaketus]

I think you should use semi-flexible coupler between the engine and drive shafts, just in case they aren't perfectly aligned (and they never are), which might destroy bearings in the long run.

[@stefafets2]

I think you are right, however, the 3d printed mount probably allows for enough flex for the bearings to not be under a terribly uneven load

[@Drxxx]

❤❤❤

[@dfgaJK]

Why not use the original motor's pivot? Why 3d print a new one?

[@rocketeerz9]

Hello! Love your channel! FYI, the bottom end of the outboard motor should have some gear oil inside. You may want to check that its still there or you could risk burning up the gears and bearings. There should be a drain bung and a fill port that unscrew and may help efficiency if you use a lighter weight oil.

[@jimix321]

At 50v and 33kv you are at 1600rpm and with the reduction you'll have about 850rpm at the propeller. With that outboard lower unit you are forced to use a small prop so you will be grossly underproped. It would be wise to either increase your battery voltage, change the reduction ratio or even ditch the outboard and build the boat with an inboard engine configuration, which will be way more efficient allowing you to use a direct drive and a way larger propeller.

[@GoldenCroc]

Oh, only 1600 rpm? Yeah that wont be close to enough if he wants to go fast. Dont know how you mean its more efficient though, that depends a lot on how it transfers the power, so it can be either way. Propshafts create a lot of drag...

[@Drxxx]

[@Simon-dm8zv]

@@jotham123 Correct. There is no need to make prototypes if their only purpose is to check something that could have been done with a few simple calculations.

[@Hybert_]

You really should get into bending metal to stop printing 10 cm thick plastic XD Great video

[@grastmast]

0:50 Yes, you are definitely saving the planet with that plastic and batteries. congratulations, good job.

[@AntonMakesStuff]

Cool, will be very exciting to follow this! Regarding the cavitation: there might be holes or tubes going from the underwater parts to where the old motor was, this is for exausts and maybe water cooling. It might be that the propeller is sucking air down through these tubes, that happened for me when I did a conversion :)

[@jimix321]

You are right, that's air being sucked from the old exhaust system. But that isn't cavitation (at these rpm and propeller size it is very unlikely), if it was afecting the propeller (reducing the effective pitch) it would be ventilation but you can clearly see it is produced just a few inches behind the propeller so it shouldn't be having any effect on the propeller. In a combustion engine it has the purpose of unloading the propeller at low rpm and low speed by injecting "high" pressure exhaust gases that unload the propeller (as they are forced not induced) and when the speed is sufficiently high they can't expand in the direction of the prop so the stop having any effect. It helps quite a bit mainly for getting into plane.

[@AntonMakesStuff]

@@jimix321 That is very interesting, thanks for explaining :) I don't really get what you mean with "unload the propeller" though?

[@eamh2002]

@@AntonMakesStuff He means that the propeller is made to "slip" and not grab the water too much at low speed by having it in "bubbly" water so it can speed up and have the engine get up to speed faster. If the propeller doesnt "unload" aka "slip" it will bog an engine down and the takeoff will be very sluggish :)

[@carlwest859]

The formulae is to take an existing design or product and modify the design through reverse engineering, simplification and inexperience while utilizing modern technology, video editing and humor. Most entertaining channel and he has me hooked.

[@fastSPX_90]

hi, I don't think the propeller you printed is actually toroidal. It looks more like it's a regular propeller but with a hole in the blade if that makes sense. The point of toroidal propellers is that the extrados of the blade on the lower half becomes the intrados on the upper half, and vice-versa. So the blade sort of curls back to the propeller shaft. Look closer at the blade "tip" of toroidal propellers if my explanation isn't clear, they're not the same as the one you printed.

[@magnusandersen8898]

[@Joffes]

Without sponsorship, PCBWay is quite expensive, therefore I would recommend trying "Lost PLA casting" or maybe just metal casting overall. It is a bit of an extra step, but in many applications i think it really would benefit you when normal 3d printed material just doesnt hold up.

[@kitsandham7001]

It’s been a while since I’ve cast stuff, mostly precious metals (or brass for the fun stuff) Good hand made wax moulds took me ages. You just blew my mind with ‘lost PLA casting’

[@rican9494]

Love watching your videos and I've been talking about my brother about converting an outboard motor into electric for my boat almost 2years ago😂. Thank you for the video, and now you made me want to start my electric boat project😂.

[@Snookers_]

I don't know if you've already finalized this yet or not, but mirroring the mounting/hinge setup so that it goes on the top and bottom of the wood beam would _massively_ improve its strength. If you did this, I'd be willing to bet you could even keep the mount made from plastic without any issues. I did some very rough math and estimated an increase in strength of an order of magnitude or two. The biggest drawback to this is you'd need to find a way to get the whole setup further underwater since it would raise it even further in its current mounting configuration. Also, as others have mentioned, using the original mount would also solve this issue.

[@adamreynolds3863]

Heating up the PLA and forming it after assembly was a really smart idea!

[@kruzidru1374]

That photo in CAD trick is life changing. Noice!

[@traviswilliams3209]

[@TheRoemer1]

Love it! And the approach... I always asked myself why everybody is diy building electic motors under water instead of this and now finally somebody did... think about maintenancing your drivetrain and there usually is also a water inlet with a tiny plastic wheel that gives the engine water cooling... maybe hook that up to the esc.

[@AeroGraphica]

Use this motor with a direct shaft like the longtail racers in Thailand ! There are too many things wrong with this build, it is never too late to ditch it and start on a clean base, so you can spend more time having fun. And you can build a small longtail speedboat out of aluminium sheet or fiberglass. All you will need a high pitch prop.

[@AndreasBested]

For testing motors we've used a trash can where we could mount the original bracket on the edge and fill the bucket with water. That might help for quicker testing at home 😊

haha I like the new screw driver animated effects. I would've used those bolts from the top, put nuts all the way to the top and tighten it, now you have 2 threads that are super stiff and straight. then placing it down you can mark the holes and place 2 nuts on the bottom and top side of the tray. then cross threads on the front and/or back to the 4 corners to stop it twisting. your propeller I would've coated it with resin glue or UV one and then just put it outside hehe use bearings on the turning parts rather than roughing it out.

The cavitation isnt from waterline, its because the exhaust is routed through the impeller housing from the motor housing. You will need to block that off.

[@gth042]

Ooh, good point!

[@juhanaleiwo]

It would exit behind the propeller so I suppose it wouldn't hinder the flow in the propeller blades much. I mean, there's exhaust gas coming out in normal operation too.

[@colinsmith6340]

@@juhanaleiwo it would depend on the impeller design i would imagine.
