Rideable Electric Speed Boat Build - PART 1 

Subbed!

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

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

​@@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:)

And you never now when and if there will be a next video

@@slothandturtle8036 someday we will find out via carrier pigeon that due to a tragic electric surfboard accident that rclifeon can no longer use his arms and therefore can no longer upload 😔

@@eightfold3195 Until he builds 80V water-cooled electric arms.

❤❤

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.

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

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

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

❤❤❤

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...

❤❤

@@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.

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.

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

@@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 :)

@@eamh2002 That is very interesting, thank you for sharing!

same here

Right? Or made even a small CNC mill

@@Fosterforged solid idea there Sean, why not both!!
