The boat looks fantastic, I wonder if there’s interactions with water turbulence or if the pitch is too high for the current speed of the boat causing a little bit of vibrations. Maybe try adding those small outboard hydrofoil/anti cavitation plates?

Then you'd expect vibrations when accelerating hard... doesnt make sense.

Nice project. Maybe if you are worried about vibrations damaging servo, you could think of some tpu damper between servo horn and linkages, so it isnt stiffly coupled. Looks like it wouldnt affect precision of steering in any measurable way, but could dampen those vibrations.

Your videos have totally inspired me to do the same thing. I bought a big ass LiFePO battery and a trolling motor and built a frame to mount it on my inflatable canoe. Spent the summer cruising the waterways in my country every few weekends. My build was much less DIY, I just shilled out the money for ready made parts, since I don't need autopilot or stuff like that. Cruising around the waterways is the most calming, satisfying thing ever, highly recommend. Thanks for putting out these videos, they're always a joy to watch!

[@NickWainwrightcreates]

The rubber in the prop is a safety point that can flex if you have a prop strike. Pretty standard on boat props.

[@Shoefly007]

So glad to see you went this direction. The magic of KZbin for me is watching someone else work through very similar ideas to what I am working on. I can attest to the resilience of PETG (mine connects the motors to the boat’s helm). It is not underwater, but has been in all the elements over the past three seasons.

[@SailingFrolic]

Dude, I’m so impressed with the quality of work and engineering you used to build your boat. It’s unparalleled on KZbin thus far. I will say, you might want to consider simplifying the mechanisms and linkages to make it easily repairable on the go. I’d also recommend a PWM between your battery and motors as it will reduce the amp draw on your battery over time, since motors generally use higher amps than they convert to power at lower speeds, and the remainder of the energy is converted into thermal energy. A PWM will mitigate that issue considerably, increasing effective range by about 20%. The other thing I’d recommend is having a couple small Amazon kayak sails for $20 (the kind that looks like a circle). They only work downwind, but in the event of a motor failure, you’ll have a way to get back to the boat ramp without breaking too much of a sweat. You could also install some dual purpose oar-locks for rowing the boat, or use them to hold fishing poles or GoPro mounts. You did great in designing redundancy into the systems! Definitely get a waterproof laptop for the next voyages! I was terrified for your Dell watching this video. Especially if you have any important data and calibration software for the boat that might make it unusable without it. You have to name it! Name idea: Arr Sea 🌊

I really hope you give those motors a chance at recommended voltage and 2X the recommended amperage available. I know...expensive controllers and batteries! I actually love the batteries you have, you just need more of them. Once you have all that power you truly appreciate the motors you have.

Hey there! I see you have two of the same props on there. Turning the same way. This might increase the propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk). You won’t notice this much when going forward. But when going backwards this might become an issue. If you have 2 props. You need them both turning different ways to counter this effect. I love the project so far! :) it’s amazing what you do. Keep it up!

For props try using 8" (or so) RC Airplane "APC" brand pusher propellers. They work extremely well and are much more efficient than a typical boat prop at these speeds due to their long aspect ratio.

[@planespeaking]

You need the rubber grommets on the servo, not the props. This is awesome. Next, a full on EV speedboat.

[@Luggeluggewisdd]

in aviation, there is a thing called prop sync, used in reciprocating and also turboprop planes; syncs one engine to the exact rpm of the other. if youre interested i could get some more information, im working at an airport where the one of the biggest producers of props and those sync electronics are based. would also be interesting if it only vibrates if both motors run on full thrust or at all time. For the servo i also had an idea; you could use a big rubber grommet or rubber bearing on the driven shafts. would decimate your wear and tear on the 3d printed parts i think. best wishes

[@KnowledgePerformance7]

I don't have a ton of powerboat experience but I would attribute the vibration you observed to cavitation. Cavitation is inherently chaotic and will cause differential thrusts and vibration. It's hard to see if that is actually the issue, but I know it's an issue on every RIB I have driven

Nice job! This is what it’s all about, taking a project boat, your imagination, tools and skill set, and challenging yourself to make something that can be used and enjoyed for exploring.

Looking forward to solar integration and bigger motor controllers to see what those E-foil motors can do pushing that hull.

[@dav1dsm1th]

Great video, as always. Maybe try a little K.I.S.S. Rigidly mount the motors to the boat (and use differential steering if required). Add a tradition rudder/tiller (with a linear actuator for automated control) for manual/backup steering. You could make a linear actuator using 3D printing, threaded rod and a nut - or CNC it all in aluminium for strength/precision. Stay safe out there.

[@Highstranger951]

The rubber part in the props is the hub. It’s made to absorb pressure, light impacts and dampens harmonics. The gap between the prop and motor is what is causing your vibrations.

[@realhusky]

Just a tip the best way to epoxy something like that is to use a spreader, wet through the back of your cloth then use the spreader to apply it to a wetted surface. Another tip, you can use nail polish on your electronics for protection then pot then in epoxy with the wires connected. That rubber piece is designed to shear after it gets a high speed jam, like a line around the propeller. It breaks instead of the crankshaft

[@johnpickens448]

Since you have 2 motors you could do azipod steering that big ships use. You can go sideways, turn inside your length, etc.

[@francescotravi6615]

The rubber between the shaft housing and the propeller it's used like a damper to preserve the motor. It absorbs the torsional force during fast acceleration and reduce vibration caused by cavitation. It's not made for self balancing. Probably the wobbliness that you experienced came from the two rudders becose of cavitation effects an karman trails. Try to make a slicker design and you will see that the water can stay attached more to che surface reducing vibration. Grate video!

[@Zothaqqua]

For your steering servo and vibration -- you probably don't need your system so rigid. You could use a more flexible horn, or a pulley arrangement with rope. On my boat, I have rope-driven wind vane self steering that has taken me across seas, and the connection is quite compliant. The key there is that there is negative feedback from the wind direction to compensate for any flex.

[@AntiVaganza]

The rubber bushing is not a self centering feature - it's to protect your lower unit gear/engine from breaking when you hit a rock. Idea being that the prop starts freewheeling on the bushing. Before the rubber bushing, you would have shear pins.

[@RoaldvanDijkenHOT]

This might be a bit late to the party, but a typical vibratory exciter on ships is the blade passing frequency. When one of the blades moves past the outboard body it loses some off its thrust. In your case the frequency is prolblably 3x the motor rpm because 3 blades. Be aware having 2 props spinning not in sync gives this output twice. The solution would be optimising the hydrodynamics to dampen the flow disturbance somewhat or increase blade count to smooth pressure spikes.

[@stephensmith6055]

This is amazing! You could static balance the prop just like an airplane prop. Would make a cool 1 minute segment. Also skim coat all the wood with resin, it’ll keep in in great shape for a longgggg time. Or soak in wood sealer for a few days. Always looking forward to your videos!!

[@aggonzalezdc]

Welcome to boating on hard mode. My grandfather was building rc sailboats back in the 60s, using tiny canvas sails and strings wrapped around servos. I, notably, have not taken up the same challenge lol.

[@jeroenimo99]

First, nice work!! Enjoyed your video a lot. Just a few thoughts from an old sea captain: 1 The rubber rings in the props are not for centering or balancing. They can slip if you accidently hit like a log, rock or something else and protect the motors. 2 I think your props are for high(er) speed (bigger pitch) , and your boat is a displacement boat and you will never hit the designed high speeds for the props. This would explain overheating of your motors. You need props would need less pitch...

[@jeroenimo99]

Plus for steering, and 100% perfect maneuvering you would need independent rudders on both engines, I'm not sure if that would be easy to program into a autopilot.

[@thecatofnineswords]

The rubber things inside the propellers are there to protect the motors against the prop blades hitting things underwater. It happens far too regularly! Much nicer than shear pins.

[@goldendredger]

The rubber inside the hub of the prop is in case you hit a rock or solid object. To both absorb some shock and will rotate as well to keep from ripping drive shaft in two. The inner brass cog will spin on the rubber inside the prop. This setup is a bit better than a solid prop with a shear pin. After a prop strike this rubber setup will work even though it spun. Where as a shear pin on a solid prop is done until you put a new shear pin in.

[@The.Norwegian]

for the interested: the rubber in the prop hubs' main job is to reduce wear in the gearbox on regular outboards. when you shift, you are smashing two flat pieces of steel together in the gearbox (driveshaft and propshaft get connected through the clutch dog), where the driveshaft is at 7-800rpm (or more), and the propshaft is standing still. getting the propeller up to that speed in an instant is not so great for the clutch dog, so the prop hub is isolated from the prop with rubber to dampen the blow. it also takes out some vibrations at low rpm, and help a little bit if you hit something, though they are not meant as shear pins. your prop will still break off all the blades and bend your propshaft if you hit something big. you don't really need those rubber inserts here, as the power delivery from an electric motor is smooth, unlike in gas powered outboards, and you don't have a shifting gearcase.

[@keegan707]

The rubber is meant to shear if you strike or wrap the prop.

[@joshuaserum1661]

I worked at a marina in michigan for 4 years the rubber piece in the prop is a shear hub it a protective device for the prop incase it hit something hard the plastic sleave will shear on the inside and keep the porp from chipping/breakinging. Awesome job tho I think your projects are awesome.

For the steering, maybe look at how electronic servo steering works in cars, in my car it is just a ball screw which is attached to the steering arms and nut for that is rotating around to push it from side to side.

[@birdvalenchez]

As a Marine technician, use marine grade parts!!! TAKE parts from outboard motors old yamaha or mercury parts and use cable based steering brackets or universal marine grade parts on your boat. The reason the servo stripped and your prop was experiencing so much vibration is because propellers on outboards are equipped to beefed up lower unit (basically transmission) systems that are completely submerged in gear lube and locked down gears and bearings are pressed together at hundreds of pounds of force. If you cannot have some sort of lower unit incorporated into your electric motor it simply won't handle the load you're putting on a prop

[@friendlyfire01]

rubber in between drive and propulsion, like inside a propeller or inside the rear wheel of a motorcycle, is usually called a kush drive. it allows smoother operation! On my motorcycles it keeps the motor from 'thumping' the rear wheel.

[@allansnelder3292]

and also if you strike the bottom the rubber will rip and hopefully save your shaft
