      You would be better off using something less complex that doesn’t require extra energy “other than the engine” like a centrifugal go cart clutch. No engagement lever or mechanisms. It’s in freewheel mode at low engine RPM and slowly gets to near full lockup at design RPM.
      It’s neat to design/ build your own parts but it’s a lot easier if you’re not “reinventing the wheel” on every one of those parts. Some designs like the go cart clutch are so simple and dependable that there’s no need to “rework” them.

    The water pumps on those tiny engines are typically well undersized for the cooling needs of the engine. I think a reasonably powerful little electric pump would be the way to go to make sure the engine isn't getting too hot. Also if you swapped the starter motor for a DC motor you could use it as a little generator and maybe keep the batteries charged.

    The universal joint is not ideal because it is not a constant velocity joint. It "pulses" as it turns if it is not straight. A way around this would be to use two joints out of phase, but they need to be arranged so that both bend at the same angle. For a clutch, I wonder, can the electric clutch from a car's AC pump be operated progressively? Otherwise a simple system would be to use a belt drive as an adapter and just control the belt tension to work as a clutch.

    A few Ideas I thought worth sharing.
    On the outboard unit, have the stearing pivot axis oveverlap with the axis of the vertical drive shaft this way no mater which way you turn, the vertical drive shaft will remain in the same position relative to the paddle board, base, etc. This will eliminate the need for a U-joint of any kind.
    Instead of running coolant, have the engine take in cool water from the lake and dump it back out; no recirculation. This is the standerd in the boat industry. You may also want to use a small sea strainer if you go this approach.
    For the noise, you can always extend the exhaust to go into the water.
    I really hope you figure out the carburetor issue.
    Anyway, that things super cool!
    I hope to see it refined and back out in the water

    @fluiditynz Рік тому +21

    You need to move your weight a bit further back to plane. I don't think you have enough power though. Less wetted area and displacement, less drag. As you are nowhere near full motor output, go lower pitch and diameter on the prop. Lower pitch will give you more push but less diameter will unload the engine more and possibly permit sufficient combination of torque+RPM to get your SUP board to plane. That's your next goal. From there, you can optimise pitch and blades, diameter to get best planing speed. Beware water ingress into cylinders. Trying to compress water doesn't end well. For that reason, don't put hydrofoils on at this stage. Lots of refinements needed yet.

      Yes, scientific approach totally missing here, just accounting on the mythical name "V8" to solve everything. You should put your motor on a power bench to find out at which RPM you get the most power,then determine the speed that you can expect with this power, and enter those number into a propeller calculator that will give you the pitch and diameter you need.

  • @EstorilEm
    @EstorilEm 2 місяці тому

    In the powerboat game this issue is the first thing you learn about, you have to find an appropriate diameter prop first but the pitch is the big issue. Too steep a pitch and the motor will load up, same thing as pulling from a stop in 2nd gear with a car - the big prop was probably ok (maybe a little smaller would have been ideal) but you want to change the pitch so you reach peak power (would help if you had a dyno curve for the engine so you know exactly what that RPM is) right about at the limit of how fast the engine can turn the prop at WOT.
    For conventional engines this would be like putting a crazy prop on an engine that makes peak power at 5500rpm but the prop only lets it get to 3500. Could be the difference between ~320hp and 180hp actually being delivered to the water.
    Again, blade pitch is like differential gearing in a car - I know you get this stuff but it’s definitely “a thing” in the powerboat world just like with cars.

    I wonder if you could increase efficiency if you changed the U-Joints in single arrangements to duos. The engine wobble may possibly be due to the single u-joint arrangements causing nonconstant velocity output as well. If you added a second UJoint it wpuld counter the other and gives you a nice constant velocity output. and erase the slight horizontal movement that comes with a single joint system.

    Like some others have mentioned, doing a setup like the Thai longtail boats would probably be the most efficient, although you may need a 3:1 reduction out of the engine to get any kind of appreciable torque. You should maybe set up a small electric pump to pull water directly from the lake for your cooling setup, either with a heat exchanger or good filters on a direct setup to keep trash out of the cooling system. On those Enjomor V8's, you need to set them up a little rich on the idle circuit in order to get them to rev out under load.. also, they should have a bit of pressure on the fuel tank, since the diaphragm pumps in the carbs don't work well at W.O.T. (no vacuum pulse). On gasoline, you may need an external pump to keep them supplied, while being careful not to overpressurize the carbs. Hope this helps..😉
