Thanks for all of that info! awesome idea about the ebike conversion kits genius! Next video please give us some battery draw, gps speed, speed at different draws, how long will the battery last at that draw etc. Thats crack for us people who watch these kinds of video's :)
Thanks for your questions. It was a fun build. I've actually handed off the motor to a friend of mine but the rough numbers when I was using it was around a 40 amp draw at top speed; on the heavy fiberglass, deep V boat I was testing it on top speed was around 5 to 6 mph. Battery range and run time would be dependent on speed. A small reduction in speed would greatly expand range of course. On a light aluminum boat it would probably do very well.
Those motors produce a lot of torque at the low to mid range of the rpm, a bigger prop helps to use that 2000 watts for efficiently. Gas outboards have high rpm output with the torque coming in at the higher rpm. BLDC or just DC motors can turn a big prop easily. Big prop, deeper angle. Paddle that water out of the way.
Very interesting, cheers for the video! May I ask, is the motor at the top and using a shaft to the original propeller or do you have the motor at the bottom directly attached to the prop? If at the top are you therefore pushing the power through the original gearbox too? I guess the motors that Epropulsion use must be quite small to fit down below? Either way it worked really well!
Thanks for your comments. It does look Stormtrooper like. This outboard was pretty typical of most and had a 2:1 reduction ratio. So the top rpm would be cut in half, but in reality the motor can't really be run full on for long periods of time without more cooling. This motor was on a somewhat heavy, deep V, fiberglass boat and was pushing around 1,000 pounds. The 2,000 watt ebike motor is between 3 and 4 hp at best so top speed was around 5mph. On a lighter, flat bottom boat it would do far better.
Thanks for this! Great video and very much what I have been looking for. I wonder what your thoughts are about this: sound/noise level - It seems like the immersed motors (Spirit 1.0) are much quieter than the Ebike-headed motor (which would make some sense.)
Looks great and great weather for splashing!
You need a huuuge electric motor for that thing to get her on plane! Nice job…
Thanks. Anything is possible. We will see!

This is a cool project!
Thanks! It was a lot of fun to build.
Love your channel Wayne!

Cool beans man , I was thinking about doing a conversation like this. 😊 Pulley stearing , that brings back some memories
Thanks for your comments! Fun project. And, yep, old school steering still works.
That's great, appreciate if you show us how you connected the motor to the shaft and parts used.
Very cool! Could you link or mention the motor you bought on amazon? Thanks!
Thanks. These kits are all over Amazon and eBay or directly from Vevor.
I'm planning on building a little flat bottom jon boat since Liberty reservoir in Maryland is electric only. Any tips would be greatly appreciated.
I am also in maryland, I would love to check it out if you are semi close to carroll county
Very nice... Thank you for sharing
Fun project!
Can this be done with bigger motors like a 150hp?

Thanks. It was a fun project. The motor is mounted at the top and drives the original gearbox.
Love the design, very Stormtrooper-looking. What kind of speeds did you get compared to the 5 hp? Did the gears affect the speed?

Top mounted electric motors are definitely louder. Motors mounted in the hub under the water are a joy to use.
Fantastic man!
Thanks. Fun build!
It works 😅 don't It proof of concept
Plywood mounts are a joke.
