Hi, locking for a low kv 65XXX motor for direct drive kayak motor. Dosent need 3000 RPM and 20 knots. So a slower and larger propeller for 5 knots will be more efficiant.
Can only find 65XXX motors in 100KV+ range.
Regards

The 100kv motor is actually closer to a 95kv motor. Just use a lower voltage and you’ll have a lower speed.

Yes, but my battery is 12S/48V. So the amp draw on 12/24V is to high.

It will work, but hassle to get a gear to work. Have contacted maytech and they can deliver custom KV. But the “situation” in the world, it will take 30-45 days.

I would say just make an order, I struggle with this all the time, I procrastinate and overthink stuff and so 2 months go by and then I regret not ordering what I needed, cause it could have been arrived already.
Time flies, if you know that it’s something you NEED, just order.

Will not be much load on the motor, you probably need less than 1000w to achieve that speed on a kayak!

Both 100 and 120kv are the most popular, you can just use a simple RC 6s Li-Po, (instead of 12s hydrofoil traditional system) you would also be able to use the same motor on a e-foil in the future, don’t be too hard on yourself, I would take the 120kv.

I have built a large 48V 4kWH battery and have a small trolling motor, only 500W the kayak goes about 6 knots. But want to try 1000W+ and maybe 8-10 knots.
