I have a question! why do people use old golf cart motors on these builds. when you could use a ac motor with a vfd. to control the speed. this has advantages to many to list. but at least the weight of the wires alone. and batts to run it. rpm from one to three time the tag rpm are possible. and 100 percent of torqe. @ one rpm. inverter to 120v to vfd=3 ph out. freq drives and motors are cheap used.
@advthinker the main issues with using a VFD and AC motor is that the voltage is much higher - which is not ideal for safety in a boat, and the VFDs are not normall designed for use in damp and / or salty environments.
Ideally I'd use a permanent magnet AC (Brushless) motor running at 24 or 48v.
This one was really just a test for the motor and controller, which is now in a motorcycle.

Wie viel Watt hat der Motor und welche Geschwindichkeit erreichst du damit ??
How many Watt has the baot and how fast is it ??

@Damir819 on that test run I measured a max of about 4kw into the motor.
It did about 10km/h (similar performance to an 8hp 2 stroke engine with two or more people in the boat)

Does it do anything other then slow down and stop...

@tcrote5516 funnily enough, before it could slow down and stop it had to start and speed up!

Nice boat. What kind is it?

It's an old Carribean 11 foot runabout.
I'd say it's from the 60's, made in Australia

wtf is that ugly thing
you need to get yourself a internal combustion engine
