Hey everyone,
I need to know if there is a motor out there that falls into all of the following:
- Is waterproof
- can be hooked up to batteries that are waterproof
- can make about 70-100hp (doesnt need to be very fast, just a decent amount of torque)
- can be setup to use a throttle cable (or something that will be able to react like a throttle cable (having the ability to hold the throttle/power on at different rpms but able to switch like a gas pedal in a car)
- a motor that ismt ridiculously heavy
- be able to move 200lb hull and atleast 150lb person on said hull

Now I know thats alot to ask of a EV setup but I just want to see if its possible as for the project Ill either be using an Ev setup or a 2 stroke engine setup, so let me know if its possible.
Thanks

With these requirements, sure it's possible. Again, a trolling motor and a big battery will easily move that weight around for a pretty long time.
 
The weight of the twostroke engine setup is no more than 100lbs

Not from what I'm seeing.

50HP Yamaha 2 stroke outboard - 75kg = 165lbs

Yamaha 70hp 2 stroke outboard 105.5kg = 233lbs

The 70HP motor weighs more than the boat, and is typical for a boat 10 times the weight of yours.

"The rule of thumb is based on weight alone, and says you should have between 40 and 25 pounds of weight for each horsepower."
