Re: [Electric Boats] The plan

 

No, you can not use higher voltage on a 12v motor, it will overheat. 
Trolling motor might work for very short trips, but I would go with a torqueedo 2.0, if money is not an issue. 
Trolling motors are inefficient, and probably not powerful enough.
If you like tinkering, you can modify an outboard to electric.
You need at least 2000 watt motor, and I would try and get around 3000 watts or higher, so you have extra power for when wind and current are against you.

Good morning folks.

I have an 18' trailerable Hobo houseboat that needs a new power train.

For many reasons, I think electric is the best way to go...the biggest reason no doubt influenced in large part due to my own personal strength limitations after suffering a stroke in the last couple of years.

Trolling motors are not very heavy and Lithium batteries weigh much less than your standard lead acid ones.

The plan is to locate a used 12v trolling motor with the "best thrust for the buck"
and power it with a Lithium battery pack used for e bikes and mobility devices.
These battery packs are often available in voltages more than 12v (36, 48 etc.)

Can a 12v motor be hooked up directly to a higher voltage battery without modifications? Benefits of better efficiency at using higher voltage regarding speed and range?

So is this doable and what should I expect to see happen? Tips?

My boat weighs under 2,000lbs and I have lost the need for speed I had in my youth.

Regards,
Doug
