Re: [Electric Boats] The plan

 

Define how slow is slow.  Anytime you are thinking about a trolling motor understand that no matter how big you will still be going trolling speed. You will likely have enough thrust and I understand you don' t want or need power boat speeds but understand that you do not get anywhere fast at trolling speed.

DOUG, I would recommend caution in using the system you described. In addition, lithium batteries are lighter, but they only need to be installed once, so weight should not be an issue as they should be recharged right on the boat. Lead acid, gel, flooded cell are heavy but much cheaper. I would recommend two 12v batteries and a 24v 80 lb thrust motor for your boat and as others have advised, windage will be an issue with your houseboat. Good luck and keep us posted.

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
