It's Only A Matter Of Time

[Old406Kid]

Before our "Electric Motors Only" regulation gets rewritten.
I saw this on a BC site and along with many others that commented have no idea what size of motor this refers to.

I guess it's time to do some calculating.

Basically it’s 10 horsepower (746 watts = 1 hp) which seems huge for an electric trolling motor.

Converting to an equivalent lbs thrust is a more complex calculation.

With the advent of electric outboards I figured that it equated to <10hp but it would be nice if they added an either/or while in its infancy.

To get an equivalent lb thrust number we need to know the top speed of the boat. So then we have force x distance (=energy) divided by time (=power).

I found a calculator on the web and put in a few numbers to see what it looked like.

A 30# motor moving a boat at 5mph was .4 hp. Which seems in the ballpark of what I’d expect.

(I’m not sure what top speed I could get with my 30# motor on my pram, would be fun to try to check it with a gps sometime)

Then I tried 120# thrust moving a boat 20 mph and it said that was 6.4 hp.

What’s the biggest electric trolling motor (lbs thrust) out there?

I saw a 3hp electric trolling motor, 36v battery.
Setup was around 1800 bucks for motor and battery the guy said.

I saw a guy at coldwtr lake with a motor called a torquedo. I don't know what the horsepower was but it moved his little boat like a gas motor dinghy. This was a decade ago and I can only imagine the technology is better. He was pretty much on plane. His battery bank was extensive.

Here’s a local company making electric outboards…
