Looking at putting on a transom trolling motor on my 17 foot tiller. What speeds can I expect with an 80 pound 24 Volt system? I think I can only get 1.8 – 2.0 with my 55 pound bow TM.
Finally any one have the traxxis? What are you thoughts? Not sure if I can swing a Vantage.
Thanks
Aaron
Well, to look at it simply you could say:
F = b*v^2
where: F is the thrust of your current trolling motor (55lbsf) and v is the velocity you obtain with the trolling motor. b is the viscous coeficient of friction of your boat.
So:
55 = b * (2.0)^2
Solve for b:
b = 55/4 or ~13.75
So with the new trolling motor you have:
80 = 13.75 * v^2
Solve for v:
v^2 = 80/13.75
v = (80/13.75)^0.5
v ~= 2.4 MPH

That is what I was going to say as well but he beat me to it. 
Thanks! Learned something new today. Im heading home.

If you can’t swing it for a vantage yet then wait until you can! Worth the wait!

I was afraid of that answer. The wife is going to kill me.
Keep looking on Craigslist for a deal on a used Vantage, and do not be afraid to make an offer, I found one up in Park Rapids that was 2 years old for $650.00. Works like a charm.
