At WOT on my 180 (yamaha f150), I hit 5100 rpm with 39 mpg today.
I think thats pretty good.
What is your performance data like?
(Approximate extra weight 350 lbs which includes my weight and two batteries plus a bow mounted trolling motor.
In the gallery, there are photos of a GW180 with a bow mounted Minn Kota. I am considering to do the same. (Minn Kota Riptide ST 80/CP/AP 60" 24V) What are your thoughts on this setup.
