Ok forgive me if this was covered in past posts but I did go through and look over some of the 497 that came up. But none of these actually fit my qusetion. So I have just aquired an older Brute 67 that came off a '99 Triton. It was missing the switch that controls the variable speed and I got one from a motorguide shop here. Now my question is I hooked it up 12v for 2 trips maybe 3 hrs use then I put another battery on it and it doesn't seem to make a difference in the thrust. My neighbors 70# WAY out preforms mine. Is it my motor or what? Thanks
