I have one
It's a Navigator (they were sold at Cabelas)
Same company makes the Panther lifts for trolling motors

Mines a 55 thurst pounds 24v on a 18' Amumacraft
Use it all the time trolling. I get about 8 hours out of it
It's great. No noise and can dial in any speed that I what
keeps the hours off the big motor and with gas at 4 bucks it helps

If I had to do it over
I'd go with the 80 thurst pound model
In extreme wind it will not push the boat into the wind
My front trolling motor has no problem (80)
But for most of my trolling I'm a little under half on the speed knob
