For what it's worth I started out with a Motor Guide HAWG on my aluminum bass boat in 1978 and didn't have to replace it until around 2003. I replace it with a Minn Kota All Terrain 50.
Both were good trolling motors for their time. The newer trolling motor has more power and I had to add a 50 amp circuit breaker to my boat. I wish that the wires were bigger too. I need some 6 gage wires for the 16 ft run of wires from the back of the boat to the front of the boat. Larger wires carry more current with less voltage drop.
