Hoping a few of you Champion guys can give me a little info. I currently have a Minn Kota 101 Maxxum (older model) installed and want to upgrade to a Ultrex. My setup is a 36volts and factory 40amp panel mounted circuit breakers in the battery compartment. I know I will need to upgrade to 60 amp breakers for the Ultrex, but have I been undergunned on the circuit breakers by having the 40 amps all this time? I haven't had an issue yet. Were the older Maxxums set up for 40 amps? I see on Minn Kota's website that they say 50 amps on the maxxums. Thanks for any input!
