Minn Kota Endura C2 vs Endura Maxx

[TriStateBassin106]

Title says it all I have a bass hunter 120 coming in and I need to know which trolling motor will be better to push me around (280lbs) also what upgraded props make it go faster/weedless.

They are the same except the max doesn’t click between speeds. I have the endura max and like it. If you’re wanting to make it more weedless get yourself a ninja grass blade and put it on the trolling motor. If you want to go fast jump to a 24 volt 80 lb thrust motor.

The Endura Max has a PWM circuit, if I understand that correctly.  So it controls the speed by pulsing the voltage to the battery.  At slower speeds, it rapidly switches between full on and full off.  It does this at a high enough speed (frequency) so that the motor still runs smoothly and doesn't stutter.  What that means is it will be more efficient, battery wise, on lower speed settings.  The C2 doesn't.  It uses a series of resistors to lower the voltage to the motor.  This means it supplies the full voltage of the battery any time it's running, but due to the bleed off from the resistors, only part of it reaches the motor.  The rest is expelled at heat (though probably not enough to notice).

 

So at full speed, they should eat up the battery about the same.  But at half speed, the C2 will eat the battery about the same as it does at full speed, but the Max should only eat the battery about half as fast.  So, if you're using the trolling motor at around half speed most of the time, you'll get a lot more life with the Max.  If you're using the trolling motor at full speed most of the time, there shouldn't be a noticeable difference.

 

Also, the PWM circuit does create more electrical noise.  So it could interfere with your transducer on your fish finder more easily than the regular C2 would.  However, if you set the system up properly, and have the trolling motor grounded efficiently, it shouldn't be a problem.  You just have to be a little bit more careful with the wiring, that's all.

Thanks for this explanation.
