Re: [electricboats] Somebody help Capt. John

From a heat perspective, the props could be oversized, but never undersized.  

The smaller the props the less load on the motor, and if the motor is shaft fan cooled the faster the shaft fan would spin.  

Your choice to fix that would be either a smaller prop, or more gear reduction. Both choices would introduce some efficiency loses.   

The amount of heat your motor can handle for continuous use, is dependent on the motors windings insulation heat rating and is therefore completely unique to your particular motor, generally the motor manufacturers should supply that information on request.

Thanks for the reply, cables from batteries are 00 pacer and look proper for application to the breaker, shunt, solenoid, from there to the wire looks like 10ga pacer with spades that fit the lugs, the same to the motors which are comparative in size to the motor leads. I'm starting to think the motors, or props are undersized or something like that. I see your point, at some point going from 00 cable to10ga is a bottleneck however I have monitored the 10ga wire temps and they don't seem to heat up as much as the motors, but are the motors to hot at 146F? Each are on separate systems and both produce very equal numbers.

Hummmmm?
