Aeromarine 44" hydro

Very well made boat and very fast!

Probably some material defect in the wire(s), if this is fan cooled too then cooling was not the cause. Hopefully Neu will take care of the motor.

Prop was the same, Octura X455, balanced.
Water cooling was working. Something must have happened inside the stator that caused motor efficiency to go down, thus more heat and slightly less torque output. Good thing that magnets don't feel demagnetized. If motor can't be fixed for free, getting new stator is not as bad as buying new motor.

You may have picked up a bit of debris around the rudder when you launched or soon after and this may have put a bit of strain on the motor causing it to heat up and knocking a bit of your top speed of at the same time, especially when your batteries started to run down. The debris would have fallen of your rudder when the boat stopped and you would not had seen that when you picked the boat up.

Worse case scenario......I am pretty sure Neu will give u a new replacement for 50% off

I kinda doubt that because boat felt slower as soon as i got it in the water. Water was rough, so boat did a lot of jumping. On passes close to shore, it did not look like it was dragging anything. I quickly noticed slightly lower pitch of prop sound which means lower rpm. It was not a huge difference, so it did not alarm me much. Oh well, i guess it's important to have temp. sensor on the motor and program the controller to shut down if unusual temp. happens.

Edit: Screw this guessing. I am running my data logger at all times from now on - 3 temp. sensors, GPS, RPM, volts, amps.
