Re: [Electric Boats] Re: 36 volt Motor replacement for Duffy Sport 14?

 

The five minute wait may be automatic thermal cutout, a safety feature to avoid cooking the motor.   Immediately after shutdown a motor often gets hotter than when running because the cooling fan is off and it is often in an enclosed space.  If you cannot hold your hand on the motor for over a whole minute then it is too hot.  If you spit on it and get a sizzle , it is too hot.   You could try a bilge blower in the compartment or an open hatch for extended running as an experiment  to see if it still happens.
Just my 2 cents worth.

I think its more likely in the solenoids or controller. However, if you need to rewind the motor, I have rewound two 2hp, 24v motors and its a bargain compared to replacing it. Just google motor rewind in your area for a price.

I have a problem with the motor running fine across the lake, but when I stop by putting in neutral or reverse after a extended run, it will not run until it sits for about 5 minutes. Then it runs fine again. Duffy said it sounded like at least one of the solenoids may be gone. I have 5 new solenoids on order but wonder what my next step will be if this is not the problem. Motor? The motor in the boat now is a Leeson Model C4D170C1A. Cat #108813.00. 36 volt. I have so far been unable to find it on the internet. Anyone have any ideas. Anyone have experience in having DC motors rebuilt or is it not worth the effort?
