Electric Motor & Boat Question
I have acquired a Chris Craft model with an electric motor installed but no other electronics. The motor is a “Peak Racing Motor” and has Nightmare 2 on it as well as Roar 98 and Epic.
I would like to know what I need to add to complete the boat so it can be run. I know I need a surface TX , RX, and servo for the rudder but I don’t know what I need to run the motor. What ESC would work and what battery size/requirement.
Thanks, Jim

RE: Electric Motor & Boat Question
Hi Jim,
Welcome on this forum!
Would you be so kind as to give us some more information on your boat, such as length, beam, weight?
Also the size of the motor ( Ø and length).
Also a few pictures are greatly appreciated!
The more info you provide, the more specific suggestions we can offer.
Regards, Jan.

The motor is 1 7/16" in diameter and 2.25" long including hubs. The shaft is .125" in diameter.
Here are some pictures.

RE: Electric Motor & Boat Question
Wow, that's a lot of boat weight (and size) for such a small motor...
What size prop is it supposed to turn? (picture please)
I'd be careful not to overvolt this car motor, in my opinion it is way too small for the boat.
You could run it on a 7,2 V NiMH pack and a 35-50A ESC and see if the motor holds up.
The pic is a bit fuzzy, so I can't tell if there is room for watercooling, but I wouls at least add brushtab cooling on it, by soldering a piece of brass tubing on the brush holders and run water through them.
Beautiful boat though.

RE: Electric Motor & Boat Question
I've been searching for running gear for your boat and came across this thread:
http://www.rcgroups.com/forums/showthread.php?t=785514
It seems I'm right about the motor being a tad on the small side, be careful not to burn up your motor and the boat with it...

Thanks Jan,
The information you provided is very helpful. I know the motor might be small for this vessel but I think we intend it to be more of a cruiser not a speedboat or race boat.

Oke, as long as you're aware of the potential for disaster with an non cooled small motor.
Keep us posted please.

James,
That is a very nice boat!
I agree with Pompebled. At some point, it may be a good idea to get a bigger motor for your Chris Craft. A bigger motor doesn’t necessarily have to be a faster or an expensive one, but it should at least have the capacity to run your boat reliably. Once you have the boat ballasted with batteries, etc, the small motor will become stressed by the overall weight of the boat causing it to draw more amps and overheat. See what other people are using on similar boats to get ideas.
