So my dad and I got this boat a few years ago from a buddy and it has collected dust since we recently pulled it off the shelf. It needs some simple body work but the main concern is the motor.

Here's what I got now...

I hooked up a typical 9V AC adapter to the motor to test it out. It works, but it really doesn't make any torque. I could rub my finger on one of the spur gears and stop it rather easily.

I have no idea what kind of motor or ESC setup would work well in this thing. It's going to be the "rescue boat" for our Americas Cup boats and also to just have fun with when there's no wind for sailing.

Any suggestions?
 
Does the motor have any markings on it? If so post them and we will try to help track it down. You can also replace it with something more modern.

The 9V adapter you used most likely doesn't have enough amperage to power it properly. Typically, some 9V power supplies will run a transistor radio, but will not be able to drive a tape deck.
That motor was made for that boat, and with the correct power will run it well.
If you connected it to a 7.2V 3000Ma battery, you wouldn't be able to stop it with your finger.
Those batteries are very common in electric boats, and the speed controller is readily available.
I have a twin motor, twin batt boat, and that's what I'm running. There's NO way I can stop the motor by touching a gear without burning the skin off my finger.
 
Eddy, Someone wrote 37 on the body with a marker... and the bearings are made in Japan, but that's it.

I didn't think about the amperage. I just looked at the adapter I was using... "Sega Game Gear," HAHA. The output is 9V 300mA. I didn't realize the amps were so low. I just hooked it up to a 6 cell 2000mA NiCd and it did run stronger and faster. The motor seems to be in good shape. It pretty sturdy and spins freely. I'm just not familiar with how it should run and if it's just worn out. I think I might have expected more out of it.

I guess for now I could get a ESC and a good battery pack to try out.
 
The boat doesn't look like it's been used, so I doubt the motor is worn out. What you should do is get a good bearing oil at the LHS, and lube it. If it's been sitting a long time, the oil in the bearings or bushings will be stiff as grease.
 
that's a very very nice looking boat. that would be a very great looking model. i like the stern drive, very scale looking. wish i have a boat like that. who's the manufacturer of that boat? what's the dimensions of the boat? i think it's necessary in order for you and others to decide in what size of motor is good for that nice boat.
