I run it as a scale model so I rarely give it full throttle and I am running back and forth is a small space in the canal behind my house so they are only running "dry" for a few seconds at a time.

However, the metal U-Joints I have coupling the motors to the drives in the hull do get hot. So far no real issue there, they just feel hot when I pull the boat. Today the boat was running awesome but one of the cooling lines for one of the ESC's came off so I was filling the boat with water as I ran. Luckily I was on my real boat running the RC when I noticed it and was able to grab it. I have a bilge pump system I am working on now so if this happens in the future I will know and the water will be pumped out.

As for the U-Joints in the boat that are getting hot, you can see them here.

Here is a quick post on my bilge pump system. This is a little pump I got from Amazon and a little rig that plugs into the AUX on your RX so you can turn it on and off from your TX assuming you have at least 3 channels. I did not mess with an auto system. I simply hit the AUX on the transmitter to check for water. It works very well. I poured about 12 oz of water in the hull and the pump evacuated it in about 30 seconds. This particular pump does not need to be submerged. It is a diaphragm pump so it will suck from well above the water. I mounted it under the ESC tray and ran a rigid tube to the back of the hull. Then a short dump overboard.

Why would I be doing that.....?
A buddy of mine just passed away and I'm trying to help his family dispose of items he had acquired over the years...including one such motor!
I'm not sure if the motor was ever run, or if it was it doesn't appear to have been run much.
The motor turns really freely including the outboard prop.....it does have some damage to the housing portions, which from what I read was a typical problem for this type of motor.
I'm trying to figure out how to get this sold to a new owner so that he/she can enjoy it and the family can get some bucks for it.....I'm on this site, FG and RCG but am not sure if there is much call for the motor on any of them
Thanks in advance for your help
