I am still on the original plastic u-joints with the exception of the one I had to modify with the aluminum shock cap. It is still working great. With regard to the u-joints needing water I understand but this is not a race boat. 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.

This this is another way to fix eliminating the u-joints using flex shaft as long as you have the tool to square each end off and machining out a square on inside both hex seen a few people do this back in the days

Yeah I can square off the flex shafts. I'm just not sure there will be enough "flex" in those shafts for tight turns. And if so it would put a lot of strain on the steering servos. But I like the idea of the flex shaft in the hull between the motors and transom. Thay would eliminate the heat issue I get on the U-Joints in the hull.

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.
AUX on/off switch. Pump.

Couple trailer pics. I built the trailer by hand myself. I even made the fenders. LOL. By now I'm sure you all know about the CEN Racing F450. Took me months to get one. It tows great. I'll see if I can upload a video.

So a long, long, long time ago this thread started out with discussion on AMPS outboard motors.....I found this out when I was Googling for information on this type of motor
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
Why would I be doing that.....?

Very very sorry for your loss
Hello, very sorry for your loss. I would like to give the little outboard a new home and a few bucks of course to the family, I sent you a private message and hope to hear from you. Bob
