[QUOTE=maxepower;9813336]You can do two things or both.
First you can change the o-ring to a tighter one. Some are using the clear or the blue o-ring that goes inside the Tamiya shocks, and last put that green-slime on the o-ring and outdrive shaft and that should help also. I also put a very thin coat of silicone sealer on the gasket also.
Try these it just might do the trick!
