I've been running this new boat for about a week now with no issues except for the shaft coming apart (I guess theres a reason it comes with a spare) While lubing the shaft, I put a tiny kink in it at the coupler end, which also ovaled the hole in the rubber boot. It now has a little vibration and its taking in a small amount of water. Was wondering if that boot was the cause of the water getting in. or could it be the servo rod boot? Do they sell the boot by itself?
