A quick look at the gearboxes since I had the hull pulled off to inspect/clean them after a lengthy couple of days of hard running and kicking up dirt and dust. Surprisingly there was VERY little dust or dirt intrusion that entered through the hull seems or drive shaft hull pass through whole. Given the amount of dust and dirt I was working hard at kicking up into the tracks and sprocket the inner hull and gear box should have been covered heavily in dust.

The red grease is something I started added during the taking of these photos and not factory. In fact the gearboxes did not have much factory lubricant on the gears. The gearboxes were decent running before, but now properly greased they run butter smooth and super quite.
