It is hard to find pusher props in hobby stores, so often airboat guys mount the engine so it pulls. Apparently, simply mounting a puller prop backwards (curved side to the engine) does not do the trick for pushers, though I don't know why.

For glowplug engines, some carberators work better one way; since most engines are made for airplanes, it's often easier to mount the engine per puller-airplane practice. This would not be a factor for a brushless electric motor, but might be a factor for a brushed motor since brushed engines are timed to optimize one direction of revolution.
