trying to eliminate that annoying impact sound for gears that are well under the water and not even exiting it. sheepluva might want to look this over since this is modifying his code and should perhaps be part of the addSplashForGear checks, but hadn't had much luck getting him to examine it past year or so

# If not, a fatal error is set, cmake stops processing commands and will not
