ABSTRACT:
A number of embodiments of lubricating systems for small watercraft that might become inverted and wherein a lubricant reservoir supplies lubricant under gravity to a lubricant pump when the water pump is operating in a normal upright condition. An air return line extends from the lubricant pump back to the reservoir to pump air which may enter the lubricant pump back to the reservoir. Arrangements are provided for insuring that air cannot flow from the lubricant reservoir to the lubricant pump through the supply line when the watercraft is inverted and also for precluding lubricant pressure in the air return line from acting to force air back to the lubricant pump when the watercraft is inverted.
