Abstract
A lubricating system for an outboard motor having a lubricant delivery tank mounted on the outboard motor and which is replenished by a pumping system from a separate lubricant storage tank contained within the hull of an associated watercraft. The circuit for controlling the pump includes a trim angle sensor that is mounted on the lubricant delivery tank for preventing operation of the pump when a trim angle change would incorrectly indicate a need for the addition of lubricant to the lubricant delivery tank.
