Service alarm system for a boat propulsion unit
First Claim
1. A watercraft comprising an internal combustion engine, the internal combustion engine comprising an engine body, a movable member relative to the engine body and a lubrication system, the lubrication system comprising a lubricant used to lubricate at least the movable member, a control system comprising a lubricant service monitoring system, the lubricant service monitoring system comprising a timer, at least one memory allocation, and an alarm, the timer recording an engine operating time value, the memory allocation holding the engine operating time value, an alarm unit responsive to output a perceptible alarm when predetermined engine operating time value limits have been reached.

Abstract
A service alarm system for a boat propulsion unit monitors a lubricant service life. The system informs the watercraft operator when the lubricant is no longer suitable to provide proper lubricating properties for the boat propulsion unit. The alarm system informs the operator by sounding an audible alarm or illuminating a visual alarm through at least one light. By informing the operator inadequate lubrication properties, the user can perform proper service of the watercraft to ensure safe and enjoyable watercraft operation.

- 1. A watercraft comprising an internal combustion engine, the internal combustion engine comprising an engine body, a movable member relative to the engine body and a lubrication system, the lubrication system comprising a lubricant used to lubricate at least the movable member, a control system comprising a lubricant service monitoring system, the lubricant service monitoring system comprising a timer, at least one memory allocation, and an alarm, the timer recording an engine operating time value, the memory allocation holding the engine operating time value, an alarm unit responsive to output a perceptible alarm when predetermined engine operating time value limits have been reached.
- 16. A method for determining when a lubricant no longer possesses proper lubricant properties, the lubricant lubricating at least one movable member within an internal engine, the internal engine being controlled by a control unit, the control unit comprising a lubricant service monitoring system, at least one memory allocation and a perceptible alarm, the method comprising the lubricant service monitoring system recording an engine operating time value into the memory allocation and activating the perceptible alarm when the allocated engine operating time value exceeds a predetermined value.
- 31. A machine comprising an internal combustion engine, the internal combustion engine comprising an engine body, a movable member relative to the engine body and a lubrication system, the lubrication system comprising a lubricant used to lubricate at least the movable member, a control system comprising a lubricant service monitoring system, the lubricant service monitoring system comprising a timer, at least one memory allocation, and an alarm, the timer recording an engine operating time value, the memory allocation holding the engine operating time value, an alarm unit responsive to output a perceptible alarm when a predetermined engine operating time value limit has been reached.
