Abstract
The present invention provides a system and method to adjust the quantity of oil delivered to the cylinders of an internal combustion engine of an outboard motor. The system includes an oiling system to distribute oil throughout the internal combustion engine. The oiling system has a pressure sensor connected between an oil injector and the internal combustion engine to sense oil pressure and produce an oil pressure indicative signal to an electronic control unit (ECU). The ECU is configured to monitor the oil pressure indicative signal and modify a modulated oil injection signal delivered to the oil injector.
