Abstract
A system for determining an oil amount in a marine drive includes an oil level sensor that senses an oil level in the sump and temperature sensor sensing an engine temperature. A control module for the system is configured to determine that the engine temperature is greater than a temperature threshold, and that an engine speed exceeds a speed threshold for at least a predetermined time period or that a throttle position exceeds a throttle position threshold. If both such conditions are met, and a threshold drop in engine speed to an idle threshold is detected or a threshold change in throttle position to an idle position is detected, then an oil level in the sump is sampled with an oil level sensor. An oil amount is then determined based on the sampled oil level in the sump.
