Abstract
A method for controlling a trim position of a marine propulsion unit for propelling a watercraft has the steps of: sensing an engine speed; positioning the propulsion unit at a first trim angle when the engine speed is less than or equal to a first predetermined engine speed, the first trim angle being constant; positioning the propulsion unit at a second trim angle when the engine speed is greater than the first predetermined engine speed and less than the second predetermined engine speed; and positioning the propulsion unit at a third trim angle when the engine speed is greater than or equal to the second predetermined engine speed, the third trim angle being constant. A system for controlling a trim position of a marine propulsion unit for propelling a watercraft is also disclosed.
