Claim Text:
1. A method for controlling a trim position of a marine propulsion unit for propelling a watercraft, the marine propulsion unit being driven by an engine, the method comprising: sensing an engine speed; positioning the marine 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; determining a second trim angle at which the marine propulsion unit is to be positioned when the engine speed is greater than the first predetermined engine speed and less than a second predetermined engine speed, the second trim angle increasing as the engine speed increases, the second trim angle being determined independently of a speed of the watercraft, the second trim angle being greater than the first trim angle, the second predetermined engine speed being greater than the first predetermined engine speed; positioning the marine propulsion unit at the 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 marine 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, the third trim angle being greater than the second trim angle.
