Abstract
An improved hydraulic cylinder arrangement for a marine propulsion unit permits primarily effective tilt and trim movement through a compound tilt and trim cylinder. At least one first shock absorber valve is provided on a tilt piston and at least one second shock absorber valve is provided on a tilt cylinder that acts as a trim piston in a trim adjusted range operation. In another feature of the invention, a filter is disposed upstream of the second shock absorber valve.
