I have carried out a repair on the trim ram and am ready to reassemble the tilt/trim hydraulic system. It consists of two rams and a pump/reservoir (apprx 100mm dia extenally bolted to rear of engine mounting), I believe the entire assembly is an after market addition to the engine. Question is what is the correct procedure for refilling with hydraulic fluid and flushing / bleeding the system. Many thanks for previous assistance and thanks again in advance for any suggestions.
