Update June 24: The engine runs smoothly, but the hydraulic trim tilt is malfunctioning, maybe due to pinched cables. It is probably an easy fix for the electro-mechanically inclined. Mercury 2-stroke Mariner 50hp (SN. 0A741227) with 550CCA battery, hydraulic electric trim tilt, recent piston compression (125, 125, 120), new switchboard Cames with several tanks. It can be viewed at the Royal Victoria Yacht Club, Cadboro Bay.
