Hi everyone.<br /><br />the tilt and trim cylinders are all leaking on my 1980 115hp. i wanted to know if anyone knew the part number required and also had any helpful hints. the part number for the end cap is 320788.<br /><br />I bought a manual but it says if the hydrolics have a problem take it to your mechanic. Clymer Evinrude/Johnson outboard shop manual.Covering 50-235HP 1973-1987.<br /><br /><br />any help would be great.<br /><br />cheers<br /><br />ethan
