I just changed the prop and adjusted the WOT stop on my 1981 90Hp Evinrude.<br />Changed from a Alum 14" X 17" prop to a 13 3/8 X 17 S/S prop. This I dont see as an issue and the engine now runs smoother and doesn't shake all over the place.<br /><br />I also adjusted the WOT stop and throttle cam yoke as the carb wasn't opening fully and took the slack out of the throttle cable.<br /><br />But now the engine will rev all the way with the warm up lever on the forward control, but won't rev past 2000 at WOT.<br /><br />I've checked all the linkage set-up as in the Clymer Manual and alas it covers a lot of models and the one it claims to match mine has a different picture for the linkage explanation.<br /><br />Please Help.....
