Well folks it seems I'm the newbie on this forum and all forums seem to be a bit different ,so bear with me please. My question is in regards to an Evinrude 18hp 1967 vintage. Having just purchased a 14ft v bottom aluminum that has this motor on it. It runs fine, after a carb fiddling, but the issue is with the shifting. Reverse is perfect but forward wants to chatter and not engage. It will engage fine with engine off and started. Lower end lube looked fine with no particulates, but I changed it anyways. Suggestions? As an also note, I have visited this site many times as a guest and found this forum to be truly what a forum should be. Thank you for that and for being such a great group of folks.
