I have a 1984 35-hp Evinrude with a manual shift lever on the left side of the powerhead. It will only occasionally go into neutral. I am sometimes (rarely) able to get it into neutral when the engine is cold, but not otherwise. The lever won't "stop" in the middle neutral position; it just will flip between forward and reverse. It's like the middle position doesn't exist. <br /><br />Neutral is good to have. Any ideas? Thanks.
