I have a 1975-1977 85hp merc. Yesterday I had replaced the impeller. I went fishing today and found out that I now have for gears....<br /><br />Forward, forward, and forward.<br /><br />Reverse is forward. Neutral is forward and forward is forward. <br /><br />What did I do wrong and could a novice like me fix it or should I take it to a shop?<br /><br />Thank you,<br /><br />Chris
