I have an 85 Force . How do determine the shaft length? I recently purchased this engine. I measured the from the bottom of my boat to the top of the transom and found 26 inches. Before installing my new/used engine can I determine the shaft length? Also, does anyone know the dry weight of the 85 Force. I am placing on a 18 ft center console that had a 60 evinrude. The Force appears to be much larger. My boat is rated up to a 140 HP
