Hey, Guys, I am brand new here and so-so handy. I have a 2004 50 HP ELPTO. I haven't run it in a year because the steering froze and the impeller is gone. Well, I fixed the steering but I am having a heck of time just getting going on the impeller. When I shift from N to F to R the action seems to move in the engine head but nothing happens with the shaft. Also, I cannot, for the life of me "uncouple" the shaft -- the lock nut will not move. Any advice? would really like to get this moving.
