Engine won't turn

My 40hp Merc refuses to turn (left or right). I added grease to the "pivot" shaft until it came out the top and bottom washers. It takes two adult to make it move. I bought the engine used and it had been sitting about one year (supposedly). Is it possible that the shaft is bent? Is there a set screw I don't know about? Other than this problem, it runs fine. Any ideas?

Re: Engine won't turn

At the bottom/front of the powerhead, there is a tube.It is between the transom mounts. It has an aluminum colored rod (stainless steel)running thru it, that attaches to the motor, with one bolt. Remove that bolt, and pull it apart. Now try to move the engine back and forth. If it moves free, let's start with that tube.<br />Where the steering cable goes into that tube,there is a big nut. Unscrew and pull back the nut. Pull the aluminum colored rod out of the tube. It should come out very easy. If it does not, the problem is rust inside that tube has decided it wants that aluminum colered rod forever. Remove the nut on the other side of this tube and slide it off. Note that this nut has a felt washer inside. This is to hold the lube inside, and keep the water and debris out.<br />Nothing but gobs of liquid wrench and hammering will free it (if you are lucky). This is where they usually sieze up on your motor.<br /><br />Once you get this aluminum rod out,see if you can move the steering wheel. If you can turn it freely, you can take a shotgun bore, and clean the inside of the tube. It needs to be rust-free and spotless before you re-install the rod. If you don't get all the rust,it will sieze-up next year. Once you have it cleaned up, grease the heck out of it, and re-install the rod. The nut with the felt inside should be clean and dry. I use gasoline to clean all the gunk out of the felt. This felt has to be able to hold fresh grease to complete the job of sealing it off from the elements.<br />I hope this helps. If this is not where it is (you have the rod out, and the steering wheel still wont turn), the helm or cable has frozen.,and will need to be replaced.

Re: Engine won't turn

Thanks for your reply. I am not sure if I explained the problem correctly. The steering controls from the helm to the control tube (?) work just fine. This system operateds with little effort.<br /><br />The problem is at the vertical shaft that is part of the transom mount; and the engine turns (L & R)on this shaft. Darn thing is tight, tight, tight! Hope this clears up any confusion. Thanks for your assistance!<br /><br />Scott G.<br />MN

Re: Engine won't turn

Usually these things freeze up in the tilt tube. Your problem is also common. You will have to separate the engine from the transom bracket.To acomplish this you will need something to hold your motor up and away from the bracket.Remove the two large bolts that screw into the exhaust housing at the top just under the lower cowl and take apart the lower motormounts and the engine and gearcase and ex. hssy are then free .Pull out the swivel and clean it completely.A nice days work.

Yea buddy...A good day's werk!<br />And I'm sorry, I didn't get into that part of it, as the problem you are having isn't the "norm".<br />Hondon's advice is the way to go.
