'56 Johnson 15hp, throttle linkage stiff

[RobKorn]

The linkage/shaft that runs from the advance plate down through the shroud to the gears, about 10" long, mounts vertical, through rubber boot...<br /><br />It is very stiff, cannot get it freed up. Tried loob/soak with penetrating oil, took off all stuff connected to it and still can figure out how to get it out of its "mount".<br /><br />How do I remove it without breaking it? Help.

If you disconnect the link at the mag. plate, and remove the brass strips held with two screw's at the top of the verticle shaft, it will lift straight up, and out of engagement with the lower gear. To free up the throttle linkage, it is best to remove the mag. plate, clean, and relube, same with the throttle handle. Both these point's when dirty, and dry, can really bind up the throttle.

I tried all of that... after everything was disconnected from the shaft it is still very stiff.<br /><br />It will not lift out of the mounting point... that is why it is stiff.<br /><br />What you are saying is that it SHOULD lift right out.. that means the stiffness is also holding it into the mount...<br /><br />Bigger hammer? I should be able to just tap it up and out right?

Hi Rob,<br /> The vertical shift rod is a slide fit into the gear that transfers the horizontal twist to vertical. The gear itself has a nub on the underside that twists inside the mount on the motor's carry handle bracket. All of it can be taken apart. Originally, the T portion of the vertical shaft that slides into the gear was a nylon piece, somewhat prone to breaking if forced. Possible that someone cobbled something else into the shaft that is fitting tight.<br /> Use a good waterproof grease when reassembling. Check for burrs, wear, etc.<br />- Scott
