Tiller Retention Pin
I experienced the same thing. The darn tiller falls out if you put any forward pressure on it. I noticed in the manual (yes, it is poor but it answers most questions if you study the CAD drawings) that on the CAD drawing for the rudder, a lock pin is shown (though not supplied). When I looked at the top of the rudder (actually the SS housing that the tiller slides into), I noticed a hole predrilled to nowhere, located about 3/4" forward of the rear edge. The tiller did not have a corresponding hole. I slid the tiller in, drilled a 3/16" inch hole and put in a SS Fastpin (3/16" x 1")in. I secured the fastpin to the tiller with a loop of shock cord so I don't loose it.I have attached the image. If I was to do this again, I would drill the hole in from the side. As it is, the square tiller is stuck into an inverted "C" channel (the SS upper portion of the rudder). The pin is only supported on the bottom by the tiller wall. I would like to see the pin go through 2 sides of the support and two sides of the tiller. This is not possible with the pin entering from the top as there is no "bottom support".Tough to explain, and probably unimportant as this has no load bearing at all, so the way I did it is probably fine.See the image to make a long story short. Write with any questions.
