I had just got started on testing lubricants when during a run I hit a USO. What ever it was it was solid. The Kintec nylon shear bolt in the rudder worked as designed (thanks Jan!). Only the bolt head remained.

When I got the boat back to shore I could hear something rolling around inside. When I opened her up, to my surprise it was one of the motor mount bolts (the one that I did not replace with a 4mm one).

Evidently I stripped the bolt hole in the motor, (when replacing the motor) after drilling out the opposite hole. This happened even though I was VERY careful. These bolt holes are not correctly threaded for this motor.

If anyone strips one of these bolt holes, I suggest to drill/tap BOTH to 4mm.

Looks like I have some work to do before I can continue... :mad:
