[C320-list] Transmission Problem

[Warren Updike]

I'm not an expert on trans and mine (Hurth) isn't the same as yours, so here
goes. If you rule out the prop, check the throw range of the shifter at the
transmission. It's very important that the neutral, fwd, and reverse
positions are very close to spec. 
Once underway in a calm, protected area, detach the cable from the shift
lever and manually shift the transmission while the engine I running noting
how far and where each position is. Are you still getting the "bangs" when
shifting and once in gear? If not, perhaps the cable isn't positioning the
shifter accurately: not moving forward or back enough to fully engage. If
you are still getting "bangs" there may be some excessive wear in the box.
I know on my Hurth transmission there are two pivot points in the shift
lever (on the transmission.) There is a specific throw distance in each
direction for each pivot point. They say it is very important that these
limits be reached when shifting. 
Perhaps you can find the manual for your transmission to get the similar
specifications.

My transmission is going into forward with increasing difficulty. The lever
moves fine, and I've replaced the cables twice in the lat 18 months, but the
problem is getting much worse. When pushing the lever forward, there is
little or no propulsion. We thought it was the two blade folding prop
failing to open, but checking the prop in and out of the water indicates it
works fine. Perhaps the clutch? When it does engage, it does so with a bang
(again causing us to suspect the prop), and sometimes with several
intermittent bangs at random intervals. I have little doubt that I've abused
it through the last year or so of this happening, but it's now becoming a
safety issue that must be fixed.

 

Anything sound familiar here? All thoughts and recommendations are
appreciated.
