I didn't know the 34 came with a tiller option. My 1978 34 had a wheel, as does every other 34 I've ever seen (about a half dozen or so). Interesting.
Given that the wobble corresponds to RPMs, I would not guess it's a tiller or rudder grease issue. I'm no expert, but it sounds more like a prop shaft strut or cutless bearing issue. Did you by chance have a dock line sucked into your prop before the vibration started?

A cursory inspection does not show any adjustment or easy bearing replacement. All bolts are tight. There is some slack, maybe 1/8" when testing the tiller by moving back and forth at the dock. Has anyone else experienced this? Is there a known easy solution short of replacement? Should I be concerned. This seems to have gotten worse over the years.
