+1 on Mikey Hoyt's point.. Windstar is an '85 33-2. same gen, very similar design to 35-3, and only a little smaller.
My new Gori 33-2 prop is 16.5" X 11 RH, per Gori's recommendation. OE Martec was stamped RH16DX10P-3 The 2 lblade fixed I used briefly may have been 17" and it worked fine. It was either bigger or more steeperly pitched.

Note that we also have the 3GM30F engine with Kanzaki transmission. Flex-o-Fold has sold me a 16 x 12 prop (on its way from Denmark as I type this). Should Dave be checking Cutlass bearing, the keys where coupler is attached to shaft, etc? Sounds like something is normally in alignment then once out gets reseated by pulling back on the shaft (reverse) and then pushing shaft forward.

You either have the wrong pitch or there is something wrong with the engine (throttle cable, etc.). If there is black smoke at 2600 RPM it is most likely the pitch. If the pitch is too great, I'm wondering if the prop is cavitating which can cause vibration. Also, a 16" diameter sounds large for a 35 MK III. If the blades swing too close to the hull, that can cause vibration. I seem to recall that if the blade swings closer than 15% (I think) of the diameter from the hull that will cause vibration. I had a 35 MK II and a 14" prop was marginal. Gary S/V Kaylarah '90 C&C 37+ East Greenwich, RI, USA
