[dippasan]

Woodsy
Accutech in Dover did the props and they look great. I had the same vibration last year as well. Seems more like "U" Joints or gimbal to me and I think it's only in the port engine/drive best I can tell.
According to mercurymarine.com there's no mention of "timing" the props. (See attached instructions)
Formulaforum.com info shows nothing definitive about it either

Thanks
