Re: Stus-List Inboard drive question
Mark, That is excessive. Prop, cutlass bearing or alignment. Did you check cutlass on the hard?

Re: Stus-List Inboard drive question
With a folding prop on a 30, you will get vibration. I'm assuming you have a two cylinder diesel? The prop is offset both vertically and horizontally - so it is not operating evenly. But, I don't have any wobble in the shaft - that doesn't sound right at all.

Re: Stus-List Inboard drive question
Hi Mark, I'm relatively new to the inboard world but would take the liberty of suggesting that ANY oscillation in the shaft would not be a good thing. Sorry to say that but I didn't see anybody else commenting. Just my thought. I don't think you'd lose a summer. Drop me a note and I could suggest somebody to help.
