Well, I spoke with Centurion. Their customer service was very helpful. John Boncher, I think his name was. He thinks the vibration, engine lull, and the RMP deal is probably the prop too. So we'll see this weekend. John said the lull was a Over-Rev Protection that the engine has on it. As far as the ballasts go. We tried replacing the impellers once. Didn't work. John, said that once the Jasco pumps go bad they'll never work right. They are getting replaced with new pumps soon hopefully.
Lance, A little vibration IS normal, but the vibration I was having was pretty violent, like the entire dash was about to fall off. }
Mark, Please do let me know what they say about your cavitation/slippage deal. It sounds like we may have a similar problem. You can email me at
email@example.com">firstname.lastname@example.org if you want. Thanks.
We replaced the shaft and the strut just to be safe after the Folsom Rock incident.... so, I'm hoping that is not it. I should have mentioned that earlier.
Thanks for the posts guys.
