I was coming back from a day on the water about 1/2 mile from the marina<br />running @3500.4000 rpm when the boat took on a strong vibration. I felt it at the sametime the engine noise seened a deeper pitch & louder<br />no increase in rpm's (nor did it loose rpms) I never felt any kind of strike of any object... more that something came loose. I shut her down tlited the eng up, no visible prop damage.QUESTION <br />do these symptoms sound like a prop \<br />hub issue<br /><br />something esle?
