Re: new prop question

dogtoy,<br /><br />What kind of prop did you buy?<br /><br />1. New or rebuilt?<br />2. Stainless vs. aluminum?<br />3. Cupped vs. non cupped? Cupped props have a lip at the trailing edge of the blades.<br />4. Brand?<br />5. Same size?<br /><br />Did you hit something requiring the purchase of a new one??

Re: new prop question

Hello,<br /> Sounds like your prop is out of balance,Damaged or both.Take a look-see for dings/bends or missing metal.Is the prop pitched too high for the boat?An over-pitched prop will cause vibration at low speeds.Also check the trim ajustment tab(fin)on the cavitation plate.Is it straight?May be why your pulling to one side..
