Meirgerner, I also have a 2009 H33 but mine came with the 3 blade 14" prop (part of the Mariner Package). On the upside I can say that I love it! The boat stops on a dime and has a great reverse, additionally, there is very little or no prop walk. On the downside there is a lots of drag. At 5 kts it audibly vibrates and can be heard throughout the boat (I run with the transmission in reverse). I have considered a vari prop just because of the vibration and reduction of drag (I would also like the .5 knot increase in speed as well) but it is hard to justify the $3000+ cost to do either of these. Especially when the Admiral gives me "the look" for suggesting it... LOL
