And also remember... Pitch, Diameter and number of blades ALL contribute to your boats performance. Like Reelapeelin says.. get the one that does what YOU want it to do. Keeping in mind that constant overrevving or lugging your motor will contribute to a shorter lifespan.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God)

Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
