[QUOTE="Zum, post: 223630, member: 349"] His motor just isn't powerful enough to spin the bigger prop,with all the weight. I don't think nothing is wrong with his motor,probably the 14 pitch has your outboard towards it's lower rpm range. Your rpms went up,spinning the smaller pitch prop,so your speed stayed the same with a nicier holeshot. If you had a real big pitch(15+) and it was lugging your motor(hurting it)a smaller pitch in the proper rpm range would give you better top end and performance. Do you use a tach? Has to be the most important tool when dealing with props. [/QUOTE]
