    Is it bogging or blowing out, when planing off?

    ???? Sorry new at this, would assume its bogging. Bow points to the skyr but i do not get a sudent rev in rpm's. the more rpm's the higher the bow goes. i have it trimed all the way down. The dealer said i needed a dolfin fin on motor. The 357 is a 15 ft boal seems a 50hp should make it fly?? sorry about the spelling...

    Yes a fin will help but is a band aid covering up the real problem, whatever it may be. Try another prop if you can borrow one and see what it does, balance your load and tackle also. Are the rpm where their supposed to be @ WOT?

    the 357 is set up with batt's, gas tank and oil tank in the stern, wish i could move the batt's forward but there is no place to put them the way the boat is made. Question on prop? i know that a lower number on the pitch increases the rpm's and is supose to give you a better hole shot, but am i loosing thrust at the same time? if the stern is to heavy should i go to a higher pt prop?
