    Aside from the torque tab on the motor you can eliminate steering torque by finding the right trim for the motor. I ran my 4 blade at the same trim setting as my 3 blade and it had a significant pull. Dropped the trim pin down a hole and the steering torque went away.
     
  4. Good idea trim and tilt really makes these boats come alive hell I gained 5 mph by putting one on

    the trim and tilt worked out great. its supper fast never seen a tnt work so fast
    boat has near 0 cavitation due to 5.5'' setback
    got more rpms but im turning that prop to its max
    I can get 26-28 topping out at 6000 rpms trimmed way up. at a decent trim 5500-5800
    jumps up on plane quick
    im happy but I know with a different pitch I can reach 30. but w.e. speed doesn't rule me. its for fishing. and running in a squirt of water

  9. If you are getting 6000 trimmed out that prop is perfect don't change it, like I have said before those trim and tilts make these small boat handle and ride 100 times better and they don't weight any more then a manual jp
