    Default High thrust vs normal thrust kicker

    What is the difference between a "regular thrust" and high thrust outboard motor? I have been told that it is just the propeller, four blade vs two, but I can't help but think there is more to it than that.

    Its a different ratio lower unit and has more distance from the prop shaft to the ventilation plate so you can swing a larger diameter prop... yamaha high thrusts are 3 bladed props that are larger in diameter and with less pitch

    The Yam T8's also run a different gear ratio and the motor can turn 500 rpm more than a non High Thrust. The T8 is a great kicker, the T9.9 is good too, no electric tilt nor electric start tho.

    The T9.9 does have electric start with a manual back up (sort of-Yamaha gives you a starter cord and instructions how to use it with the purchase). It will also charge your batteries when it is in use.
    I have one of my SeaSport and it will push my boat up to 6 mph depending on the wind. Love it.
