Is My Motor Mounted Too Deep???

    i've got twin rooster tails that come off my extended transom from either side of the motor. nothing i do trim-wise does anything to help. seems like the cavitation plate is buried too deep when up on plane and i'm not getting what i would expect fuel mileage wise. would bumping the motor up one hole help or do I have something else going on?

    sorry about the link. the video was bigger than the max allowed and i have no clue how to shrink it down.

    I have the same issue...and plan to raise mine a notch or two. It was a stab in the dark as far as running depth, as my boat had never floated. The brackets can throw things off a bit too, making it hard to pre-determine where it needs to sit.

    yup to low need to raise it up a hole or two. you should be able to see your Cavitation plate when running.

    My motor was too low. Raised it.

    HUGE improvement.

    Is there no other reason a boat would do this?What is the down side to having the motor to low other than probable poor fuel economy.

    Slower speed as well as the poor mileage.

    Only reasons this would happen is something is wrong with the hull or something dragging on the motor.

    What kind of improvement did you get?Speed, mileage?
