    Yes they do. Ive assembled motor so that it dont go too high, there is one bolt hole left and it stays that way😂. The boat starts to go little sideways when going too high thats the "dont go higher" mark for me.
    I do all work just by hand, have how you say very sensitive touch/feel in my hands. Have to trust those.

    Next todo list. Just need to change hub for correct splines. Its rubber cushioned.

    The reason it try's to go sideways is prop walk. Your steering tab is out of the water. This is where torque tab works, and / or a longer skeg....
    1 hole left, but your already using jackplate.
    To have props haft level with boat means it is up 7 inches already. 20 inch mid put cav plate level with bot, centre of shaft is 7 inch from cav plate..
    Plut you have 5 or 6 inches of setback too, so can go higher, depends where bullet is at full speed.
    Camera time . Only way to tell is to see the video of the gearcase at full speed

    As for engine gearcase not being central to hull that is correct, it should be off set slightly.
    This counteracts prop torque.
    Even st slow speed if the motor was aimed straight ahead and steering locked off eventual the boat would turn full circle.
    Single outboard should be offset about 3/4 inch, more with big motors.

    What prop is that on the latest pic ?
    That don't look like srx.
    Looks like a modified prop, strange blade shape.

    When running high the prop will try and steer the boat. This gets put right with a torque tab on the skeg. If running normal and cav plate level or buried the small trim tab under cav plate does the same job.
    If nothing on skeg the the prop will be walking when on surface.
    Fitting a tab on the skeg is easy. Either weld on or bolt on. It goes on driver side on your motor. Like small aerofoil just to help keep motor running straight without prop walking too much...
    Stops the need to keep having to turn the wheel to go straight ahead.
    also give a tiny bit more speed as keeps thrust in a straighter line.

    Hey Phill,
    Ive got little offshore boat that goes at best 57kn and in rough weather it can manage little less speed but over 50kn, do you really think that im not on the map with these things?

    No need to get ****ty. You asked if your missing something.
    It was You who mentioned about height and steering.

    Being as you have not fitted torque tamer/tab to the skeg yet running high makes anyone presume you don't know about them or making one side of skeg flat and otherside convex to help with steering and prop walk effect...
    For testing at high speed and running surface these should be thought about and implemented .
