    Default Steering Question

    We have a 2014 Moomba Mondo and when out of the water the steering wheel at the 12 o'clock position has the rudder straight and true however when in the water cruising at around 3000rpm the steering wheel is in the 10:00 o'clock position to maintain a straight path. Noticed this over several seasons but I guess my OCD finally got the better of me.
    Is this normal?
    Fins all look straight so am guessing it's just prop rotation??
    Anything else to look for?

    Thanks and regards.

    Are your surf tabs both fully retracted? If one is slightly deployed, it can cause the boat to pull as you increase speed. This forces you to countersteer in order to maintain a straight path.

    2014 mondo doesn't have surf tabs just trim tab. I have the same thing going on with my 2015 mojo. It is prop rotation and you need the rudder slightly turned to compensate during higher speeds. Completely normal and only way to offset is to add weight to starboard side. If you upsized your prop the pull is more noticeable also.

    Thanks for your replies.
    I put on a slightly bigger diameter prop as we carry a bit of weight for surfing, that's probably made it a bit more noticeable then.
    Getting the boat level port and starboard helps a bit and gets an even wake for wakeboading, something I never worried about with the stock prop.
    Oh well, wishing for more sunny days....lake is 99% full.....

    If this is a big issue for you, maybe you should get something like the Cobalt steering wheel.
