    28zx toe out?

    My brother is taking my boat east today. We stuck it on the trailer yesterday and last night during final prep he says to me.... I swear the left drive is more left than the right. I measure it up and sure enough the drives are toe out by 3 or so inches. Before we square this up is there any reason for this extreme toe out?

    3".... that ain't right...

    I can't imagine more than 1/8"-1/4" being necessary

    is something bent or broken?

    From talking to my performance boat shop neighbor, if you are spinning the props outwards you want the drives set about 1/8 to 1/4" closer at the trailing propshafts than the transom assemblies. The opposite if turning the props inwards. This accomodates for the drive flex at speed to make them parallel.

    You need the toe in or out depending on rotation, without it the drives oscillate the same way a road vehicle does without toe in. It does away with the oscillation and keeps the slack out of the steering.

    Nothing bent, nothing broken... I might have 50 hours on the boat. The hydraulic steering and tie bar was set up like this by Donzi.

    My only blind guess is they had a tie bar set up for a big block boat then never adjusted it. Props do spin in if I recall correctly.

    If your props spin in I would set it toed in 1/4" and see how it likes it
