    Default 1996 30A3 Tohatsu Gearcase

    I have a 30hp tohatsu that will not stay in forward gear.Does anyone have a good diagram of this lower unit? I have replaced dog clutch,spring, pins and even tried to reverse the clutch without any help. I can put it into forward and use my foot to turn prop while holding drive shaft by hand.It seems to make a noise and then slips. Thanks

    That's normal. It's supposed to ratchet in Forward.

    Would you explain how it ratchets and still has torque to put the boat on plane? I'm confused, since reverse doesn't do this. Thanks

    A ratchet works in one direction only.

    I understand the concepts of a ratchet. What my question is (how can or why can it ratchet by turning it by hand but not while it is underway)? Thanks for help..

    If it's a RH prop setup, then turning the prop clockwise, it will ratchet. Not so if turning it CCW.

    Yes, if you turn the driveshaft CW, it should lock. If you turn it CCW it should click.
