    Doesn't Schiada96 make underwater gear too?

    Now schiada96 is the exception to my above post. I know for a fact that he makes everything he sells. Nice stuff too!

    But is a 1/2" rudder in a BAH unsafe? Is it illegal with NJBA or IHBA?

    The following is from the NJBA rulebook on what is legal for Top Alcohol Hydro, you'll see that 1/2" is the MINIMUM. I would call Ron Braaksma at
    909-866-3298 ... he'll send you in the right direction.

    4. Neutral Device – A devise to allow engagement and disengagement “at will” of the propulsion device while the engine is running.
    5. Prop Shaft – The minimum prop shaft diameter through the back of the strut is 1-1/8”.
    6. Rudder – Minimum 1/2” thickness of the clamshell.

    I've got 2 outboard rudders that I'd like to get rid of. Both are 1/2" thick. PM me with an offer if interested. Here's the longer of the two:
