    Sandman,

    I found a good powerhead for you. I have almost gotten it all torn down (1 darn exhaust cover bolt left that is being stubborn!)

    I tested the bore, and it is true, with very minimal wear. Well within spec. It was a 125 psi motor.

    Ill soda blast the powerhead tomorrow, assuming I get that last screw out of course. Hone the cylinder and paint it.

    You will be back on the water by spring!
