    Well Calhoun Marine is only doing Mercury outboards at this time. Still on the look out for someone that can cut a Yamaha 70 hp mid down to a 15". I have a 20" mid section with a F50 4-stroke lower unit also 20" that will need to be cut down. Using a Pro50 tilt trim unit. Building on a powerhead at the moment.

    Hey Fast Fred, is the long shaft pro 50 bracket longer or different than a short shaft? If so, what is the mod you have to perform to make it fit on a Stinger?

    Fred.
    As per Powerabout do you have a part No. and know of anyone who may have some for sale. Have been told that these are no longer available. The 31M part book shows 568206 being the leaf plate assembly and 560442 being the leaf plate.

    I wonder if the same as a CCC?
    I wonder if E-tec V4/6 reed blocks are same width, I guess Chris Carson would be the man to ask
