    I posted this over in the boat building forum before I realized that there was a jet drive forum. Maybe someone here can provide some helpful insights:

    "I am brand new to boat building so I thought I'd plug in somewhere and get a little supervision from people who know what they are doing. Thank you in advance for any input!
    I am building an aluminum 1452 jet jon Powered by an Evinrude 40/35 hp jet.
    The purpose of this boat is for duck hunting a shallow gravel river near my home. There is very limited access so this boat will be hauled in by ATV in most cases which is why it's going to be so small.*
    I've been able to find every piece of information I need to do this build except... transom angle.*
    I'm under the assumption BTW that 0° indicates a perfectly vertical transom in relation the the bottom.
    considerations: the splash guard will simply be an extension of the roof of the jet tunnel and will extend back 6" or so to cover the leading edge of the intake similar to a wooldridge tunnel"

    14 degrees is the industry standard. All outboards are designed for it.
