    For a project, im after a small marine gearbox for a 1.2 Litre engine, about 5k RPM max.

    Marine gearboxes in the uk, the cheapest I can find is 300quid so
    Im Wondering if anyone's ever built a gearbox or somthing that would allow reverse

    Any suggestions??

    I had that idea some years ago. I havent seen my drawings in some years now though.
    I was going to use sprockets and Motorcycle chain's and a seperate Cluster gear for reverse. I thought steel or aluminum Plates with some kind of a pan for oil.
    You still need a Slider, similar to the Clutch dog in the lower unit of an outboard to get the Reversing.
    To answer your questions, No I never built it.
