    How much space on exhaust side?

    Can someone with a complete RXP engine in a GPR hull measure about how much space there is from the exhaust manifold to the wall of the hull?
    And is the exhaust manifold easier to access with the wider GPR engine compartment?
    I'm basically wondering if there's more, less, or the same amount of space as the RXP engine in the RXP hull.

    It's really strange.
    • There is more room in a gpr with a rotax than with a gpr engine.
    • There is more room in a gpr with a rotax than a rxp/t with a rotax.
    • Strangely, you can get a complete rxp engine in/out of a rxp, but you "pretty much" need to remove the intake manifold to get it in the gpr, without grinding it in. You leave the exhaust manifold in place to remove or install.
    • A header would have PLENTY of room in a GPR with the rotax engine.
    I have my manifold off right now. I'll try to remember to get you a measurement.

    Forget the measurement, that's plenty of info for me Mark. Thanks a lot. Bottom line is I was wondering if there's more room to access the exhaust manifold than in the RXP hull. Thanks again
