    Thru the hull (stock outlet)

    Removing the stock exhaust outlet and installing block off.

    I have looked at this and have scars from scratching my head.

    Do I loose the big nut looking thing on the pump side?

    Also the block off:
    How is it held in?
    Do I need to remove the pump?

    loosen the nut on the inside, turn it AWAY from you...The nut holds itself in because the 90 degree elbow is threaded...YEA, yo8u will need to remove the pump to get better access...

    Here is what I did with mine...

    ...and no issue with it at all...

    Danny,

    You think your set up would work with a shorty waterbox?

    Also...did you end up covering it with a block off?

    funny thing is when you are at speed, its quietr than a regualr rear exhaust...and when you get on it, all you hear is air.....

    The riva block off goes inside the hull and the stock nut screws on it in the tunnel. You have to take all the stock stuff out but reuse the plastic nut.

    I don't mean to contradict anybody but I just installed the Riva plug in the stock exhaust location and the plug is installed from the outside.

    The nut and plastic washer are removed from the pump tunnel and the elbow and rubber washer are removed from the inside. You will have to remove the pump to get enough room to work and the cured silicone has to be removed. The rubber washer is fitted to the plug and inserted from the outside and the plastic washer and nut are screwed on the plug from the inside and be sure to use silicone.

    it doesn't matter... take your pick.. personal preference and aesthetics... the nut and plug can go either way.. nut on the inside or nut on the outside

    This is how I did it as well.
