    Through hull exhaust, remove and block

    Hey all, sold the RXT the father-n-law, and doubt they will want to hear the noise. What would you recommend for blocking the hole, beside re-glassing it?

    will the block-off plug that you put in the original hole not work? I don't know, just asking...

    I think the stock exit is 1/4" smaller than the thru-hull. I'm looking to do the same thing in the near future.

    Worth looking into. I figured I would be using some ultra black silicone to fill in, but I wonder if the gap would be too much.

    Lowes sells a red blockoff plug that I used to block off my original stock exhaust outlet. They are different sizes available and have the words "don't stand too close" stamped on them. Might see if one would work. Looks cool.

    Just slap a 4-tec performance sticker over the hole... done deal

    I would just leave the fitting in place... and cap it on the inside with a pvc plug

    GTXX, your right. The grey Riva plug that comes with the through hull fits perfect, all I have to do is dremel small holes for the 2 nubs to fit into. I ordered another 72mm nut from Jerry (part# 274000224) to secure it. The only thing now is to decide which will be on the outside, the nut or plug. It looks like the nut will cover the 4 holes as well, plus be much easier to install, but uglier
