    Angry RXT and shorty install question

    quick question how long was the coupler from the shorty to the exhaust tip?

    It looks like 6 to 8 inch coupler is needed. I know whre this is going so

    Wise cracks or sexually comments welcomed if you answer my question,

    Scott, I used a 6" silicone coupler with double clamps but a 4" or 5" would work okay too.

    2 3/4" ID. I took the left block off off, put the coupler on the waterbox, clamped it tight. Put clamps for thru hull part over the coupler and don't tighten down. Spray coupler with windex. Put the waterbox in the hull and push the coupler over the thru hull part. Fit the jpipe in, strap the waterbox down, tighten the j-pipe, finally tighten the rear coupler through the holes under the block off. Re-install the blockoffs.

    What you do is tighten the coupler on the shorty exhaust exit. Put the clamp for the tip loosely on the coupler. Remove the OPAS blockoff plate on that side of the ski. Stab the waterbox coupler over the tip and then reach in thru the OPAS hole with a socket on an extension to tighten the clamp

    You can also take off the blockoff in the tunnel...remove the nozzle for room to work and pull that blockoff off...point the clamps so you can reach from there and go for it!! The little tunnel blockoff is easier to take off and put back on. Of course, if you have long arms or a little guy to crawl into the ski then do it from the inside...

    Right now it doesn't matter Iam having trouble finding a marina/boat store that carries marine grade 2.75 inch exhaust hose.

    first question they ask what do you need it for?

    I might need to make a trip up to Salem MA or some place on the web
