    Specs on Thru Hull Exhaust Tip

    Does anybody have a picture of what the Riva or Rude I guess exhaust tip looks like out before it is installed?

    I need to know the inner diameter of the pipe. and also it's length.


    Also Is it Stainless or Aluminum?

    Thanks

    Am I seeing a rubber washer or o ring between the two metal flanges?

    Does this go on the inside or the outside?

    Also with Jerry's new water box, Does it connect by a silcon coupler?

    Looking to have one machined by my bro (it's free!)

    How Long is it too Red Devil?

    The Riva thru hull flange is black annodized aluminum. The outer diameter of the flange tube is ~2.725". The inner diameter of the flange tube is ~2.350". The length of the tube from the edge of the flange to end of tube is ~3.30" long.

    There is a foam rubber gasket that (according to Riva instructions) goes on the outside of the hull. To be specific, one side of the foam rubber gasket is adhesive backed. The adhesive side is to be applied to the thru hull outlet tube/flange and then inserted into the hole in the hull. You are instructed to use silicon sealant on the retainer ring on the inside and loctite on the SS hardware screws that screw into the retainer ring.

    I'm not sure about Jerry's shorty box but I think Jerry mentioned that the Riva location and thru hull tube/outlet could be used. The thru hull kit uses a silicon tube/pipe to connect the exhaust pipe to the thru hull tube/flange.

    Hope this helps.

    Thanks prop, I appreciate it. This gets me a little bit closer to spec. I should think for a fabricator it should be no problem.
