To comfirm, I measured my old mufflers and a piece of exhaust hose.

good luck.
Man, I am scratching my head now. So the tip I need is a 3" diameter unit? Any idea how this unit attaches to the boat and the size of the pipe outside? Because I know the diameter on the outside of the boat is more like 4". I guess I will need to pull off the flapper and put a tape measure by it and snap a picture. I do not doubt what you guys say is true but I am seeing it from the outside and am confused...
If its not a competition ski boat, its always second best.
