greensix - what did you have to do to install them? obviously cut the fender but what did you use to cut it, and to actually attach them? any underside pics would be nice.
I used a Dewalt 4.5" grinder with a cut-off wheel. I taped up the fenders, drew an outline and got to cutting. There is about 1/4" of overlap on all sides so you have some room to play. I used 1/4" pop rivets to attach them to the fenders. You can see them in the close up.
I'll see if I can snap a picture sometime today of the underside.
BTW the new keyword to search on ebay is "boat vent". I tried to retrace my steps and "Seadoo vents" doesn't return much. Here is an example of the vent I have but in white:
