    Don't waste your time with those little dremel sanding wheels.

    Get some of these to put in your drill

    I don't want to f%^k up & take too much material off, so I'm only going to use the dremel to do the detail work near the edges. Once that's done, I'll taper it into the rest of the shoe with a drill sized flapper wheel like your pic.

      I finished up all the blue printing on my grate & transom plate on my SHO & was getting a nasty buck at ~69mph on every run. I've run the same angle on Jim's R&D plate(shimmed .095 on the rear) with the same prop I had on today & could easily run 73+ before opening up the shoe section of the Riva grate to mate properly with the TP. It's definately stuffing more water now. I did the testing on a stock ECU, & since I was bumping the limiter the last time out with this setup with a 83mm ring I had the 82 in this time. My rpm was 7600 with a true 155 YS-DF 15/22 which has way more root angle than the Riva DF, so I was kind of surprised to get a buck with this prop. Hopefully the fix is simple...more rpm & a bigger nozzle ring. I'm going to try it tomorrow with my R2 ECU & 85 ring.

      The SHO doesn't buck & hook violently like a GPR when it overstuffs, but if your not prepared for it you can still get hurt. Just a warning for anyone wanting to try this mod on a SHO with stock ECU.

          I wonder if some robot put down the sealant on that. It has to be about the straightest use of sealant that I've ever seen and we go through some silicone.

              Guys if you look closely on the 3M tubes of silicone they have a production date on them. Make sure you get a new tube and not one thats been sitting on the shelf form a year or two. I noticed at west marine they had some really old stuff there And it wasnt setting up after days after application.

                  Jerry,

                  Did you see any significant changes when you did these mods?

                      Thank you for the info i did this mod and i believe it help because in that open space the silicone was broken and this looks more secure.

                        I can't tell you for sure because the ski was dangerous & almost unrideable at top end speeds. I did notice improved hookup from opening up the shoe though. I switched back to an unmodded Riva grate & the problem didn't go away. Using an R&D grate almost cured it, but after more riding I discovered it still had some quirks in the handling...like having the back of the ski dart sideways when crossing the wake of another ski. I ended up having to replace the modded transom plate with a stocker.

                        I've never heard of any of these issues from doing this mod on an FZ though.

                            From what info is on this thread it works well for a FRZ but, not safe to do it on the SHO!

                              Quick question, does the FZR have the same cavities/molding voids in the top half of the transom plate? Looking at mine it looks too thin there to have a void. Mine has sealant bulging out all the way around the outside of the plate so I do not see a reason to pull it and reseal unless there are voids on it like that FX transom plate has.
