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.
    Has anyone successfully opened up/bored a 2012+ FX SHO/SVHO transom to 160 yet? With the huge tunnel and 87 nozzle it does seem like a good move - But definitely not worth a STUFF!
