    that's what i thought...with the mods i have the boat hits 70 quite fast and as rpm increases it stay's on 70...thanks for the re-assurance

    No problem. Pick up an inexpensive GPS and you'll see you're probably way faster than 70

    I will test again today but I have a sport boat gauge on my T-X and I'm sure it goes to 75mph....my old OEM gauges only went to 113kmph which is 70mph

    Anything is possible, but as far as I know and from all of the units that come and go at our dealership, I've never seen a speedo that read over 70mph on a Bombardier ski or boat.

    Stock ECU it won't go past 70 unless reprogrammed.

    Riva ECU speedo will show past 70. I've posted in another thread with a video if you need proof.

    It's pretty accurate up to 77 then after that it's a little off. I've hit 81.5 and the factory speedo showed 83mph.

    Here is a video for proof... sorry about the quality, but thats the best I could do holding the camera with my left hand and trying to accelerate past 70mph. I have a cheap video camera and don't have a mounting system.


    You might have to switch to High Quality to view the speedo a little more clearly. Sorry, but youtube reduces the resolution.

    Hey, I believe you guy, I said anything is possible....lol. Never heard of the speedo reading above 70 if it was reprogrammed. That's great news!
