    AR192 loss of power

    Here's an update on my situation. Got another new clutch installed this year. This one is running well after about 30hrs I also have a Fizzle y1000 with dedicate water line. However, when boat is cold the first start my RPMs go to 6000 then Always drop to 5000. The only time it doesn't...

    AR192 loss of power

    Yes. resolved but have burnt out 2 more clutches since then. 20minutes. 20 hours. Never at Wot and only baby'd the boat. Totally frustrating Went to another dealer and they said the first 2 replacements were not installed correctly. Well I will believe that after I get my boat back next...

    AR192 loss of power

    OK, it gets even better. The dealer finally tracked down the hot water in engine compartment to a crack in the oil filter housing. So, this will also be fixed under warranty. Do you think the SC clutch going out twice in 2 hours could be related to the oil cooling issue or more likely the...

    AR192 loss of power

    So, took it back to dealer and clutch is gone again - after 2 hrs! This time won't be covered under warranty. Not sure what to do at this point. Dealer told me that the engine has been at WOT 80 of the 220hrs and it's not designed for that. I understand that 80hrs at WOT without a BOV would...

    AR192 loss of power

    So, here's the update and it's not great. The dealer water tested and said the SC clutch was slipping so they replaced it under warranty. I don't think they lake tested it after the clutch change because it was hesitating on takeoff (5000RPM) or so. The dealership is 20minutes from the water...

    So I spoke with my tuning guy here up in Toronto. He said it was a custom mapping he worked on with somebody at Riva but couldn't remember the max RPM. Based on the top speed of 51-52GPS, I don't think it was over 8100RPM. After we deal with the cavitation issues, will try some more tunes...

    AR192 loss of power

    The cavitation burn makes sense. I am new to these jet boats and only got interested in tuning because of the heat soak issue I need to get the loss of RPM issue resolved first. Will go through the checklist and respond back after this weekend. At least we have the 2 new Sparks up there so...

    AR192 loss of power

    So, how long would that take to happen? The boat has always cavitated when I turn right :) I drove it really hard for 220 hrs until the tune last fall - then another 5-10 after the tune. I am sure that at least 50-70 of those hours are at WOT. I don't know the actual tune - it is a custom...

    I used a PWC performance guy in my area with a good rep. He did the fizzle install and the tune. I will check with him which one he used. He wanted to be conservative on the first tune. I suppose I should get him to transfer the license to me and buy a maptuner now that I bought 2 seadoos...

    Debug procedure: 1. Check air filter - 5min 2. Check supercharger clutch that can only spin one direction. - 5min 3. Change plugs $100 w tools 4. Check and fuel pump. 5. Give to dealer. It has 5yr warranty

    AR192 loss of power

    Would supercharger clutch cause variation in rpm or max out at 6000rpm?

    AR192 loss of power

    Thx for responding! Port is fine. I just had wear ring replaced to fix a vibration. Wear ring had a hole in it! I think this is a different issue. It was running 7800rpm and hesitating from 7200-7800 with no change I slowed down to 6500rpm. It was dancing from 6000-6500. Then I stopped...

    Yeah it was a hole in the wear ring. Fixed. Now the vibration is gone but there is a power issue. Boat engine is wavering rpm by approx 500rpm. Bleh. I wanna keep loving this boat but it's hard these days..

    AR192 loss of power

    Late last year I noticed hesitation on hole shot I was thinking it was a consequence of tuning to 8100RPM. So I would bring up rpm instead of punching full throttle. Now the hesitation is quite bad and in addition the rpms hover instead of staying constant. For instance if I am at 6500rpm...

    So, the pull out was not inserted tight. That eliminates the bubbles, but there is a major vibration over 2000 RPM. I will move this to another thread as it doesn't seem related to the mods at this point.

    SX 192 Mods

    Yes. agreed. Can water entering the engine compartment be related to the cavitation? The dealer checked my impeller when they re-commisioned and they also lubed the pull out port. I am hoping this is related to one of those things. Anyway, I will need to pull the boat today and back to the...

    Ar192. So last year I tuned to 8100rpm and had a fizzle installed. I launched yesterday. Boat ran fine up 51mph gps but was hesitating from time to time. I was thinking it was bad gas. After 3rd time hesitating from 8000 rpm down to 5000 I open engine compartment and there was so much...
