    Flywheel are not stretch bolts, they're just not strong enough on the 4tecs. BRP now uses the stronger 12.9 bolts so you just have to hope they're torqued correctly :)

    There's been couple reports of the front bolt pulling through the hull on the 300s, seems to be quite rare though.

    You'll have to get that bolt area structure rebuild. Your ski is fine otherwise...

    He's ski uses SRX props not SRZ, it's not a direct swap.




    I think SRX has more material around the thread hub. Either way, I don't think your charger is big enough for 161 to make sense. ...

    77 mph at 9100 rpm oh boy thats a lot of RPM for that speed.

    How much boost does "rude2" put out? You need to be making power to spin 161 impellers. If you want top speed stick with 159.

    I...

    Stock RPM I'd do 3.5 but if you want to have a bit more margin if in the future you want to run higher than do 4. I don't think you'll notice any difference between the two.

    I did 220 hours on my original 2012 PX carbon seal when I switched to the new taller hat kit. I measured my used one and it was 0.2mm thinner than brand new seal. I own the alignment tool.

    Unless the floats on older skis are different I don't see how that would be caused by the float itself. It's just a wire with a ..well float at the top, it floats. It can't float more than the gas...

    One would hope so, T3 hull needs a refresh. The crappy part is we'll most likely lose the strong hull material and gelcoat for the weaker new generation stuff.

    I know you say this a lot but I think you must be using the wrong size screw driver if you can't get them secured. I use a screw driver that fits nice and snug, doesn't require much pressure...

    Compression test must be done with WOT otherwise you're dumping fuel into the cylinders and may hydrolock the motor in extreme case. WOT kills fuel and ignition when cranking.

    Just make sure you guys are talking about the SX4 13/16 not SXX, plenty of people have used SXX 13/16, including myself, either directly or depitching 13/18.

    SX4 = 4 blade, SXX = 3 blade

    We're...

    Maybe it's the angle but that carbon seal looks very thin. The angled part should be thicker, looks severely worn to me.
