420890481, 420881992, 420881991, 420881990, 420893563 are the same part, 420893563 being the latest revision.

OEM ones in good condition are pretty rare. For $349 you can get aftermarket billet replacement drop in.

Here is how my 300 charger fit into a 260 PTO, I did not touch the nozzle and this is how I've been running it for 3 seasons.

You need to compare them all at the same time, too many variables that can affect the results.

EU 95 octane will not fly with that charger, that's only 91 in north america. If that's all you can get you should probably go with the 135 wheel.

If you're dead set on running that charger...

Dunno about speakers on jetskis, especially a PX, kind make them look like they're growing tumors.

Unlikely it's a leaking intake manifold. If it was it would most likey not idle great and would not reach full rpm due to boost leak, it would not be an intermittent issue.

First thing I would do...

That sounds like the grate is pushing in more water than the slowing down pump can process creating mini stuffs.

"Master mechanic" reusing piston rings on a rebuild sounds strange but here you go (from 2012 service manual):

For those of us that can't see it in person just yet here is a nice walk around of the new RXP in high quality. Not in English but still shows just how nice this ski is.

The only useful thing from your posts are the boobs in your avatar.

At what RPM does SVHO go positive pressure? Stay under that RPM and you'll be fine just cruising. You also have knock control, if for some reason something knocks, which should be able to safely...

For a $1000 I would forget fast, you'll be lucky to find something that isn't a total POS and actually runs reliability enough where you're not scared to go a mile away from the dock.

Save up and...

Found couple pics of the purple with 2up seat, ski looks way better in this configuration. BRP marketing in charge of this should get an ass kicking for allowing that 1up to be the flagship look....

2up definitely looks better, it should be the standard configuration or allow people pick the seat at purchase time.

Wonder if we could get some kind of a group buy going with a dealer to get a...

Have you guys seen this graphics builder?

You an actually select 4 levels of graphics, you don't have to go all...

That reasoning makes no sense, they should have allowed people to pick the seat they want in the base price or just include both.

I was hoping for improved rough water hookup from my '12 PX, going backwards would be a bit disappointing. Maybe Riva will come up with a improved grate. How do you miss this when making a race ski...

Looks like both 300 and 230 superchargers are getting a revision, new part numbers.

OMG this is ridiculous!

If you want to re-use them than do so. If you don't want to re-use them than don't. If you want to know why BRP changed their procedures call BRP and ask, good luck.

Nice looking machine!

I believe those are just fins on the wheel that start at mid point of the wheel and grow larger towards the outer edge. You're just seeing the very tips of them, they're larger under the housing.

So you're saying a bolt that was stretched will have the same clamping force the second time it's stretched even further?

These aren't space grade materials, it's probably the cheapest stuff they...

This thread is way too long.

Service manual has been saying NOT to reuse head bolts for the past 10+ years, that's a pretty good sign it should not be done.

If you're modding for higher...

I've watched so many videos over the last few days I lost track, but I'm 100% sure I heard it.
