I second using wd40. It’s also hard to find actual fogging oil here or anywhere in the tropics.

So I swapped on the factory plate and did a lot of tweaking. Mounting, testing, removing, repeat. I finally got the ride I was after. The ride now is smooth with zero porpoising. The oem plate is...

pre 2010 had some head cracking issues which seem to be limited to skis that ran in cooler waters. Pump bearings absolutely need to be replaced and upgraded without fail. And the ogura supercharger...

what specifically is bad? The throttle position sensors and idle air valve can both be replaced. Even a hole in the throttle body could be patched and machined. I’ve never seen a “bad” throttle body...

The one port flushes both. You can change up the plumbing to flush the intercooler separately late if you like but the stock setup does both. One thing the manual does not emphasize but I’ll repeat...

Picked up a new pair off of eBay for $35. I know Jerry was saying it was one of his favorite new features when the 2016’s came out. They really do make a world of difference with long term rides. The...

Finished building the harness and it has completely cured my hot start issue. I made the harness completely plug and play which was super convenient. No switches of buttons and is fully automatic....

If it was located on the west coast I would be quite interested.

I use a 50/50 salt away mix for deep cleaning. I just fill the flush port directly with about a gallon of the mix and let it sit. After about 24hrs I flush it out. Works great for heavier build up....

Getting really tired of seeing these carbon seal posts. The bellows is like a rubber spring. If it heats up too much the bellow softens and no longer holds a tight seal against the hat. When it...

The jet pump liners can swell with salt water and cause the impeller to seize. They can be replaced fairly easily.

Not sure exactly how many hours were on this engine. The bottom end looked very good though from a thorough visual inspection. Oil had probably been changed once I would say in the lifetime of the...

Here’s the thing. There are a few major issues on the 250X that should be addressed if you decide to keep it (which i would). Pump bearings: you’ll need to upgrade the pump to the newer style with...

And just note: be very careful when opening the supercharger and follow the procedure carefully. It’s easy to damage the housing.

You can separate the case and remove the rotors. Just don’t remove the gears or you’ll have to re-clock them. There is a YouTube video from Kawi on disassembling these ogura superchargers. Once you...

Ski runs perfect and I can also comment that the bedlined keel is working just fine with no ill effect. I do have the typical hot restart problem that I’m addressing now. Waiting for Sean’s feedback...

Seadoo used ceramic clutch washers in their early model superchargers. I believe in 08 they changed to a new all metal clutch. The ceramic clutch washers were supposed to be able to handle the heat...

Very true. Pretty much all brands NA skis are fairly low maintenance (for a ski) and very reliable. I’ve heard the Yamaha mr1 engine wasn’t so great but the 1.8 is a solid engine. The kawi 1.5 brp...

Bold new colors for 2021...

With a factory service manual I would have to say they are all about the same to work on. Each ski will have things that are easier and harder than the other. Supercharged skis are plenty fun but if...

I don’t think anyone ever said that we didn’t like our ultras. You just received some realistic first hand feedback of what to expect. If you have the option to go test one out than do that and see...

The end is in sight!

[QUOTE=Chris288;3087996]13 years later there still isn't a better offshore hull than the ultra,,, it most certainly is the king. which ski do you think surpassed its rough water prowess ? There isnt...

Just found it. Its referenced as crankshaft side play. Spec is between .002-.0094 with service limit at .017. That's a really big range! Suffice it to say, my .0035-.004 is well withing factory spec....

Yeah, she has the faster ski. 10 more HP doesn’t make up for all the extra weight and the deep hull design.
