One thing to take a close look at also with the boosted ski is the valve cover gaskets. With the pressure that they make the gasket can’t hold the pressure when they get older and then you’ll have oil blowing out the gasket. Found out on my first outing on my 300x that I bought. New gasket with a little rvt fixed the issue but I still have the catch can issue. Hence why I bought the newer style to hopefully fix the issue.

[@watercraftjournal]

Valve COVER gaskets? There shouldn't be that level of pressure in and around the valvetrain. That's what a PCV is for.

[@Tommytakanawa]

$160 USD for a plastic bottle a hose and some hardware isn't exactly CHEAP bud.

[@jamesrollins8411]

Great video!

[@racerx2084]

A video on the difference of the round catch can on the kawis and the newer updated one on the later 300s n 310s would be great. I just ordered the newer style bc I’m getting some oil in my intake. Part my faught bc I think I had a little too much oil in engine. But I could only find 1 forum piece on this. They did a cut away on the round and it’s hollow. No baffles so as it still helps it’s not enough on the higher boosted 300s and 310s. I’m guessing the triangle style has some type of baffle? Haven’t seen a cutaway on that or any info on why it’s better other than it’s size.

[@watercraftjournal]

We haven't seen a cutaway either, but presume you're right.

[@radoadamov9201]

Great video as usual. I have one question if you don't mind. Is "Motul powerjet" 10w40 appropriate to be used in supercharged seadoos like the 4 tec 215 and the newest 300s? I am looking for the best available out there, thank you in advance.

[@watercraftjournal]

No. It's too slick for the clutches. Use XPS.

[@radoadamov9201]

@@watercraftjournal, thank you, I just watched your video regarding the oils. Will do that.

[@TheBradKear]

Just purchased 2 seafood gtr 230’s. If I install catch cans will it void my warranty?

[@watercraftjournal]

If you have to ask the answer is yes.

[@alexandretaborda4309]

Hi. My jet ski leaked a lot of oil. Today I was wiping off the oils. I realized that the valve that opens and closes is not firm. Is it possible to leak more than 2 liters of oil just through the catch?

[@espritmike]

So Kevin, if I understand you, the oil level in my two 300 sea doos (2019) should be at the minimum level of the dipstick when dead cold? It’s a pain and easy to forget to check when riding and I NEVER run them out of the water for more than a few seconds. Thanks, Mike

[@dproulx7380]

Do you feel same way with svho engines on oil levels and what oil do you recommend Manufacturer recommendations or should I use a synthetic???

[@watercraftjournal]

No, no and no. Literally "no" to all of those.

[@dproulx7380]

So no to using yamalube

[@dproulx7380]

You need to tell me I’m changing oil and plugs this weekend

[@lennyortiz1734]

hey question i have a 2023 RXT-X and i put to much oil and i wasn’t hitting more than 7600RPM can that be the case ? i took some oil out but have not test the ski yet thanks

[@mikestringfellow4501]

Do naturally aspirated SeaDoos need catch cans?

[@watercraftjournal]

No

[@graz9766]

Doesn’t void warranty correct ?

[@MarcM143]

Why aren't catch cans standard?

[@sea2sea2seevanlife92]

Good question.

[@watercraftjournal]

They are on supercharged Kawis.

[@gonridnponcho]

Emissions at idle and pcv to intake hose is less expensive than a catch can to manufacture.

[@Dan-qk4ns]

On Seadoos it will void the warranty as they are not emissions compliant.

[@Flybynight_2112]

@@Dan-qk4ns So Kawis that are supercharged are not emissions compliant ? The catch can come factory installed on new Kawis.

[@MassieDesign1]

So your saying a inline air oil separator is better than a catch can that vents, any certain separator you recommend or do you just vent out

[@watercraftjournal]

Yes. And no, nobody offers this kind of oil separator for PWC. You'll have to find a suitable one online and plumb it yourself.

[@Futurase1]

Not trying to argue whatsoever and I 100% agree with your explanation, but I have a 2020 RXT X 300 and after 35 hours I have ZERO oil residue in my intercooler and zero in my intake hose going to SC. I have taken both off many times to check and so far I have ZERO. Did the maintenance on friends 300's and 230 and all did but mine does not. I keep the oil level at half way up dipstick so never too full. I have a Riva catch can I have never installed and I understand their purpose and reason for using I just find it odd mine has ZERO.

[@watercraftjournal]

Exceptions do not negate the rule.

[@rafelos]

After 100 hours I pulled my intake off and found sludge in the intake. It gets all over your inter cooler and reduces efficiency and gets on the super charger impeller. Additionally it is being re-routed back in and "contaminating" the clean air the engine is getting. A catch can is a must have for me.

[@jessievelazquez3565]

Does catch scan works on the kawasaki 15f?

[@watercraftjournal]

See our video on non-supercharged skis and catch-cans.

[@StevenSynfulmindedVickery]

What about a BRAND NEW 2023 GP1800R that hasn't been broken in yet? Should I still install the catch can? will it affect the break in process or should I wait break it in then install the catch can?

[@StevenSynfulmindedVickery]

I literally picked it up today ha

[@watercraftjournal]

We’ve answered this exhaustively elsewhere. Catch cans installed at or before break-in are recommended

[@lukerapp2]

i have a 2022 wake 170 do i need a catch can?

[@jasontippmann208]

I got a 2019 seadoo 230 wake pro will that catch can work thank you

LOL, as long as you have the ski! Just drain it occasionally.

Hey Kevin, I just ordered a 2023 Yamaha FX Cruiser HO. should I install the RIVA catch can with filter on the HO engine? Will it benefit having it on a HO engine?

[@justorodriguez4742]

I have a catch can installed, my jetski is completely modified, 23lbs, cams, inyectors, etc. Racing/recreational, im running on e85 gasoline, is it possible for the catch can to collect gasoline vapors?? does not collect any oil. Every time I use it, it takes about 1/4 or a little more of the catch can of a very clear yellow liquid with the smell of ethanol, it does not collect any oil. Does anyone explain about this? Could it collect gasoline gases since the jetski was so modified? Or it could be something else that is happening. What if they are gasoline vapors? what would it affect? Thank you

[@watercraftjournal]

No oil in the catch can means you've got great compression and you're not producing excessive crankcase pressure. But if you're collecting this fluid, it's looking like unspent fuel vapors (as you diagnosed). High compression/boost will certainly have that. -K

[@justorodriguez4742]

@@watercraftjournal ok, my compression is optimal because when I installed the 23lbs I put new piston rings, rod bearings, etc. So yes it is possible that with good compression and high psi boost, camshaft, etc (90mph) it is possible that yes, the catch can collect some liquid gasoline vapors (in this case E85) ot domething similar that is not oil and it is also possible that the oil smells a bit like ethanol E85 because of this (when I measure the oil on the dipstick) ?? Thank you very much for answering my questions.

[@JimmieJohn]

Is the catch can necessary on the 2022 models? If so, should I request the dealer install one before I pickup? (I preordered a GTX 230)

[@watercraftjournal]

Yes and no. Your dealer is VERY unlikely to install aftermarket parts.

[@JimmieJohn]

@@watercraftjournal Okay, Thank you! I'll order and install myself. should be simple enough. It seems like this part is such a necessity that it should come installed from the factory.

[@cday6160]

Grab you a jpracinginc catch can.

[@JimmieJohn]

Why doesnt seadoo build with catch can?

[@watercraftjournal]

Because it has a crankcase PCV that routes through the air intake.

[@chrise.400]

@@watercraftjournal that doesn’t answer the question. The default PCV set up that routes to the air intake sucks. This is a well documented fact. The question is if a catch can is so much better, why not incorporate it into the OEM design from the factory?

[@ethanyork3037]

@@chrise.400 I believe all manufacturers have decided the extra maintenance step of emptying the catch can is not worth the performance/longevity benefits for the average consumer.

[@chrise.400]

@@ethanyork3037 turning a knob on a petcock valve is a lot of work? So better to dump oil fumes in to an air intake and have long term issues with other more costly components. I hear what you are saying, but if it is true than that is completely ridiculous and makes literally zero sense IMHO.
