Sea Doo 4-TEC throttle body lubrication

[full_tilt]

here's a question for Sea Doo techs or those with extensive experience in maintaining late model Sea Doo's

what is a good lubricant to use on the throttle body quick lubrication kit...

how is WD-40 for this purpose... what would be other good lubricants to use if the bombadier lube is not available

thanks

My preference

I prefer to use an anti corrosive, water displacing, lubricating penetrant called "Cosmoline". That's just my choice because like many, I'm not anywhere near a Seadoo dealership. I use this on my naturally aspirated 787cc Rotax engine. I see your question pertains to the 4-TEC engine, which is completely different than mine. Hopefully, one of our 4-TEC owner/members will chime in here and give you their opinion.

Do not use WD-40 I was told by the service use a XP lube only.

Wd-40...

While I'm not a big fan of the WD-40 brand lubricant, I know its water displacing capabilities have been compared as 2nd to none in the drag racing community. It's widely used to dry out moisture inside electronic ignition systems.
As for it's use in the Seadoos, I'm not to sure. Your 4-Tech engine is a state of the art engine. It's components, although made simply, can be very sensitive to petroleum products. As diselman has pointed out, it may be a good idea to ask a dealer. With one thing in mind. Asking a dealer which brand is better, the opinion you receive is going to be biased. He wants your business. It's like asking a republican which democrat is the best to vote for. His answer......"none"........:rofl:......The political humor is free!
FYI....I just went into the manual on the 1503 and I didn't see in any of the maintenance sections where the throttle body needs any real lubrication on it. If your making reference to the spring and cable area, it's suggesting a light coat of grease. Because everything Seadoo has a brand of their own in lubricants, oils and greases....trial and error on your own may be something you'll learn as you own the craft over time. When I use grease's on my Doo for things like the springs, I use a silicone type grease.
If you don't use the recommended lubricants suggested by Seadoo, then you are experimenting or looking for alternatives that will/can fit your application. This can do good or harm. You don't know until you try them. As with any petroleum product, the gumming or lacquering effect as the residual hardens, is going to be a problem, no matter where it's used if it's not cleaned and maintained on a regular basis.
Dieselman, if you have first hand experience with the cons on using WD-40, please elaborate. With the popularity of this product, I'm sure there are many of forum members who use it. If I remember right in a post you and I did on synthetic verses mineral, you have a lot of experience in this field.

Seadoosnipe on the new ones there is a port under the seat to lube the throttle body from the inside not the springs or the outside. And must be done every 10 hours or so and must be a XP-S lube. This is in the manual now what is a XP-S lube? I asked and like you said the dealer said there brand and NEVER use W-D 40 so I use there lube. XP-S Lube. Description. A multipurpose lubricant that prevents rust, corrosion and moisture intrusion. ... sounds like WD-40 to me but for now I will use there's since I bought a can $11.00.

Thanks for the info!

I did a little bit of research on this lube and the most I can come up with is that it's a synthetic product.
The 2005 shop manual recommends that you spray in and out and all around with the XP-S lube, P/N 293 600 016. I've done lots of reading from different areas and found that there are some mechanics that use a standard silicone lubricant for preventing moisture corrosion, while lubricating the surfaces. As everyone knows, silicone is very slippery and is synthetic.
If the Seadoo (BRP) manafacturer recommend you use a specific product, then I stand by them. This is your investment and if you use anything other than what they recommend, especially during warrantee, then you could be liable for the repair bills.
My research will continue on this subject for one reason. Does Seadoo actually have a company set a side thats dedicated to R & D (research and development) on all their oils and lubricants? I think not. Do companys buy standard products already used for other purposes and bottle them up, put their logo on them and sell them as their recommended product? Yes, they do. I'm not looking to discredit any of the Seadoo product line and I'm sure, they DO have products set out or designed specifically for them. But there are hundreds, if not thousands of owners who don't live near a Seadoo dealer, where they can find access to these products and must come up with alternatives. In the Seadoo manual, it states that if you don't have access to the Seadoo brand mineral/synthetic oil, you can use an equivalent, like the Quicksilver brand, low ash, non NMMA certified oil for your injection system.
In my life, there have been times that I've paid $40 for a product, only to find another product for $15, read the label and it had the exact ingredients and/or ratio's as the more expensive product.
I do, myself use the Seadoo brand, synthetic oil in my jet pump along with other brands of Seadoo products. But sometimes I do feel the need to compare when it appears a monopoly is in progress. That a person will fear using something else and not ride until they can travel 100 miles to the nearest dealer, just to get a special (that I think sometimes isn't special) oil or product.
I am not a certified or trained Seadoo mechanic and the above paragraphs are only my opinion and right of debate. I do not advocate that anyone use anything other than what is recommended by their PWC/boat dealership.

:agree: I totally agree with you Louis! I have found in my past experience that if a warranty issue came up and the manufacture's product wasn't used it could become issue as in injector oil or pump oil. Spray lube that dissipates over time or is washed away shouldn't be a concern, but the same similar type is acceptable.
As far as WD-40 goes, I use it in the pump and Impeller area as a wash down and coat against salt water deposits. Also a light coating over the engine area again as a protectant against corrosion. In the water craft area I have found it to be almost useless as a lubricant as it dosen't have the staying power as other syntheic or petrolum products. This is based on my 10 yr racing career of Kawasaki Stand ups, in salt/fresh water from trial and error.
