Hey guys, my names David. I just registered with seadoo forums and hope to be a member for many years. I have a '03 GTX Limited Supercharged and I am going to do the service myself since the stealership is booked up.

Just a quick question, I am going to buy the K&N equivalent Oil Filter and it only comes with one o-ring. Is that all I need?

Also, what oil can I use safely other than the Sea-Doo XP-S 10W-40 Mineral. I live in Australia, so an easily obtainable oil would be good (eg a major brand)

I purchased 3 NGK DCPR8E plugs like the book says, but the sticker on the ski says DCPR9E? Will the 8's be ok?

Thanks guys.

Oil type........?

Sorry to have missed this thread but it's a good question.

You do not have to use Seadoo oil for your 4-TEC. Although many die hard Seadoo owners would use nothing but the XP-S oils, you can use any brand of 4 stroke oil that bears the API designations that are equal to or exceeds SG, SH or SJ. Your viscosity should be 10 W 40.

The idea here is to choose one oil and use it for the rest of the engines life. All oils have additives in them. The idea of changing oils is that you change the properities of the engines use of these additives so that you may shorten bearing life.

Stick to one type oil after your change.

BTW, I'd not use a filter with only 1 "0" ring. Your suppose to have 3. I've never physically worked on this engine but if the seating surface of the oil filter has 2 rings that are embedded in the casing and there is one that comes with your filter, then that will be o.k....the manual states that you should have 3 but that you'll not often change 2 of them. :cheers:

Not to disagree with you snipe, but I noticed Kirbz seadoo is supercharged. If this is the case I would highly recommend that you stick with BRP 10x40 Mineral oil unless the ceramic washers in your supercharger have been replaced with metal ones.

If you do a forum search for 'ceramic washers' you will get lots of hits and quickly understand why it is best to stick with this oil. In a nutshell, other oils seem to cause the ceramic washers in the superchargers to fail.

Hope this helps!

Can of worms......

I knew that post would open a can of worms......:rofl:

Your always welcome to disagree!.......that's why it's a forum. We just want to be nice.........LOL

The problems with the superchargers when they first came out wasn't actually the ceramic washers. The problem developed when users switched to synthetic oils, probably recommended by the dealers who knew no better. Seadoo's have used synthetic oils from practically the beginning.

Ceramic is the best insulator type material ever made. It does not retain heat. NASA uses ceramic in the shuttles because of it's thermal properties. Used with mineral oil in the supercharged 4-TECs, you couldn't beat a better washer for minimizing heat. But, with the danger that was found from using synthetic oils, they had to change out to steel. They found the synthetic oil would, slowly deteriorate the ceramic. This would cause blockage in the oil passages and lead to supercharger or engine failure.

Now, BRP oils.......my recommendations to use which ever oil you wanted as long as it is a mineral oil came directly from the operators manual for his year and model engine. The engine is a 4 stroke engine, just like our car. But as with different engines in cars, turbo's, turbo diesels, gasoline, fuel injected or carbed.........all may use the same viscosity oil but probably use a different API designation. The designation for that year SC (and maybe all SC or SCIC 4-TEC's) was SG, SH or SJ. You can not use this oil in the 4-TEC's without the supercharger, it uses a different API classification and viscosity.

The number one oil used by racers of the Seadoo 4 TEC engine is AMSOIL. Their oil has been proven in modded engines for many years. You can go to their website and find the type oil you need for the type Seadoo engine you have. They also make the 2 stroke oil........but to expensive for my blood....:cheers:

I didn't know that any mineral oil was ok with the SC and SCIC engines. Good to know..this will save me tons of time and money cause there are no dealers close to here. Im gonna switch to metal washers when I get my SC rebuilt...im dew for one in 25 hours. I guess I will then switch to synthetic oil. Thanks for the info.

You won't notice any difference in the oil for the type of use, except for a $$$ spent. It's a 4 stroke so it's not like it's gonna be better on plugs or anything... and the oil gets changed more often so you won't benefit from it lasting longer, under adverse conditions.

hey guys thanks for all the help. Matt, its actually quite ironic because our supercharger clutch has just died at 85 hours. I was searching for some more info and it brought up this post. I did end up putting the recommended oil back in.

Im told that we may have not received the updated washers since we bought the ski second hand (14.4 hours) and the dealer may not have fixed the issue as part of BRP's recall

Im also told that the engine has to be removed and it involves over 10 hours labour so Im not looking foward to the repair bill.

Repairs.......

If you have access to manual, you'd see changing out your washers on the supercharger really isn't that hard. About 2 hours of work time. You only need a few tools and about the mechanical knowledge of being able to remove the heads on your car and putting them back on........

After working on engines for so long, I realized that if your gonna keep anything motorized, you better learn to work on it or before you have 10 years on it, you'll have paid for it twice!..............:cheers:
 
so snipe, Im happy to do the work myself, ive done the timing belt etc on my car so I should be able to manage the task. Im concerned because the dealer says the engine needs to come out to confirm that the ceramic hasnt broken up and gone into the oil pump. What are your thoughts on this?

The 'new' version washers are the ceramic coated metal. Are these the correct washers?

Thanks in advanced
 
I don't know who told you that you "CAN'T" run Amsoil but I think BRP would tend to say you could if you wanted to. Check out post 4; those are the requirements that came straight from the Seadoo Owners manual for maintenance of that year supercharged 4-TEC (I haven't seen a supplemtal on this). Their only requirement in a 4 stroke oil is the API designation. Which is common in all 4 stroke motors.

It is true that if you have deterioration of your ceramic washers, you'll need to make sure none of the particles are lodged inside the internal porting of your oil system. They will normally melt away (deteriate) over the course of time, caused by the synthetic oils (you should be using mineral). If you've been running the mineral based oils with the ceramic washers, you should have nothing to worry about. They should still be intact.

The type washers they are using now?.....I couldn't tell ya. I haven't looked up the part on it. I was under the impression that the first revision was to stainless.........If they are still using ceramic coated, then whats to say it won't deteriorate either? :cheers:
