Seadoo RX di

[Ric SA]

Hi all,

I am new to the forum and to jet skis.

I just bought 2 x Seadoo RX di wetbikes.

Now i see numerous posts and info on the web that the motors are unreliable.

Please give me some info, as i am now really in a spin that i made a mistake to buy these wetbikes.

Was there a RX di in 2004, as the dealer says it is 2004 models and i dont se any info on the web on 2004 RX di?

Thanks.

Welcome to the forum.... Don't get your spirits down just yet. You might have a good bike. If you look on the back, right hand side of your hull, you should find the hull number. The last 2 digits are the year model. But, it should be the 2003. In 2004, they went to the RXP model.

When you take this ski out, you'll know if you got a good one or not. If this thing runs right, it'll scream like a banshee.... I've been told, a good running 951cc, direct injected engine is a hot runner. It's just that there have been so many members come in that suffered major problems with the air compressor.

The injection system in these are two part. First, you have the fuel delivered by the fuel rail split seconds before it's being charged by high pressure air to inject it into the cylinders. The biggest problems with them is troubleshooting. The system is so complex that you might find yourself replacing several things before finding the problem.

But, don't be worried about it till you ride it........:cheers:

Hi,

Thanks for the reply,

I am buiyng them from a dealer, so can take them out before collecting.

I am getting a 3 month warranty, but in South Africa that doesn mean much.

The numbers are as follow if i have the right numbers and do they indicate anything to you?:

- ZZN51477L304
- ZZN51480L304

Ru shure that you are buying RX DI's and not RXP's because as snipe said in 04 there was no RX DI's. If they are in fact RX DI's you may want to do a vin check to make sure your skis are legit.

Your going to need to pull the seat off and look at the motor. Your HIN numbers above show that they are 2004 models. The only problem is they did not make the RX DI in 2004. The only direct injected (DI) it could be from 2004 is the XP DI. Or, if it's the RX model, it will be the RXP.

The RXP is a 4 stroke engine with 3 cylinders. The XP is a 2 stroke with 2 cylinders. So, look inside the engine compartment and look at the motor. If it has 3 plug wires, it's the RXP, if it has 2 plug wires, it's the XP DI.

There should be some body markings on it too. what color is it and do they still have the original graphics and paint on them. This is usually the easiest way to identify these things.........:cheers:

 

[Ric SA]

Oh crap, i am an absolute idiont, they are XP di....

Ok, so now that we have figured out they are XP di, can i be a bit more relaxed about the motor reliability and issues or not really?

Damn this is difficutl to figureout if you new to this pwc thing.

Thnaks so far for the help, it has given me more insight in the day i have been here.

 

[Ric SA]

No feedback or comment on the XP di motor?

 

[96seadooxpBC]

dont have near as much experience as snipe or any of these guys, but the fuel injection system is the same on these skis as the ones you originally thought, or mistook them to be.
there not always bad as snipe said before, they just run a complicated system, i think the most complicated they've made. if they run well your looking good.

[96seadooxpBC]

ie. take them for a spin, look inside, check for corrosion buildup/signs of moisture on the electronics, for example a roll over, could potentially screw the air compressor. they should haul ass, get up right out of the water, there running good i dont see why not, unless you want a ski thats easier to trouble shoot on in the future..

 

[Ric SA]

Thanks for the info, as per previous reply cant take them for a spin as they are with the dealer and there is no place nearby to take them to.

Had a look at them, and they are well looked after, no scratches, damage or anything i could see, obviously the internal i can see or inspect and that is the chance i take.

The dealer however do give a 3 month warranty on the second hand skis, so that should be some comfort or not really?

 

[96seadooxpBC]

ahh sorry about that, i didnt catch that snippet. hopefully seadoosnipe or one of the more experienced guys will chime in when they wake up over there in sunny florida haha! but if the dealer is offering a 3 months warranty that is some solid reasurrance, and i do know if these are in good shape, these skis haul ass. id say go for it man, just get that 3 months of warranty in writing ( obviously ) take another good look in the engine bay, i mean a good one with a flashlight n all, and start them up ( if you havent already ).

cheers mate, goodluck! let me know what decision you come too. :cheers:

 

[Ric SA]

Thanks bud, really appreciate all the help and guidance!

Personally, I would insist on test ride prior to purchase warranty or not. A test ride will tell you alot more than a visual check. Does it rev smoothly?, does it accelerate? Does it start in water? (many times a ski will start on trailer but being direct drive, will not start in water), Check impeller/wear ring clearance and damage (You need to get under the skis with a good torch/light to shine through the pump), Check motor mount wear (grab hold of the motor and pull from the side), Check for corrosion around electrical plugs (any corrosion will cause problems sooner or later) If you do a search there is a prepurchase check list somewhere here.

A good ski will be a lot of fun, a dud can be a nightmare.

:cheers:

Got it right...

Sounds like he pretty much got it right.

It's just so complicated that when something starts to weaken on it, you will spend big bucks till you find the problem. Or, using the shop manual, spend days trying to trouble shoot.

Like 96seadooxpBC said, if you have one that is running right, it's a screamer. But, if you have one that's been pasted together by someone, your liable to find yourself replacing a lot of stuff before you get it right.

There are two different injection systems that Rotax uses. The RFI (rotax fuel injected) system, which is an injection system that basically has nothing but the fuel rail, fuel pump, and electronic system that works it all. The DI (direct orbital injection) is on the high pressure side. The fuel pump on this set up cannot overcome the compression of the cylinder, so it's got the added compressor that works in unison with the fuel pump and electronics.

So you see, it's the DI system we're talking about. Not the ski model, like XP, RX, GTX, ... or any of the other skis running the DI motor. It's the system.

I hope this helps you understand it a bit better. But a test ride is paramount before you pass the money. I would not allow this dealer to sell this with the 3 month warranty. The reason is because if you do have a problem, he'll want to try and fix it. This thing could be in the shop for 6 months before they finally find a fix for it...........:cheers:

 

[Ric SA]

Thanks for all the help and info guys,

I will see what i can arrange with the dealer, maybe take them out the weekend, but i am not to sure they will allow this, in SA everyone is sceptical of scams and so on....

I will keep you guys posted.

 

[seadoosnipe]

Easily understood...

From your position, I can see that. What is good, the guy is willing to give you a 3 month guarantee. If you get in writing, that if you take it out and the DI system is not running the ski correctly, they must give you the option of getting your money back or a repair.

As long as you got the right from the dealer to get the money returned verses them only wanting to put it in a shop for repair, I'd not sign papers for it. This is a screw job. You can't pay the big bucks on something you never got a chance to see demonstrated or rode yourself.

Would you buy a brand new car without taking it for a spin? I don't think so.

 

[Ric SA]

Yeah I hear what you saying, and will see what they willing to commit to.

There is some comfort in the fact that they are one of the biggest boat and jet ski dealers around, so i would hope and think they would not want to tarnish their reputation by selling something that is not 100%.

But again, you newer know and it always is a gamble.

 

[seadoosnipe]

Reputation...?

Here in the US, reputation actually means mostly nothing anymore. Reason being is, there are so many people wanting boats/PWC's that they don't really care because they know there is another "joe" standing at the door, waiting to get in.

But, it seems you got a pretty good, informed idea now of what your looking for.

For this model, you really will need a shop manual. You don't need one for your specific ski, just the motor. And the DI 951cc was used in my skis through several years. So, just as long as it's the same motor, it'll work for ya......:cheers:

 

[Ric SA]

Do you buy these manuals form the dealers or over the internet or what?

 

[seadoosnipe]

We have them!...

We have them here in the library. If you have the use of pay pal, you could sign up for one month, go into the library and find your manual, or any other ones you might want, download them and print them off to books so you can take them into your shop.

After you get what you want, cancel your subscription. It's like $10 american dollars. One is easily worth that. If you download two, then you got one from free. You can download them all if you wanted to.

So, check into the premium services. You can stay as long as you want to support the forum but you acutally only need to sign up for a month to get all you need to maintain this DI system.

If you do and have problems navigating the library, let me know. I'll help you out and make sure you grab the right one. :cheers:

 

[Ric SA]

Thanks,

Must admit, you guys are really helpful, unlike some other forums i participate on for some of my other hobbies.

Forums....

I know that to be entirely true. Before I found this forum in 2007, like you I had checked out some other sites. I had a hard time finding an answer to my query and when I did, I was pretty much pointed out that I was kinda dumb for not knowing the answer. So, with all the arrogance, I looked elsewhere. That's when I found the Seadooforum. After finding the answer to my question, I hung around. I guess the administrators liked my help to others that they asked me to moderate.

In choosing to do this for them, I made a promise to myself that no one in this forum, regardless of status (premium or junior) would not be treated like I was in the other forums. Everyone here is important.

The manual will allow you to school yourself on this system. For the most part, your 951 engine problems can find a solution with our forum mechanics. the manual is for you to have the ability to do the prescribed tests with the ohm readings and pressure testing in the even you have a problem in the direct injection. This would be the easiest way for you to have enough information as to what you've already done before coming to the forum to ask a question.

For all DI motors, I always recommend you sign up for at least a month to get this manual. It'll pay for itself in just learning how to do the simple yearly maintenance. If you decided to go with the Clymers version, you will be short changed. They are not complete. The BRP version is the only one you can use to actually tear the motor down to the crank and put it back together...........:cheers:

 

[SEADOOSICAL GAMES]

the di motor seams to run pretty decent but i have seen on other fourms that when they do have a problem its usually a very costly one ...point being the one i have ( 2002 rxdi) the guy i got it from took it to a dealer to have the motor rebuilt and they gave him a bill for 2800...this was all caused because of a faulty inline water line connector...needless to say i bought the ski with damage for 800.00 and it was400 for new crank and it runs great ...but on the other had i really think i should sell it cause im worried its gona fall apart ....here a video of my ski ...

Well I am going to give teh skis a go and see, taking them out this weekend to the dam and hopefully they will be ok....

In general they look good, no major nicks and scratches, but that doesnt mean much on the motors.

So, wish me luck for the weekend.

 

[seadoosnipe]

Good luck!...

Good luck but remember, the great looks of the ski can be deceiving. You want to be sure your getting something that is worry free. You want to ride, not sit on the shore line............:cheers:
