What's up guys I'm new here and hope this is going in the right place. Anyways I was just given a 2000 Seadoo rx yesterday as a bonus from my boss at work! It's been a long time since I've been on a ski probably 4 or 5 years. Hope this forum will help me out with maintenance and maybe even some upgrades one day down the road but I'm pretty much stupid when it comes to keeping these things kept up. My ski has pretty much been freshly rebuilt top to bottom and hasn't seen the water yet! Hopefully will be next weekend!! I did hook it up to a Waterhose today to atleast hear it run and man it sounds good. Any tips/advice you guys have will be greatly appreciated as stated above that I know pretty much nothing about these things!!

Anything in particular I need to know about this ski or the 951 motor? I've read about the grey fuel lines, I will have to check and see about them. I also read the 951 in this hull was nicknamed the "water ingestor" because it is extremely easy to suck water in it. Is that only if you flip it or is that riding it as well? Like I said all tips and advice will be a great help since I'm a newb on the skis. I want to keep this thing as top notch as I can!!
 
Water will kill a 951 but that RX is a fairly stable hull.
The other big issue is the gray fuel lines. Pop the seat and see if it has them.
The other question is why was it rebuilt? If it blew up did they find the cause of the problem or just rebuild it. Typically the carbs get dirty and it runs lean and blows up. Did they rebuild the carbs?

Also when running on the hose.... Start the ski first then turn on the water, then turn off the water first then the ski off. Also don't run it too long on the hose because you will burn up the driveshaft seal.
 
I honestly have no idea why it had to be rebuilt. Like I said it was given to me as a bonus from my boss. It was a friend of his who bought it blown up and rebuilt it. Then he decided to sell it to buy a bigger motor for his pontoon boat. I know my boss had a list of over $2500 in new parts put in it. Piston, Rods, crank, seals, gaskets, etc etc. I had already read about the grey fuel lines, I will check when I have the chance. I normally work 7-8 or so and get home even later so I haven't checked yet. And I also read those directions about hooking it up to the hose, which I'm glad I did because I would have cut the water on first. How are the oil injectors on these? Should I bypass them and pre mix my gas? Also what oil would you guys recommend and what octane fuel?

Here's a few pics under the hull, from what I could see, it does have the grey tempo fuel lines. So with that being said, where should I get new lines and what size are they?
 
You're missing the rubber flaps on the air intakes. The marks on the head bolts indicate it's been removed.

The orange tint to the head indicates it's been overheated before.
 
These 951 seadoos are pretty high strung. You will get all kinds of opinions on oil but the one oil that is approved and used by most of us is the Seadoo XPS full synthetic. It is in a yellow bottle and can be had for under $45 per gallon. You have to use an API-TC full synthetic oil in these.

If it were mine and I got it as a gift I would replace the fuel lines with standard 5/16" fuel hose from the auto parts store. Replace the fuel selector and filter and pull the carbs to check the internal filters. I would also replace the oil filter and drain the oil tank and lines and refill with the new oil. You might have $150 into it when you are finished and this will ensure the new engine has the best chance of survival.

99% of these older seadoos need a new engine because the fuel system was not maintained and ran the engine lean causing it to blow up. Most people who don't know just figure the engine was old and blew up but do not address the fuel system and there goes their new engine.

The gray fuel lines are bad because the ethanol in the new fuel rots them from the inside and the slime plugs up the carbs so they have to be replaced.
 
Thanks for all the info guys on what to be looking for and what not. I will call the guy my boss got it from tomorrow and figure out what all got went through and what not. From what you all say Im willing to bet the fuel system wasn't went through at all, I will be taking it to a friend of mine who is a good two stroke mechanic and let him go through the carbs and probably even change the fuel lines since I don't have much free time atm and I'm not the greatest when it coming to taking stuff like this apart. You have all been very helpful. I just don't want to get out on the water and blow it up in a couple of hours
 
Now with or without the grey tempo fuel lines I plan on always running non ethanol gas no matter what. If the fuel lines aren't bad, what it be fine to run them with non ethanol, or just change them just to be safe?
 
Doing some digging around checking my lines and on top of my oil tank I find this.

I assume there is suppose to be a line connected to that nipple on top of the tank right? Sorry if the pic isn't the greatest
 
Found all kinds of junk in the fuel filter. Definitely from the insides of the fuel lines. Going to run to a parts store shortly and start replacing some of them
 
Where do I get one of those? Order it from Seadoo? Also is it possible to replace all these lines without have to take some of this stuff apart??
 
Find the service manual for it online. Here's parts source : osdparts.com , Good dude, will fix you up with almost anything you need. Ask questions here. We will help you out. Replace one length of fuel line at a time. Do a procedure on engine or system ask questions about it so we can make sure it is right. It is easy to toast an engine if the oil and fuel delivery is wrong. You kinda have a pig in a poke there. Don't know what the history is or who has worked on it and their skill level.
 
I will definitely ask plenty of questions. I'm dumb with this kinda of stuff. I honestly have no business trying to do this lol. I have a good mechanic at work whom I may have to replace the lines for me. I'm honestly leaning more towards the plate that blocks off the oil injectors. Just so I know it is getting the correct ratio. But idk yet. I just want to make sure I take great care of this thing, especially since it was given to me as a bonus. Now I do know it was "professionally" rebuilt. But that still doesn't mean their skill level was the greatest ya know...
 
Im young and I like to attempt this stuff on my own before sending it off and paying someone else to do. But I'd rather pay a little money to get it done vs a lot of money to have it rebuilt again because I did something wrong
 
The oil pumps rarely fail. As long as the little oil lines are replaced and the oil filter replaced and it is bled right, you good to go. Run the right oil too. Some motor cycle shops / dealers will have the right oil or can order it. It's a lot less hassle that way. In theory since the engine was rebuilt they did the carb too. In stall an inline gas filter before the carb. It will catch the gunk before it gets to the carb filter. You can go a long way if the guy you pick to help you can ride it too. Try to post more pictures of the engine area. We can spot missing parts or wrong installs.
