Pair of new to me 2006 RXTs

[cbisson]

I have an opportunity to buy 2 2006 RXTs with trailers for 5k from someone I know well and trust. They both have been well maintained. They were both used almost exclusively in salt water and have not been run at all in the last 2 years. They were winterized when last put away. They each have approx. 150 hours on them. The owner thinks but is not 100% sure that the ceramic SC washers have been changed. I plan to do the following;


Before starting:

Drain old fuel
change oil
pull spark plugs lube cylinders lightly and crank over with plugs still removed
start and run briefly on hose
put them in the lake for a quick wet test
pull SC to check on ceramic washers or not

Does this sound like a reasonable approach?

Do any of you guys have advice on what else I should or should not do?

I have never before owned or worked on a PWC, and the tiny bit I do know I have learned by reading here.

Thanks,

-Craig

Sounds like a good deal especially since you can trust the PO. When you pull the superchargers rebuild them so you know for certain how many hours they have on them. Look into the valve issue as well. I know the 04-05 215's had bad valves but not sure of 06.

The 2004 to 2006 engines have Sodium filled exhaust valves. They are a bad design and can break much easier than the solid core valves. The right thing to do is pull the heads and replace them.

The SC. If they are over two years old from a rebuild they need done anyways. The bearings and squirrel cages get brittle and break.

If you get past the items I listed, you will LOVE the skis.

I have the 09 RXT-X and absolutely love the machine.

Sounds like a good plan. Having the SCs rebuilt and replacing valves both seem like good ideas. Once this work is done are their other maint items such as jet pump bearing grease etc that should be done?

How many hours are these things typically good for? I know there are a lot of variables to consider but in general if a machine is well maintained and not run at WOT all the time what's a reasonable life expectation?

Thanks,

Engines can easily get into the thousands of hours. 4-tec engine is very proven.

Hmm...sorry for being the sceptic here but uhm...if he'd a shelled out the funds to have his washers swapped...he'd a remembered that bill....everybody remembers that bill.

Until those sc's passed the finger test...I wouldn't spend a dime. Then...if they did...and you were able to get 8K+ rpm outa the motors on a ride...before you bought them...I'd pull both chargers and have them rebuilt/replaced before I put them in the water again. And I'd be sure to check the ic.

How do you check the intercooler? is it a visual inspection or a pressure test etc?

Thanks for all the help guys.

Pressure test is the best method...

I'd pull the ic's and clean the screens and run some vinegar/water through the ic tubing. Because...running almost exclusively in salt...the chances of corrosion coating those ic's is very real.

How common are failed fuel injectors? The ski I'm working on has spark on all 3 cylinders but only 1 injector is firing. If I move the 1 good injector from cyl 3 to cyl 2 it fires in 2, same thing in 1, so I know the fuses, ecu, and wiring are OK.

Is it worth it to try soaking the injectors to get them freed up?

Thanks,

There is a place you can mail your injectors to and they will test and clean them. I think it runs about $20 per injector. I recently replaced my injectors with 42# aftermarket injectors and they will work but run too rich. I am going to send my OE injectors in to be cleaned and reinstall them soon. I believe that the 42# injectors that I am currently running may be costing me a little speed on the top end.

 

[cbisson]

Has anybody been able to source new Seadoo or OEM (Siemens) injectors for a more reasonable price than the 165 the dealer wants?

Thanks,

Not quite correct Joe... the early 2006 engines had the sodium filled exhaust valves, but they changed them to solid core valves sometime during the production run. My 2006 RXT has the solid core exhaust valve according to the number printed on the exhaust valve stems (I checked!). They are original, never changed.

So, the right thing to do is to take the cover off the top of the valve cover and get a good look at the number stamped into the top of one of the exhaust valves. If memory serves, it'll either be a 72 or a 75... 72 is the weaker sodium filled valve, 75 is the good solid core valve.

Replace them if they are the sodium filled valve stems! They were prone to corrosion induced cracking and then the stem head would pop off inside the cylinder while running and cause all sorts of destruction.

I agree with your post, but,,,, We have seen many late 2006 have the sodium fills valves. Most likely to using up the engine inventory that BRP had in stock before the change.

Just like the 2008 SCs aren't suppose to have Ceramic Washers. Many of the early build have them.

And I agree with your post too, Joe... just saying that they may not need replacing, but definitely need to be inspected (at least take the valve cover top off and check the numbers printed on the stems) before deciding whether to buy new ones and replace or not. That's all!

Did I remember right about the numbers stamped on them? I think 72 is bad and 75 is good but it's been a few years since I inspected mine to be sure!
