2005 rxp

[spx800]

Hello, i'm just curious if there are any known issues with this machine, or things that should be addressed when looking at one.? I know the original super charger washers need to be changed, but that's about it. Any info is appreciated. What would good compression numbers be?

Thanks

How many hours are on it? If over 100 hrs, has the supercharger been fully rebuilt (they have 100 hr rebuild intervals)? '05 4TEC engines have the hollow sodium filled exhaust valves that have cracking/breaking problems (the valve head pops off, bad mojo!)... you might want to look into having the exhaust valves replaced with the upgraded solid exhaust valves. There's another thread on here you might want to look up regarding 4TEC engine reliability it's about 1 year old now I think but FULL of good information about these engines.

ps. Test ride/drive the thing before making any offer! Don't take the seller's word that it runs well.

Ok, thanks for the info; i'll make sure to read it before going any further. There are only 61 hrs on the machine and it looks really clean. replacing the exhaust valves and super charger rebuild shouldn't be too bad if that's it.

I just bought an 05 rxp last thursday & I sure wish I would've taken your advice on test driving it 1st. Took it out for the 1st time yesterday & it almost sunk. Discovered the exhaust manifold hose was completely off so water came rushing in when I attempted full speed. After flushing it all out got it started again and ran perfect 1/2 way around the lake until the check engine signal came on & it shut off. Motors turning over but not firing up any idea on what could've happened?

No ideas really. Sorry there just isn't enough information.

Is there a Mode button on your handlebar? If so, I believe you press it 5 times in a row to get the diagnostic code to show on screen, then you can Google the code for more info and/or post it here. You have to already have the check engine indicator lit though before that will work, I believe it clears itself out with every restart. Very strange that it shut down completely and didn't just go into "limp" mode though... I'm guessing the computer must think the problem is very serious in order to shut the system down completely like that.

How many hours are on this machine? Did you check the engine oil level and the coolant bottle level? When was the engine oil and filter last changed? When were the spark plugs last replaced? (4TEC engines eat spark plugs fairly fast apparently, I been bit on the butt by that myself just last Fall had me totally confused what had gone wrong was just failed plugs).

If in doubt, change everything (read how to change the oil 1st though... there are numerous posts about the best ways to change the 4TEC engine oil... or take it to a shop and have them do it).

ps. Engine oil and filter, and the spark plugs should be changed annually.... coolant system should be flushed and replaced with new coolant about every 3 years. Superchargers should be fully rebuilt every 100 hrs of operation. Again if you don't know for certain when this stuff was last done you should go ahead and do it or get it done.

Yes there is a mode button but the check engine light no longer shows. It has 93 hours, just bought last thursday, it had a fresh oil change & brand new spark plugs which was all checked before I rode it. Coolant level was good as well. I know i want to get the supercharger rebuilt very soon, its @ the shop now @ 1st it didn't turn over & then when taking off the intake metal shavings were found inside the intake & it turned over but not firing up. I will keep u posted & I really appreciate the feedback

 

[Michael211_2000]

Air intake or jetpump intake? I'm unclear what intake you are referring to.

So it's at a shop now being looked at then... hopefully they can figure it out in short order.

Sorry metal shavings were found inside the oil filter...

 

[Michael211_2000]

Ok... that doesn't sound good at all to me. :-(

Tell me about it :-/, I'll keep u posted should know more details in the next few hours, Im praying that motor doesn't need a rebuild because I haven't even had it a week yet nor did I do one lap around the lake...

 

[Rxp_C]

Ok... that doesn't sound good at all to me. :-(

- Michael

The supercharger is done!! They're going to look further into it & make sure that's all it was

Update***- I have a broken timing chain, valves need to be replaced & have some bent rods. Thankfully no damage was done to the pistons. Should be ready next week, tried getting the seller to go @ least 1/2 on damages (2k+) & he refused so I will be taking him in to small claims court. What makes him look really bad is I have proof he's owned over 20+ jet skis and owned a shop/rental place so that automatically makes him a subject matter expert in court of law. Also have print outs of the craigslist ad where it states "Ride Ready."

Forgot to mention flywheel on the supercharger is spinning by hand so that probably needs to be rebuilt unless it was from the milkshake oil I had in there.

 

[Michael211_2000]

If the supercharger air impeller "spins by hand" then it's almost certainly lost the OEM ceramic washers, they're in pieces down inside the crankcase somewhere and you HAVE to get ALL the pieces out otherwise they'll destroy the engine. Whoever is rebuilding it needs to try to locate all the pieces of those 2 washers.

Now, as to small claims court here's what the guy is going to say in court: "I've been dealing in jet ski's for X number of years I'm an expert in them and this particular watercraft was in fact 'ride ready when I sold it to him as-is with no warranty expressed or implied". You have to prove otherwise beyond a reasonable doubt, else you're going to walk away with nothing but court costs to pay.

You best at least consult with an attorney before going to court on this so you're not just wasting your time and money.

Good luck!

Yeah my mechanic has a great rep for doing great work. Not only was the exahust manifold hose loose but so was the drive shaft and the jet pump. My mechanic said you could tell stuff inside has been tampered with, which makes sense why he couldn't look me in the eye when the deal was made... too many red flags. I spoke to a lawyer, and he ran his name and based on his background & experience he said he knew he was selling me a defective ski. I'm gonna talk to another well respected lawyer as well, I'm not worried about the court fees, its a sacrifice I'm willing to take, win or loose I bet he'll think twice of doing this again to someone else. I could see if I did laps around the lake & it broke down but only 150 yards after leaving the booeys on my 1st ride is unacceptable.

 

[Michael211_2000]

Ok, good deal then.

Did you get it back running yet? What's the total for repairs?

It should up and running this week, I'll keep you posted. I'm looking @ 2-2500 haven't got the exact amount yet, he also is throwing on a new thermostat for $30.00

Finally got to test ride my ski this past Saturday & it rode like a champ. No water inside hull, no error codes, only problem we had when we 1st launched was the oil sensor 2 was left off by the mechanic which was an easy fix. I noticed I only was getting between 7650-7700 rpms max. My cousin mentioned a piggyback sensor? What's your opinion on my rpms to get them up to the 8-8100 range?

Thanks

 

[Michael211_2000]

What's your opinion on my rpms to get them up to the 8-8100 range?

You're not. Not unless you do some major mods to the engine or downshift to a lower pitched impeller. Your rpm's are just about spot-on for an OEM engine with stock impeller at WOT IMO. I believe 8100 rpm's is what the rev limiter is set to activate in fact.

I was told different & based what I've seen online others are saying about stock motors. I basically have a stage 1 kit w/o the 14/19 prop. Going out to Laughlin this weekend we'll see how it rides out there...

You're down on rpms....what intake are you running? Stock prop for an '05 rxp is a 13/18. If you're running a 14/19 on the oem intake you ain't makin the power to twist it fast enough.
