RXT 255 IS Error code 2221

[Brettandrew]

Hi Guys,

I have recently purchased an RXT 255 IS. I am pretty sure it is a 2010 Model. I am still only a beginner and getting used to all its functions etc.

i used it for the 4th time today and had few problems. Until this point It was all good

When I first started the engine - everything was ok. When I applied the throttle it would get up to 5 mph and then just rev-out when the throttle was applied further.

I have read through the operators manual again and I can not seem to find anything that I did wrong.

After turning it off and on several times - the system then produced a check engine message and then an error code 2221.

Is it just a simple amateur's mistake - or something more serious? Any assistance that anyone can provide is greatly appreciated.

Brett

Hi Guys,

I have further investigated and found the problem. It was a rock jammed in the propulsion unit. Photos below.

Having not seen what it looked like prior to the rock getting in there - can someone please advise how much damage this has caused?

Thanks in advance.

Doesnt look good at all. I would pull the jet pump and get a closer look.

Thanks Dennis. Looks like it is off to the local Dealer. It is a shame. I am on vacation and I was looking forward to hours of use.

I assume that the cylinder around the impeller should be smooth and not scored or scratched at all?

If it was me....I'd pull the pump then remove prop and ring. I'd also be looking at that rubber ring on the nose cone.

I'd send the prop to Impros. Or just buy another oem prop. I'd install a new "wear ring"....heh.

And at the very least...I'd never run my ski in shallow water or loan it to anyone that I wouldn't trust to do exactly as I wished.

Tack it up to a learning to a experience.

If you are in 3.5 foot of water or less, I would not recommend going much over idle speed.

These newer engines are so strong that they can easily suck rocks from as far as four foot deep under acceleration...

Hi Brett
I have been there and done exactly the same with my then new GTX Limited iS 260 at less than 10 hours.
Rock shaped like an egg got through the grate and rattled around in the impeller blades for a short period chipping them like yours.
It also stuffs the wear ring and shaft boot - but the big issue was stripped splines on the shaft - no propulsion then an overheat exhaust alarm. Ended up costing well over $A1000 with new shaft, impeller, seals, shaft boot, etc.
I agree with the other posts - these things are like super vacuum cleaners and can suck of crap from the bottom very easily.
I now never start in less than 1 metre (preferably deeper) and never go over idle until well into deeper water.
On return I shut the power off well before the depth decreases and then just drift in without power (you need to get the forward momentum right with no steering with experience).
I now spend a lot of time looking for grate sized rocks in my operating areas!
