In sunny Ibiza :-)

Williams starts runs fine no smoke no warning lights but won’t go over 4500 rpm.

Was running fine 4 weeks ago on last season fuel. Filled up with over half a tank of fuel 2 days ago so fuel fresh etc

This model does not have the child speed limiter

Turbo could be jammed ? Suggestion is that also gives smoke.

Any suggestions!?

Williams coming Friday when in Palma
 
I know it doesn't help but it was just these kinds of things that put me off JetRibs 10 years ago.
I succumbed 4 years ago and bought a JetSki but that has gone now for the same reason.
IMHO, jets are just too unreliable.
 
Few calls. Williams suggested turbo stuck ( which was my feeling ).

To fix you remove the inter cooler. ( 2 Allen keys ) below that is another Allen key to remove the air box / filter.

10mm socket goes on the end of the turbo to free it.

Took 10 mins and all working again

Suggestion is to spray wd40 into the air intake side on a regular basis.

Hope this thread might help someone else in the future. We need to recruit a Willaims / Weber expert to the forum !

Had that not worked the next thing was fuel filter ( only changed 3 hours ago ) so thanks for the suggestion.
 
A follow up.

A few days later the rib was running slow.

Asked boats to take a look.

Turbo then stuck again. Second hand turbo found ( new one in Mallorca is e2700 plus Iva plus fitting )

Turbo found jammed solid with salt. Williams mentioned that sometimes this happens!

It seems to be that over the years as you decelerate at low engine lower you get a wave of water up the exhaust that splashes the turbo.

New turbo fitted all good.

I will get the old one rebuilt in the U.K. if anyone had suggestions of who to use

The lessons seem

A flush with fresh water after every use ( I just do it if left for a few weeks)

B decelerate gently and keep a bit of power on so the turbo does not get splashed

Leave Cala Dor today for es trenc and normal service can resume !
 
I used to flush with water after every use, then last few weeks every other use. Will go back to every use again! TBH only takes a few minutes longer as the hose is out to wash the williams down anyway.
 
Not very good design if that’s what happens, perhaps a call to Williams to fit an exhaust system that’s fit for purpose. That’s not a minor fault and at that cost for a turbo is pretty poor, I have never owned a Williams but was always led to believe they are the best makers of jet ribs.
 
We used to find with alloy ( steel liners ) rotax engines in Seadoos even with strict after use flushes eventually a few years later the inside of the water channels would be clogged up .
When you stripped it down it was a white gelly suspension,
Remember rotax were for ski doos and micro lights - not sea water exposed .
I realised theses days Williams buy in Webber’s , but what was the design brief of the base Webber engines ?

Was salt water in that equation?

Another side issue with “ flush “ if you send too much pressure through , thinking “ I will blast it out good n proper “
You can similarly end up with water ( albeit fresh ) ending up in inappropriate places and ——- wait for it —— big bill

So you are damned if you do and damned if you don,t

When I had Seadoos the dealer would supply fogging oil to be sprayed in the engine after use, had about 6 and never once had any issues with them.

Yep they sorted it by changing to 4 T and closed cooling , as the hp race unfolded with rivals bit like a boat .
Nevertheless there’s the HE clogging issues.
Seadoos are ok now because they purposely developed the engines for the lax owner .

Point was ( happy to repeat it ) —— what was the base Williams Webber engines originally designed for ?
Was seawater exposure in that design brief?

The engine is a Webber and used for all sorts. It will be marinised to a point but the purpose of my post was to help others not to go into a microscopic analysis of the engine install.

Salt on turbos is common if you google it as is the need for turbo washing. Salt fog is a fact if life and when the engine is low in a small boat one of those things I guess.

The rib is 2008 so this is accumulated over 10 years

I am a Williams fan. Most of the time the spares are very cheap ( tubes £1k). The turbo price is out of order as a car one k03 ( different theee numbers after so not the same ) is a few hundred euro.

Getting the old turbo rebuilt ( which could probably have been re used once salt removed but I had a new on there and there was slight bearing play ) is £250 in the U.K.
 
I have just left Palma and have a 2008 285 which is showing signs of a similar problem (unfortunately the steering cable seized half way through the holiday so could not run the tests I was hoping for). The manual suggests the issue could also be the ECU limiting output due to exhaust overheating. It could also be one of the Bosch HT coils which are known to fail and easy/cheap to replace.

Where did you find the re-con'd turbo in Mallorca. What is the model number?

Ps. If your steering shows signs of stiffening, replace the cable before it seizes which mine did (fortunately while following the mothership so i wasnt stranded). It's all ball ache to replace otherwise! :)

Cheers
 
In addition. The cables are in short supply on the island and williams have a back order of 15, so it may be worth having a spare.
 
The turbo is a k03 077

Williams diagnostics will tell you most faults but of course the system is not perfect.

Mine was down to 4000 rpm when stuck. Then down to 6500 ish when fouled

Best people to use in Mallorca are Tender works, Full diagnostics for all inboard and outboard, the offer good winter storage and specialise in William Jet tenders. They can rebuild your turbos or sell you an refurbed one.
