    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.
