Seadoo RXDI Rave Valves - Is this normal?

[Phil-UK]

Hi all,

My first post on this forum :thumbsup:

Just pulled the rave valves on my 2001 Seadoo RXDI (130 hours) to give them a clean up and although I was expecting some carbon build up (there was lots) I was surprised to find them dripping with thick black oil (see pics), is this normal? Not sure if relevant but there also seems to be a few drops of water in the oil.

Also found a part of a o-ring in the sludge so I'm guessing a couple of rebuild kits required? Anyone know if these can be sourced here in the UK?

How do I know if the rave valves were even operational? I was hitting about 50mph flat out at 6500rpm with no real boost in power anywhere in the rpm range.

All comments appreciated.

Thanks

What oil are you using? It looks like the buildup might be from not using Seadoo Synthetic oil.

Only just bought the ski but the previous owner (for last 10 years) used the proper Seadoo DI oil and had receipts to prove

a 951 should run about 7,000 RPM wide open if everything is brand new / in spec. Clean these up and hit them with some wd-40 or something that will cut the grease, but not remove the lubrication aspect. you can clean the raves with brake cleaner, but then I hit them with some WD before reinstaling.

Thanks for the reply, is that much black oil build up on the raves normal?

I clean mine every fall, but I've seen some pretty bad ones on other peoples skis.
