    Wildbeest, are you the first owner?
    How many hours on the ski?
    Has there been a tune done to the ECU?

    First make sure that thermostat is not stuck open, take the stat out and see if it is in the open position., it should be closed position. If it is stuck open replace with new, if okay time to pressure test head and look for leaks using compressed air and checking for cracks near the head bolts. On the exhaust side is most common.

    When you do find what is wrong, then change the oil. Don't leave the oil in the engine with water and oil mixture, then refill with fresh oil. Then pull the head, you don't want things rusting while you are waiting on a head. Because you ride in the ocean, the mixture of salt water with the oil will do a lot of damage in a short time if you don't change the oil.

    I'm the second owner, and bought it in August of last year from the local dealer with 110 hours, and it's got 155 hours on it now. Previous owner used it primarily in salt water, and so do I.

    I understand that it is totally stock. I've added a second battery, a 1100 GPH bilge pump and some electrical mods for fishing, but no mechanical mods.

    Dealer convinced me to buy a YES warranty, which I kind of felt was an $800 rip off on a $7000 ski at the time, but am glad I got now. Dealer replaced the supercharger clutch in December under warranty, and the first signs of water in the oil were after my first ride after that replacement.

    I wanted to check everything I could before taking it to the dealer because based on my last experience, it's a guaranteed month in the shop when I take it in for warranty work.

    Thermostat is closed, and it opens if pull the metal insert, but I actually can't get the thermostat out. I tried a little prying with a screwdriver, but I didn't get aggressive for fear of breaking it. There was some corrosion on the housing around it, and the aluminum/corrosion byproduct around it flaked off if I tried to pry against it.

    Well if you have a warranty with the ski and you are not going to do the repairs yourself, still do the oil change. You don't know how long the ski will sit till the dealer looks at it your ski. You don't want to do any damage to the engine on your part. Just looking out for you.

    Take Care

    @wildebeest . . . any update?

    The Dealer told me that there is water present, but running it on the hose, no more water was added that they could see. They told me to change the oil and keep riding it until there was more water. The water present could still be condensate. I told them I'd give them a call when it blows up.

    I changed the oil and filter. The oil that came out had about a 1/4 a cup of water for 3.5 quarts of oil after I let it all separate.

    I rode it and put about 4 hours on it last weekend, checking the oil periodically. The valve cover looked the same as my previous pictures with milky residue. A small tinge of milky oil shows up on the dipstick. Click image for larger version.

    The dipstick was clean after it set for a week so there's not so much water that it reaches the dipstick after separating.
    I assumed it could be some of the water I didn't get out when changing the oil. I'm taking it for another ride this weekend, and I'll let you know if the water burns off. I'm surprised it hasn't already if it's really just condensate. If it doesn't, I'll assume I've got a leak somewhere.

    I know dealers are going to take a long time with this type of issue. A friend's ski has been at the local dealer since feb dealing with the same water in oil issue...finally got a new engine approved and waiting for parts. It's a cracked head, tho the dealer hasn't come out and said so.

    if you are so inclined, you could clean off the head and apply some dye to the areas around the head bolts, and maybe you'll see a crack like the attached photo. then maybe they can quickly get a new head/engine approved for you.



    Your best bet is to run the ski in the water, get the oil nice and milky, and then just drop it off and tell them to fix it. but you've got to stay on them otherwise it's going to sit there for months and months.

    good luck!

    btw, how were they able to put a YES warranty on a 8 year old ski? how much extra warranty did you get?

    Surprisingly good news. I ran the ski all day yesterday fishing and trolling. Put 6 hours on the ski and about 50-60 miles and ran through nearly an entire tank of gas, and I now have no further sign of water in the oil at all. Apparently, you can have over 1/4 of cup of water (probably closer to 1/2 cup since I didn't get it all out changing the oil) from condensate in your oil... I'll continue to keep an eye on it, but I think I overreacted on this one.

    For the YES warranty, I bought the ski used in 2019 from this dealership, and they offered a 2 year YES warranty to me. They did tell me it was the last year they would offer the warranty. But the warranty is good until August 2021, so for most of 2021, it'll be a 9 year old ski with a YES warranty.
