    yes, tighten all your hose clamps. Check for a hose that is loose

    Strap it to the trailer front and rear, back it down the launch ramp until the jet pump intake is fully submerged. Run it with the seat off, and look for where the water is coming in. You can even open up the throttle like this. Just make sure the hull is well secured, and the tow vehicle brakes are set.

    If water is coming in around the drive shaft seals, you may need to remove the cover over the drive shaft to confirm.

    After about 100 hours (especially if it was used in salt water) the seals and bearing in the through-hull bearing carrier assembly should be replaced. The assembly must be rebuilt, as new through-hull MSX bearing carrier assemblies are no longer available from Polaris.

    Sealed MSX through-hull driveshaft bearing assembly PN 1350091
    How to check for leaks at the MSX through-hull bearing
    Recommended replacement/rebuild of MSX through-hull seals is every 100 hours or 3 years (especially in salt water)
    How to remove the MSX drive shaft
    How to remove and replace the MSX seals and bearing
    Polaris MSX through-hull bearing support carrier rebuild kit is PN 2858113
    Generic replacement bearing is a 6205.
    The inner seal is 25 x 52 x 10 (substituted with generic 25x52x7)
    The two outer seals are 25x35x10 (substituted with generic 25x35x7)


    There should be two siphon bilge drains in your MSX, one on down each side of the jet pump. There should be plastic elbows in each hose, mounted up high under the seat. Make sure the small breather holes in each elbow are not clogged. Make sure the hoses are not clogged or crushed, and the mesh screens on each inlet in the bottom of the hull are clear.

    Check that each bilge siphon hose is securely connected to its nipple on the base of the jet pump. When the engine is running, the jet pump creates a suction on those nipples, which then draws any water in the hull out.

    While you are checking things, look closely at the O-rings on the two hull drain plugs. Over time, the O-rings can age, crack and leak water. Replace the O-rings if necessary, and lightly lubricate the O-rings with silicone to keep them happy.

    sounds like you got water in the oil...you will probably have to drain it out and refill. however, I think more importantly you will need to find out how the water got in their to begin with.

    check for any cracks or loose seals and clamps.

    it almost sounds like the issue I had with my virage...when I got it home I found that almost all of the clamps and bolts were missing, and the ones that were there were loose!

    Have look through the other MSX 150 and MSX 110 threads.

    Milky oil means water or engine coolant has contaminated the oil. Beyond changing the oil to get the water out (which you should do promptly), you do need to investigate why the oil became contaminated.

    Normally the ski would be water tested after repair. If the water leak into the oil system is slow, it might not be noticable right away.

    You have two separate problems - correct?

    One is the large water leak into the hull when riding. Have you investigated this one yet?

    The other is the water getting into the oil.

    The two problems may not have anything to do with each other.
