    MSX 140 03 Project

    Hello all fellow Polaris folk,
    Today I bought my first ski every and yes an MSX 140 03 model with my good long time friend URUGOL and some of you may already know him to have worked on many projects before from Polaris to Yamaha skis. Anyway, back to the ski! It was a very cheap ski sine when URUGOL and I had a look at it it looks like it has been riden in fresh water mainly or serviced and clean well due to very little signs of corrosion. After attempting to get the ski to start we noticed there was some sort of issue either with the starter, top end issue or possibly the crank! The plugs look good and once we took e air filter off and looked into the motor to see the oil BAMB! There it was hydrolocedk! Seeing this was a great price and the Polaris MSX 140 is such a beautiful thing I wanted my first ski to make me work a little so I took her on board.

    I am in Sydney Australia and seeing since it is dark tomorrow during the day I will take some pictures and load them on this thread to give some visuals.

    In the meanwhile I would like any assistance I could get on how to go about clearing out an engine which has been hydrolocked.

    Thanks and it is a pleasure to be part of the green hulk!

    Welcome !!!!!
    I would pull the plugs and see if it cranks over if it does spray some fogging oil down into the cylinders and then pull the flame arrestor and spray fogging oil down the throttle boddies to oil it up and then see if it will run from there but i bet it will need to be rebuilt if that water has been in there awhile .

    Welcome to the Hulk Martin!

    Make sure you put up some pictures as you go, it really helps the guys see what you see instead of speculating. Just to give the guys a run down, I take some responsibility for pushing this deal but this ski is as immaculate as they come. Not a sign of salt water entry anywhere. There is no water in the combustion chambers as such, the water has been there for a while I managed to turn the the engine by hand about an inch or 2 either way then it stays locked, I think at worst the crank is prob twisted. Interestingly when we removed air intake you can see the water level in the engine on the cen/pto cyls only. We will prob be seeking a good 1200 crank at worst.

    I would have bought this for myself, but I already have 2 projects in the garage if I turned up with a 3rd I would be looking for a place to sleep right now

    Where's those pics!!!!

    All I finally have some start up porn to get you going. Starting from last night when URUGOL and I drove it home up till I rempved the first injector and first cylinder think it is called the PTL? You will see that the piston dome has water droplets and after sampling the water from the air intake it is definatley freash water which is a good sign! With the photos of the open piston does anyone see signs of a possible bent con rod?

    Tomorrow I will plan on taking out the rest of the injectros and cylinder heads, plus the exhust outlets to start puming out the water in the aim to check out the crank to see what damage I will be expecting!









































    Cheers,

    Nice, your just like beerdart now but without the off it's nut powerplant

    Pull that PTO jug off you need to get to that water in the case and siphon it out take a pic lets have a look. The head dome looks new, prob had a good wash from the water

    I noticed there is no sign of the ski being flipped. I wonder if this thing got full of water from being towed over a considerable distance/speed The seat is quite dry I don't think she been flipped......

    Looking at that cylinder jug I stand by my assessment that this thing has unliikely ever been ridden in the salty stuff.

    Exclamation Update on the MSX 140

    All,
    A quick update on where I am at with the MSX 140 ski. I have removed the all injectors and cylinder heads, exhaust system and exhaust manifold. I have noticed that the exhaust pipe was almost completely full of fresh water! Almost as much water as what the water silencer had inside. So far I have not seen any signs of corrosion, knock on wood!!!

    Tonight once I remove the cylinders off I will upload some pictures to provide visuals for everyone. Once I get there I will have a better understanding of the kind of damage the con. rods, pistons and cylider walls have. Also a bit of an insight into the state of the crank.
