    Need info on MSX140

    I was wondering about what kind of horsepower these models have? Also how do they handle? It is better to get the 2 stroke 140 or the supercharged 150 version? Opinions needed please.

    go with the 140,great fuel mileage and if you take care of will last long time

    Both MSX 140 and MSX 150 have about 135HP, despite the model names.

    MSX 140 2-stroke is the easier engine to maintain and repair, and that is saying something.

    I have an MSX 140. Runs well, good ride characteristics in non-smooth water.

    When the turbocharged Weber four stroke engines are running well (MSX 150 and MSX 110), owners really like them. When they are not running well, they can be a bear to work on.

    the 140 is an awsome ski...had several, worked on many. very reliable ski.
    i currently have an 03 and an 04. i prefer the 03 with a 6 degree wedge in it over the 04 with a stock wedge.
    the 03 nose dives badly with the stock wedge. i also found they run better with the water pipe inlet restrictor removed.
    the 150 is a nightmare. had 4 of them, no good ones. stay away if you are not mechanically inclined. it will send you to the poor/insane house!

    That's great info. Does Polaris still make parts for them?

    Define 'better'.

    Do you retain the stock thermostat and pressure bypass to control engine temperatures?

    Yes,

    Please explain this "water pipe Inlet resrtictor". You mean the screen? Where is the pressure bypass. In the thermostat housing?

    Any Info appreciated

    Hi, I just bought a Polaris MX 140. Any info about the idle, exhaust, plate changes would be appreciated. Basically looking for a laundry list of things I should do the ski to get it running optimally.

    Thanks
