    Starting issue 2003 msx 140 ho

    Hello,

    This is the first time for me here, and this place is full of useful information. I was looking to find out if this issue someone has had and I was not able to get my answer. I am looking to buy me a Project jet ski this is a 2003 Polaris MSX 140 HO good condition overall compression, spark and fuel pressure is there, problem is when you hit start button I only hear starter spin without turning the engine at all. Did anybody have this issue and what this might be before I get this? or should I get this ski at all guy is asking $1200 for trailer/ski.

    Probably a damaged starter bendix or broken gear teeth on the flywheel. If thats all that is wrong I would buy it for 1200.

    Thank you, I guess the best way to check is to take it apart, do I have to get the engine out to replace those parts if that ends up being the case?

    It would be easier to work on with the engine out, but its probably possible to do it with the engine in the hull yet.

    If the battery is really weak then it is possible for the Bendix to not engage?

    How did you check these things if it will not crank and start?

    Have you seen this engine actually start, idle, and rev up?
