hi, acquired a '96 polaris 750 for free..hull is in good shape and engine turns over but after pulling the plugs i noticed one of the pistons had a small hole in it, other than that, it may actually run..i'm guessing this project would be called an engine rebuild?(not sure whats involved) roughly, how much am i looking at to have this rebuilt? i know nothing about pwc and dont have the time anyway. thanks in advance
