I have a new 850 SP and buried it in a muddy stream that went from solid to a mud hole and had to leave overnight and pull out in the morning. I have not even had my first service as I have not reached the 50 hour break in service. Appear to run fine and started right up. Had to trailer it after popping a tire in the process. Any experts out there that could recommend what I need to do from here? Should I take it to the Polaris dealer and have the fluids flushed out? Seasoned rider with new rookie mistake. Your help is greatly appreciated.
