My 2002 Shockwave Step Skier was running horrible yesterday. Today i went to change the water separator/ gas filter and the top was covered in a black film. Any ideas on the cause?
I need some help. My friends 502 just had the Impellor replaced and the temperature sensor. The boat runs fine for about half an hour then goes
hot. You can let it idle for a few minute and it goes back to normal. What do you think the problem is? Any help would be appreciated.
