Hey all, I'm new here. I just got back from the lake with my friends 04 Sporster and we had all sorts of trouble. This thing did fine leaving the dock and heading out but after a few minutes we hit a wake and this thing sat down in the water and wouldn't get back up. At 8000 rpm this thing will troll around at about 10 mph. We thought at first we were skipping but we isolated each cylinder and noticed a definite skip when we unpluged the coils seperatly. We then noticed a strange whining noise coming from the rear of the boat. We thoght maybe we had sucked something up in the pump but after trying to look up in the water intake we coudn't see anything. I'm just wondering what could have happened. This thing stays in the water all the time and he never has any service on it but change the oil and add gas. Is there something in the propulsion system that is apt to corrode or break from sitting in freshwater all the time? Is there some type of shear pin or coupling that could have broken or is it possible the impeller came apart? I'm just looking for some help in this one so I might be able to help him diagnose his proble. If anyone has any ideas I'm all ears. Thanks!

I would say the best thing to do is take a out the water, inspect the grate and impeller throughly. We had similar symptoms one time in our Speedster 160 and we had sucked up a baseball cap. Pulled the cap out, put the doo back in the water and we were good to go.

It is amazing the boat ran at all but Kevin is right, get the boat out of the water and fix either the impeller and wear ring or the wear ring only. Hopefully you didn't warp the housing by cavitating. That is the composite housing, it doesn't like being run in cavitation situations for long. I'd be curious to hear from you on the condition of the hull with respect to blisters as well. Please let me know about that.
