Jet propelled boat motor? - jet boat motors

If you have problems with my 115 Johnson engine driving the boat. Used throughout the day for about 6 hours, then on the descent, which seem to have no power. Idle has done and will be in reverse order, but when I want to try the throttle, the plane seemed only. He behaved like a shift in the transmission of a moving car. I checked when I got home, but found nothing in the turbine. I think it means. Do you suck the engine? There was plenty of grass around. Is there something I can control, or rather I take him to a boat mechanic? Suggestions?
