I have a 1996 Seadoo Jet Ski. I had it worked on last fall and was returned to me just in time to winterize. SO when I put the battery in and started this spring I saw a flashing "Low Fuel" and the red light on indicating low fuel. Saw no fuel bars. So immediately put in fuel BUT did not take as much as I would have thought if was empty. After filling up still flashing and red light. Was very dim also. Then I noticed a dark spot the size of a dime maybe in the middle. This was not what I had it worked on for. Actually they put in a new module because was bogging down at higher speeds. What is wrong and did the mechanic probably do something and screw it up?
