I just bought an '02 gp1200 that the guy had sitting in his garage for the last 3 months. He said it ran before he put it up, but now its not. When I go to start it the warning light comes on and the buzzer goes off. He said, the guy before him put a D-plate on it with the aftermarket temp sensor. I have no idea where to go from here. Someone else told me that it could be the "raw" water impeller. Any help would be helpful. Also is the ski oil injected or gas mixed? Could it be a low oil problem?
