Hello, My 1994 Yamaha Waverunner 3 will idle but wont take throttle. It overheated when I pulled sand into exhoust. I cleaned exhaust out and took it out and it ran fine for 2 hours, now it will not take throttle. I have changed fuel lines,filter, rebuilt carb, rechecked rebuild, and still no change. Question: can the thermo switch have gone bad from overheat and be sending bad reading causing limiter to kick in. If so how can I check thermo unit to see if that is problem, It is an expensive part to change without being sure. Thanks, Don

I will answer my own question. It was the thermo sensor. It was a $120.00 part so I did not want to cut it away and waste $120.00 but i did cut and that took care of problem. The downside it does not have the safty cutoff until I decide to spend the $120.00 but I have a temp gauge on it so I am good.
