Help! I am no mechanic and now am kicking myself for trying to "do the right thing". I have a 60C Yamaha on a 16' center console. The engine is just two years old. I have done the lower unit gear oil change but have not had a "annual service" before. The engine is run in Salt and brackish water. The engine has run flawlessly UNTIL after the servie was completed. I requested that the impeller be changed as part of the service and I was charged $32 for the impeller and $70 for the labor for the impeller. Here's my problem, which never happed before the service, and started immediatley after. In idle forward. That is the lowest speed going forward the overheat buzzer comes on and stays on until I give more power and increase the speed. It no longer can lowest speed move. While running at 6000rpm it runs great and no buzzer. What the heck did the dealer do or not do to my wonderful engine? Within 100-200 yards at lowest speed forward it starts the constant buzz. Help. The thermostat was not changed, the engine probably has 100 hrs on it. Thanks for your help. JKent
