Is there a high temperature alarm on a Yamaha 115?
I have a 1994 Yamaha 115 that gives high temperature alarm when I run at high speeds (4200 rpm)– when alarm sounds, engine starts running rough (as per manual) until it drops under 2000.

Why is my Yamaha apex overheating in the snow?
I am looking for some answers on our 2007 Yamaha Apex. My girl and I both purchased these machines new 2 years ago and ever since we have had problems with overheating. This occurs during groomed trails. Once we run through deep snow it goes away. Last year we had the extra cooler added to the rear of both machines.
