2006 90HP 2 Stk Alarm

[therealdeal]

I have an alarm sounding after I have been running for appr 10 min. I have read some articles about the cooling system. It seems my problem matches those symptoms and I want to replace the impeller,thermostat and the sensor. My problem is I do not have a service manual to give me the proper procedure to do each of the tasks listed. Does anyone have a service manual in PDF for for my particular motor? Or any good suggestions on how to proceed?

Google: Yamaha Maintenance Tips Andy, for instructions with photos for water pump and other procedures. The thermostat and pressure control valve are very easy, 4 bolts on top/back of cylinder head. Good Luck!
