LF250TXR Yamahas alarms sounding

[dieselh7]

I have a pair of 250hp ad when I come off the plain or even sometimes when idling out of the channel Ive got alarms sounding (constant alarm ) if I shut the stb engine off and restart then the alarm goes away and on the port engine ifI go into neutral then the alarm will stop . Any Ideas ?

Constant alarm could be overheat or low oil pressure, if have Yamaha Tach with warning indicators then check to see what warning is activated. Probably need to have oil pressure tested and replace water pumps.

You really need to have it connected to Yamaha diagnostic system to see what the hell is going on if it is a over temp alarm or some some thing else . thats the way it is now with all computer management systems

Could be unlreated but when was the last time you replaced the impellers? I was having an issue with idle/low speed alarms and my impeller and hosung were a mess.
