Alarm,,, 2005 Nitro 750nx

[scott Barnhart]

I had an alarm going off last weekend out. It would come on after about a minute on full plane. It was a continuing alarm and would not shut off until I slowed down to idling speed. I checked all my oils and lower unit oil. Any other suggestions on what I can check for?? Also my water pressure guage is broke, but there is plenty of water coming out of motor...

Don't know what motor you have but it could be the water pump that is what it turned out to be on my 2009 150 optimax.

I have a 2005 merc. tracker 90hp.

Overheat most likely. When was the last time you did an impeller?

I bought my boat last summer. I will check it out.

Check your tube going to the pee hole. My 640 picked up some junk caused the alarm. I cleaned it out all was good. But if it's been a while like Toxic said,impeller wont hurt a thing to change it.
