Question
warning buzzer

Question: I have a 2002 70hp yamaha outboard #70TLRZ. Busser is going off when I troll at lowest speed…does not go off when at idle nor at full speed, just when trolling at lowest speed…I put in a new impeller and still buzzer goes off when trolling….any suggestions??? Dave

Submitted by: dave
Answer

If you are getting plenty of water and the old impeller did not break up (and is possibly plugging water ports), change the sensor.


Question
Why is the water not pumping on my Yamaha Outboard?

Changed water pump and water is pouring out of the relief holes but not out of the "pee hole" at the top of the engine. Anything else it could be?

Submitted by: Korlin
Answer

Try checking the thermostat.
