low preasure fuel pumps

[crojas]

Hello,
What are the symptoms for bad low pressure fuel pumps on a 2000 225 HP 2 stroke? Also what are those for a bad or dirty O2 sensor?

Fuel pump can cause a fuel stavation or fuel too rich condition if bad. The O2 sensor can make the engine run bad at low or high speed, may even loose rpm's.

if lp pump, look for unspent gas out of prop/in water.after 7 yrs of service, the pumps should be changed out...hopefully the 02 sensor has been cleaned a few times since also.
