My 95 mariner 150 started the alarm last sping and found out the gear in the motor that drives the pump was bad. It was going to be pretty expensive to replace so i had it disconnected and just mix my own gas now. The main thing is if you want to test it agin I would be sure to mix oil in your gas so you don't do any or more damage to your motor. If the pump is a problem I think the alarm should still go off.
