2007 DF175 with 900 hours.
Prior to starting the motor with the key turned to the accessory mode (first click), I use to hear the fuel pump make a electrical wheeze sound and the sound of gurgling fuel for about 3 to 5 seconds. I'm assuming that's the fuel pump priming prior the the motor starting up. Around 775 hours, I stopped hearing that sound. Now it's completely silent when I turn the key in the accessory mode. Is this a precursor that the fuel pump needs replacement? I know the high pressure fuel pump is scheduled to be replaced around 900 hours so wondering if that's my issue or if it might be something else that is en route to fail.
Motor starts up at first crank every time. Even when boat has sat for over a month. Motor is well taken care of and all maintenance done on schedule. Engine is reaching 900 hours and still running like new. Is this something I should not worry about or is it time to replace a part to bring that fuel pump priming sound back for preventative maintenance?
