Somewhat like vanes striking the inside of a housing. Turns out it's the water cooled electric fuel pump. I assume these should be near silent. Anything to do besides new fuel pump?   gl115 Member Username: gl115 Post Number: 32 Registered: 11-2009 Posted on Sunday, November 15, 2009 - 07:33 am:    never worked on one and not a boat mechanic, hope this helps a little. http://www.marinepartsexpress.com/Merc_Schematics/7.4LX%20BRAVO%20MPI%20GEN%20VI %20GM%20454%20V-8%201996-1997/0F802000_0K999999/FUEL%20PUMP-FUEL%20COOLER-FUEL%2 0COOLED%20SYSTEM-SN-OK14735.pdf   makomark Senior Member Username: makomark Post Number: 1890 Registered: 09-2008 Posted on Sunday, November 15, 2009 - 08:18 pm:    New pump time - look at the bright side; its a lot cheaper than selling the boat.
