These outbourds utilize an on-engine fuel/water separating filter assembly incorporating a water-in-fuel warning swtich. This wrench is needed to minimize the risk of damage to the on-engine filter cup caused by the use of improper tools for the application. Can be used for general maintenance, and kept on-board for proper resolution to a water-in-fuel warning while underway. Vendor part number YB-ACC04. See your authorized Yamaha Marine Dealer for availability, ordering, and actual retail pricing.
