Problems with your Mercury or Mariner Outboard DFI OPTIMAX


The OPTIMAX is the most MIS-DIAGNOSED Outboard Engine.
Symptoms caused by leaking REGULATOR DIAPHRAGMS point to:

Bad Injectors
Bad Fuel Pumps
Leaking VST
Air in Fuel Lines
Bad Gas
Bad TPS

New rubber DIAPHRAGMS from OptiMaxFuelRailRepair.com will cure and correct these symptoms.  Don't Pay for NEW FUEL RAILS at OEM Prices!

The two main factors of diaphram failure are because of today's fuel content. The second reason is low engine use with long periods of sitting.
