What This Part is Used For

This pump is part of the combined fuel and oil delivery system used on compatible Johnson and Evinrude two-stroke outboards. The assembly supplies fuel to the engine while also working with the oil-injection system to provide lubrication.

A weak, leaking, or failing pump can contribute to hard starting, poor acceleration, fuel starvation, inconsistent engine performance, or oil-delivery concerns.

The Pro Marine 8403P provides an aftermarket replacement option for engines that use one of the listed OMC / BRP pump numbers.

Common Reasons for Replacement

• Fuel leakage from the pump assembly
• Hard starting or extended cranking
• Fuel starvation at higher RPM
• Loss of engine power under load
• Old or damaged pump housing
• Replacement of an obsolete earlier 3-wire pump
• Fuel or oil delivery problems traced to the pump assembly

Why Choose the Pro Marine 8403P?

• Pro Marine aftermarket fuel and oil pump
• Replacement for a large family of OMC / BRP pump numbers
• Extensive Johnson and Evinrude application coverage
• Verified applications from 1990-2002 in the supplied fitment list
• Coverage includes many 40-300HP engine families
• Used on compatible VRO-style combined fuel and oil delivery systems
• Supports replacement of many older 3-wire pump applications
• 8403 alternate version linked above

Important Installation Information

• Verify the complete engine model number before ordering
• Match the original pump to one of the OEM numbers listed above
• Check the electrical connector and warning-system wiring
• Harness 174710 may be needed if the engine lacks "No Oil Warning" wiring
• Bracket 331122 is required on applicable 1984-1985 V6 cross-scavenged engines
• The supplied catalog excludes 2-cylinder 40HP and 50HP engines from the 3-wire pump replacement note
