Indmar Marine Relay – Ignition, Fuel Pump & Start | Part #556051

Keep your Indmar engine starting and running reliably with this genuine Indmar combination relay covering ignition, fuel pump, and starter functions. A failed relay is one of the most frustrating and commonly misdiagnosed electrical faults on a marine engine — causing no-start conditions, fuel pump failure, or ignition dropout that can leave you stranded on the water.

Compatible with: Indmar marine engines fitted to Malibu, Moomba, Supra, and Tige boats.

What does this relay do?
This single relay controls three critical electrical circuits:

Ignition — supplies switched power to the ignition system when the key is turned on. A failed ignition relay means no spark and a no-start condition.

Fuel Pump — activates the fuel pump when the ignition is switched on. A failed fuel pump relay means no fuel pressure and no start — commonly misdiagnosed as a fuel pump failure.

Start — controls the starter motor circuit. A failed start relay means the engine will not crank despite a fully charged battery.

Signs your relay needs replacing:

• Engine cranks but will not start — ignition or fuel pump relay failure
• Engine will not crank despite good battery — start relay failure
• Fuel pump not priming when ignition is switched on
• Intermittent starting — relay making intermittent contact
• Clicking sound from relay but engine will not start
• Engine cuts out suddenly underway and will not restart

Features:

• Genuine Indmar OEM relay
• Controls ignition, fuel pump, and start circuits in one unit
• Correct electrical specification for Indmar marine applications
• Built for marine vibration and moisture conditions
• Direct replacement — no modifications needed
