Sea-Doo Can-Am OEM Starter Relay 278003012 — Direct Replacement, Factory Electrical Fit

This is a genuine Can-Am OEM starter relay (part number 278003012), a factory original electrical relay designed to reliably engage the starter circuit on compatible Can-Am and related Sea-Doo electrical systems.

When an ATV, side-by-side, or personal watercraft won't crank, the starter relay is often the component that routes battery power to the starter motor. This listing is for a brand-new, factory-original Can-Am starter relay — not an aftermarket copy — superseding part number 278002347. It ships individually (sold each) and it's essential to confirm fitment against your vehicle's parts diagram or VIN before purchase.

How does this starter relay fit into my vehicle's electrical system?

The starter relay acts as a heavy-duty switch triggered by the ignition circuit to supply high current from the battery to the starter motor. Being an OEM Can-Am unit means it matches original specifications for connectors, pinout, and mounting so it integrates cleanly with factory wiring harnesses.

• Direct replacement for OEM relay form, pins, and mounting points
• Designed to carry starter current without overheating or voltage drop
• Exact connector configuration to mate with factory harnesses
• Superseded from part number 278002347 for correct identification

What are the signs you need to replace the relay?

Common indicators include no-crank conditions, intermittent starting, or a click from the relay location when attempting to start. Replacing the relay with this genuine Can-Am part restores factory electrical performance without the unknowns of aftermarket components.

• Single or repeated clicking at ignition with no starter engagement
• Intermittent starting that temporarily works after tapping the relay
• Visible heat damage, corrosion, or melted connector housing
• Failed diagnostic checks pointing to starter-circuit relay fault

How do I confirm fitment and install the replacement relay?

Always verify compatibility using your vehicle’s VIN, OEM parts diagram, or the relay part number stamped on the existing unit. Installation is typically straightforward: disconnect the battery first, unplug the factory connector, remove any securing fasteners, swap the relay, and reconnect the battery.

• Compare part number on old relay to 278003012
• Turn off power and disconnect negative battery terminal before replacement
• Plug into factory harness and secure with original fastener(s)
• Test start after installation to confirm proper operation

Who is this for: This genuine Can-Am starter relay is for owners, mechanics, and fleet managers who require an OEM-quality electrical replacement for Can-Am and compatible Sea-Doo platforms. If you value exact-fit factory parts, need a reliable starter circuit solution, or are restoring a vehicle to OEM specification, this factory-original relay delivers the correct fit and performance. Please verify your vehicle application and consult a qualified technician if you are unsure about compatibility or installation.
