PCM GT-40 Distributor Cap & Rotor Kit — RP173082

The PCM RP173082 is a cap-and-rotor service kit for PCM 5.8L Ford GT-40 EFI marine engines. It replaces the two primary wear components inside the distributor, helping route coil voltage to the spark-plug wires for dependable ignition service. Confirm the GT-40 distributor configuration before ordering.

Key Features

• Complete service kit: Includes the matching distributor cap and rotor for a single ignition service.
• Verified PCM references: Cap RA108007 and rotor R103009 are identified for the RP173082 kit.
• Marine-ready construction: The cap and rotor are intended for the moisture, vibration, and corrosion demands of marine ignition service.
• Consistent ignition service: Replacing both mating wear components together helps maintain reliable spark distribution.

Replacement Guidance

• Inspect or replace the cap and rotor for hard starting, intermittent misfire, rough idle, hesitation, moisture or corrosion inside the cap, carbon tracking, burned terminals, rotor contact wear, or a cracked cap.
• Follow the engine manufacturer's scheduled tune-up guidance when establishing service timing.
• Replacing the cap and rotor together avoids pairing a new component with a badly worn mating contact.

Installation Notes

• Disconnect ignition power before servicing the distributor.
• Mark or photograph the spark-plug-wire locations before removing the existing cap so the firing order is preserved.
• Inspect the distributor interior for moisture, corrosion, and abnormal shaft movement while the cap is removed.
• Inspect the ignition wires and coil connections during the same service.
• Install the replacement cap in the same orientation as the removed GT-40 cap and follow the applicable PCM service procedure.

Technical FAQ

• Does RP173082 fit every Ford 302 or 351 marine engine? No. Confirm the engine is a PCM Ford GT-40 and verify the distributor configuration. Displacement alone is not enough.
• What does the kit include? The kit includes distributor cap RA108007 and rotor R103009.
• What is the aftermarket cross-reference? Sierra 18-29322 is a listed aftermarket cap-and-rotor cross-reference for applicable Ford distributor applications. Verify the distributor before substituting.
• Does the kit include ignition wires? No. RP173082 is the cap-and-rotor kit. The related PCM ignition-wire reference is RK120015.
• When should the cap and rotor be replaced? Follow the engine manufacturer's tune-up schedule and inspect sooner if you find misfire, moisture, corrosion, carbon tracking, cracks, or contact wear.

Parts Desk Insights

• Best use case: PCM 5.8L Ford GT-40 EFI marine engines equipped with the distributor matching cap RA108007 and rotor R103009.
• Common issue: Ordering by Ford displacement alone can result in the wrong distributor kit because PCM used different clip-down and screw-down configurations.
• Fitment check: Match the existing cap and rotor references, confirm GT-40 identification, and verify the distributor configuration before ordering.
