Key Features

• Genuine Mercury MerCruiser Quicksilver OEM part
• Distributor rotor for GM V8 marine applications
• For Delco High Energy Ignition (HEI) systems

• Coated brass rotor blade designed to help resist RFI interference with onboard electronics
• Use with Quicksilver distributor cap 808483T3

Engine Compatibility
Fits marinized General Motors V8 MerCruiser engines equipped with Delco High Energy Ignition (HEI) systems. Some aftermarket listings also describe it specifically on 1993–1998 MerCruiser 5.0L, 5.7L, 7.4L, and 8.2L gasoline applications, but fitment should still be confirmed by engine serial number and installed distributor setup before ordering.

Serial Number Fitment Notice
Fitment should be confirmed by engine serial number and ignition system configuration, not by engine family alone. Match the existing rotor and confirm the engine uses the Delco HEI distributor setup and cap 808483T3 before purchase.

When This Part Needs Replacement
Replace when the rotor shows burning, carbon tracking, corrosion, cracking, looseness, or visible contact wear, or when ignition service reveals weak or inconsistent spark transfer. Rotor condition directly affects spark delivery and ignition reliability.

Installation Notes
Install only on the correct Delco HEI V8 distributor application. Confirm the replacement matches the removed rotor exactly before installation, and inspect the distributor cap at the same time. Mercury specifically identifies this rotor for use with Quicksilver cap 808483T3.

Parts Desk Insight
The key match point on 8M6001253 is the ignition family. This rotor is tied to the GM V8 Delco HEI setup, so confirming the distributor cap family first is the fastest way to avoid mixing it up with similar MerCruiser rotors for EST or 4-cylinder applications.
