Champion QC12PEP Spark Plug CCH956M for Evinrude E-TEC 40/50/60 HP Outboards

The Champion QC12PEP Spark Plug (CCH956M) is a marine-grade replacement spark plug built for outboard engines that demand reliable ignition under sustained heavy load. It uses a copper core center electrode, which gives it increased conductivity and precise heat-range control compared to a standard solid electrode, helping the plug shed heat evenly and resist fouling during long runs at high RPM. Champion engineers this plug to resist overheating specifically in marine duty cycles, where engines often run at wide-open throttle for extended periods, unlike typical automotive use.

Construction emphasizes corrosion resistance, an important factor in a marine environment where moisture and salt exposure accelerate degradation of lesser plugs. The result is dependable, proven ignition performance and a longer usable service life between changes. This spark plug is sold as a single unit and is a direct fit for the Evinrude outboard applications listed below.

Frequently Asked Questions

What engines does the Champion QC12PEP spark plug (CCH956M) fit? The Champion QC12PEP spark plug fits Evinrude E-TEC 40 HP, 50 HP, and 60 HP L2 outboards, as well as Evinrude LV6 DI 250 HP V6 Ficht Fuel Inj. 3.0L and LV6 DI 6-cylinder 225 HP Ficht Fuel Inj. 3.3L engines.

What OEM part numbers does this spark plug cross-reference to? The Champion CCH956M cross-references to Bombardier part numbers 775983 and 5001866.

Is the electrode on this spark plug copper or platinum? The Champion QC12PEP uses a copper core center electrode, which gives it strong conductivity and precise heat-range control for consistent marine ignition performance.

How many spark plugs come in the package? The CCH956M ships as a single spark plug, so buyers running multi-cylinder outboards should order one per cylinder.

Is this a genuine Champion part or an aftermarket copy? This is a genuine Champion QC12PEP marine spark plug, identified by Champion as spark plug number 956M, not a generic aftermarket substitute.

How much does the Champion QC12PEP spark plug weigh? The Champion CCH956M spark plug weighs 0.15 pounds.

What thread size does the QC12PEP spark plug use? The QC12PEP uses a regular mouth thread size.

Why is this plug designed specifically for marine outboards rather than automotive engines? Marine engines like the Evinrude E-TEC and Ficht Fuel Injection models run at sustained high load more often than car engines, so the QC12PEP is built to resist overheating and fouling under that kind of continuous heavy-load operation.

Does this spark plug resist corrosion in a marine environment? Yes, the Champion QC12PEP is built with corrosion resistance suited to the salt and moisture exposure common in marine use.

Will the CCH956M work in a Bombardier-branded outboard? Yes, since it cross-references to Bombardier OEM numbers 775983 and 5001866, the Champion CCH956M is a correct replacement for those Bombardier applications.
