Detroit Series 60 825HP Marine Camshaft | 12.7L / 14L | Replaces 23533558

Looking to wake up your Detroit Series 60?

The Aftermarket Detroit Series 60 825HP Marine Camshaft is designed as a replacement for the original Detroit Diesel 23533558 Marine Camshaft, used in high-horsepower 825HP Series 60 marine applications.

The 825HP Marine Cam has become a popular performance upgrade for on-road Detroit builds, offering a high-output marine cam profile for engines moving beyond the factory truck configuration.

This is a brand-new aftermarket replacement, not a reconditioned OEM camshaft or a custom performance regrind. It is designed to provide an alternative to the increasingly difficult-to-source original Detroit marine camshaft.

For performance-oriented 12.7L and 14L builds, this camshaft offers access to the popular 825HP marine-style profile without the cost and availability challenges of sourcing an original OEM unit.

Brand New. No Core Required.

Why Run the 825HP Marine Cam?

The original Detroit 23533558 camshaft was designed for high-output Series 60 marine applications operating under sustained load.

For on-road performance builds, the 825HP Marine Cam profile has become a popular upgrade for trucks running:

• Larger turbochargers

• S400 and other performance turbo setups

• Upgraded injectors

• Higher-horsepower ECM tuning

• Performance-oriented street and competition builds

Our aftermarket replacement provides an alternative to the original Detroit camshaft for builders looking to incorporate this popular marine cam configuration into their engine build.

Why It's Popular in Performance Series 60 Builds

The 825HP Marine Cam has earned a following among Series 60 performance builders because of its use in high-output marine engines and its popularity in modified on-road applications.

It is especially popular for builds combining:

• Larger-frame turbochargers

• Increased fueling

• Performance injectors

• Custom ECM tuning

• High-horsepower 12.7L and 14L combinations

When matched with the proper turbocharger, fueling, and tuning, an 825HP marine-style camshaft can be part of a serious Series 60 performance combination.

As with any performance engine component, results depend on the overall engine configuration, supporting modifications, and calibration.
