Valve Keepers for Marine Engines

Secure Retention of Valve Springs in Boat Motors

What is a valve keeper?

A valve keeper (also called cotter or valve lock) is a small metal piece that locks the valve spring retainer onto the valve stem. It ensures the valve stays properly seated under engine stress and high RPMs.

When should it be replaced?

Replace during valve train overhauls or if there is wear, looseness or visible cracking. A faulty keeper may cause valve drop and severe engine damage.

Marine-grade precision

DAM Marine supplies high-precision, corrosion-resistant keepers compatible with Volvo Penta, Mercruiser, Yanmar, OMC and other marine engines.
