Established in 1960, we were pioneers in the O/E replacement parts segment and have a reputation synonymous with premium quality and part reliability. We over engineer our parts to exceed and outlast O/E standards, often times engineering out any part deficiencies. We use only the best input components and every part that ships out of our warehouse has been tested prior to boxing which provides us with some of the lowest failure rates in the marine engine parts industry.
