Marine Synthetics for what moves you!


Looking to upgrade to a synthetic for your Merc Stern Drive or the power plant that sits in front of it? If your engine is old enough to have a flat tappet cam you should strongly consider NOT using oil from your local parts shelf. Make sure you are running an oil that will support the cam to lifter interface. Modern "car" oils do not contain the proper additives to keep your cam alive.
