Action Marine keeps cutters in wave-cruising order with its comprehensive boat-maintenance services. A recommended part of the summerizing process, boat tune-ups are overseen by Action Marine?s certified technicians, whose constant training keeps them up-to-date on techniques for stomping out nautical nuisances on ships from manufacturers such as Mercury, Yamaha, MerCruiser, and Johnson. A typical tune-up involves inspecting the fuel and wires, replacing overworked filters and rotors, and making sure spark plugs haven't been replaced with vintage Game Boys. Mechanics also take a deeper look at engines, preventing mean-spirited contaminants from spiking the fuel with water. Once properly tuned, boats shake off the rust accrued during a wintery off-season, smoothly navigating summer seas while providing the low harmonies in all-boat Beach Boys cover bands.
