You should be able to rely on your boat's engine in every situation. With Liqui Moly's certified quality oils, fuel additives, and maintenance products, your engine receives precisely the care it needs. The cooling water pump impeller, oil and fuel filters, air filter, spark plugs, and sacrificial anodes must be replaced regularly to ensure reliable operation. And should something on the engine ever break down, Herman Gotthardt GmbH offers new gearboxes, propellers, and bow thrusters from leading manufacturers such as Evinrude, Johnson, Honda, Mercury & Mariner, Volvo, and Yanmar.
