Properly maintaining your outboard engine means having regular maintenance that will extend the life of the engine. At *least* once a year, owners should tune up their outboard motor. You should follow the owners manual your specific model came with before trying to tune yours. However, there are some materials every model will need.
You will need outboard oil, soft cloths, lower-unit lubricant, fresh fuel, replacement spark plugs, and waterproof marine grease. All of these materials can be bought online or at a marine store. Some of the tools that will make your tune up easier will be the owner’s manual, a screwdriver, adjustable wrench, and pliers.
