Honda BF135 HP Outboard Engine FAQs

• Does the engine come with oil? No, Honda BF135 outboard motors do not contain engine oil when shipped from the factory; you must purchase and add oil before the first use. They do contain gear oil.
• What type of engine oil should I use? Honda recommends SAE 10W-30 engine oil, equivalent to API service classification SG, SH, SJ, or SL.
• How often should I replace the fuel filter? The fuel filter should be replaced every 2 years or 400 hours of use, whichever comes first. Regular inspection and cleaning of the fuel filter is also important.
• How should I store the outboard motor for a long period? If the motor will not be used for 30 days or more, you should drain the fuel completely to prevent the fuel from degrading and causing engine failures. It is also recommended to have it serviced by a local dealer before storage.
• Can the engine be laid on its side for transport? The engine is designed to be transported in an upright position. If laying it on its side is unavoidable, you must drain the engine oil first and follow specific instructions in the owner's manual to avoid damage.
• How do I flush the engine after use in salt water? Honda BF135 and higher horsepower outboards are equipped with a garden hose style flush port. Tilt the outboard to the down position, remove the engine cover, attach a garden hose to the flush adapter, and allow fresh water to run through the engine for at least 10 minutes.
