The recommended oil type for the Suzuki DF115A 2019 outboard engine is SAE 10W-40, NMMA FC-W certified 4-stroke engine oil.
It is recommended to change the oil every 100 hours of operation or at least once a year, whichever comes first.

The correct spark plug gap for the Suzuki DF115A 2019 is 0.031 to 0.035 inches (0.8 to 0.9 mm).
Regular maintenance includes checking the oil level, inspecting the propeller for damage, flushing the engine with fresh water after saltwater use, and inspecting the fuel system for leaks.
Turn off the engine immediately, check for obstructions in the water intake, verify the cooling water flow, and inspect the thermostat and water pump impeller for damage.

Drain the fuel or add a fuel stabilizer, change the oil and filter, flush the engine with antifreeze, and store the engine in a dry place.
To reset the maintenance reminder, turn the ignition switch to the ON position, press the mode button until the maintenance screen appears, and hold the set button until the reminder resets.
