Regular maintenance is important for any outboard and only you can make sure it happens. A tune up should be done every year or every 100 hrs, whichever comes first, at a minimum. The oil should be changed every 50 hrs or 3 months to extend its life and ensure its reliability.
Always use fresh fuel within two months, without fuel conditioner, about 6 months with conditioner, to prevent phase separation. You should run the engine once a month for approximately 30 minutes.

After every outing, flush out the engine for 15 minutes. This applies to both fresh water and salt water. While flushing, check the water pump to make sure it has good water flow and that the water stream is not hot.
After flushing, disconnect the fuel line and allow the engine to burn all the fuel in the carburetor. It’s important to always use fresh fuel. At the end of the season or after sitting for 60 days, drain your tanks and take the fuel to the proper recycling authority.
After running the engine out of fuel, turn off the key and battery switch, if you have one. Wipe everything down and spray all the moving parts with an anti-corrosive lubricant such as WD 40. We advise you rinse down and lubricate your trailer fittings as well.
