What is an outboard motor?
An outboard motor is a self-contained propulsion system for boats. Unlike inboard motors, outboard motors can be removed and stored.
How often should you clean the outboard?
You should clean your outboard with every use, regardless if you are boating in freshwater or saltwater.
How often should you get your engine serviced?
You should have a marine engine professional evaluate the health of your outboard once a year. Preferably before the start of the season.
What type of anti-corrosive should you get? How often should you use it?
Each time you use your motor it needs to be cleaned. We recommend STA-BIL Rust Stopper or WD-40. An anti-corrosive will help repel unwanted moisture.
What type of fuel should you use?
Follow the manufacturer’s recommendation. Your fuel-type will depend on your outboard and its size. All outboards may benefit from use of an additive, like STA-BIL 360 Marine, to help prevent engine corrosion.
