      Mercury Outboard Fuel Filters

      While we all know how important gas is for your car the same rings true for your boat, however, your boat fuel needs special care to keep the engine running at optimal performance. With-in two weeks or so gasoline left sitting starts to go bad. Components of the gas begin to oxidize and form a gum-like substance. This substance can settle in other engine parts such as the fuel lines and begin to build up and impact the performance of your engine. Maintaining and replacing your fuel filter is a key component to keeping your engine parts clean from gasoline sludge.

      Mercury outboard fuel filters should be checked often but replaced every 200-300 hours but can be done more often if needed. Fuel filters can become clogged quickly so having a spare on board is always a good idea. These inexpensive parts can save you hundreds to thousands in costly repairs if they are maintained properly. Not sure which mercury outboard fuel filter you need, check out our fuel filter selection guide to help you find what you need.
