Clogged or dirty fuel filters can cause all sorts of problems, including reduced engine power and poor fuel economy. Fuel water separating filters take engine protection to another level by removing water deposits that might enter the fuel system. Sierra's fuel water separating filters are a perfect solution for a fuel filter replacement.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eSPARK PLUGS\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eInspect your spark plugs yearly and clean or replace them as needed. Carbon build up on the electrodes limit the spark plug's ability to efficiently produce a spark. This could cause you to experience reduced gas mileage, poor acceleration, hard starts, engine misfires and rough idling. Checking your plugs in the spring to ensure they are ready for boating season and can possibly help identify hidden problems within your engine. This is an important step in keeping your engine running at peak performance.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eOIL\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eOne of the most important things you can do for your boat engine is to change the oil regularly. Check the oil level in your engine every time you take the boat out for the day. If it's low, add more oil. Also, keep an eye on oil quality. Using a high quality engine oil offered on sierraparts.com you can be sure that you are giving your engine the best protection against the harsh marine environment. If the appearance of the oil turns milky in color, this could indicate that you have water intrusion into your engine and should be addressed immediately. Be sure to check your owner's manual to find out what type of oil is best for your engine.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eGEAR LUBE\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eAnother important aspect of boat engine maintenance is changing the gear lube. Your lower unit has several gears that rely on quality gear lubes to minimize friction and overheating. Over time, lower units can become susceptible to leaks and allow water to enter, and mix with the gear lube. This will greatly reduce the gear lube's ability to maintain proper lubrication and protect your gears from damage. Regular inspection can help you identify leaks early and reduce repair costs. This should be done according to the manufacturer's recommendations.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eBATTERY\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eBoat batteries are essential for starting your engine and powering accessories.

Using a high quality engine oil offered on sierraparts.com you can be sure that you are giving your engine the best protection against the harsh marine environment. If the appearance of the oil turns milky in color, this could indicate that you have water intrusion into your engine and should be addressed immediately.
