It’s difficult as being a boat engine! Unlike its automotive cousins, a spead boat engine is given at very high RPM’s and under a serious load when in operation also it sits in storage lots of the time. It’s kind of the worst of all possible. Today’s marine engines are made and in contrast to their predecessors, really experience not many mechanical problems should they be properly maintained.
Water Pump Maintenance – Most marine engines are cooled by their pumping of lake or ocean water in to the engine coming from a pickup within the lower unit of the outdrive or outboard engine. This water is circulated by a water pump which contains a rubber or plastic impeller or fan which pulls the lake from your lake and pumps it down and thru the river jacket from the engine to maintain things cool. As you might expect, there are sometimes impurities within the water or even the operator (another person, I know) that runs the reduced unit aground as well as the impeller picks up sand, dirt or any other grit. These foreign substances wear about the impeller and sometimes lead it to shred into pieces and fail. Also, if the engine is stored for a period of several months, sometimes the rubber from the impeller gets brittle and cracks up. The point is, it is just smart to proactively switch the impeller every 3-4 boating seasons. When the impeller fails if you are running so you fail to spot the temperature rising, your engine can easily and quickly overheat and self destruct.
Oil Change – Marine engines are generally not run greater than 60-80 hours a year and, therefore, don’t require oil changes often. Usually, this is a good plan to change the oil (and filter) once annually at the conclusion of the growing season. If your old, dirty oil is within the crankcase once the engine is stored in the off-season, it could turn acid and damage the interior engine components it is supposed to protect. Needless to say, 2 stroke outboards don’t have any crankcase and so no oil to change. On these applications, it certainly does pay to stabilize any fuel keeping the tank and also to fog the engine with fogging oil before storage.
Fuel Injectors – Most newer marine engines are fuel injected and, when fuel is allowed to age and thicken during storage, the fuel injectors can easily become clogged and could fail at the outset of the time of year. To avoid this occurrence, it is just a good option to operate some fuel injector cleaner mixed in to the last tank of fuel prior to the engine lies up for storage.
Battery – Invest the good care of your boat’s battery, it’s going to give you a long period of fine service. You ought to be mindful when you finish a voyage to ensure all electrical components are deterred and, if you have a main battery switch, ensure that it’s turned off. Whenever the boat is stored for almost any prolonged time frame, battery cables must be disconnected.
Lower Unit Lubrication – The reduced section of your outdrive or outboard engine is stuffed with lubrication fluid that keeps every one of the moving parts properly lubricated and running efficiently. The reservoir must not contain any water within the fluid. The drive must be inspected a minimum of annually to ensure that the drive is filled with fluid understanding that no water is found. This is not hard and cheap to perform.
Electronic Control Module – Most contemporary marine engines are controlled by way of a computer call an ‘Electronic Control Module’ (ECM) which regulates the flow of fuel and air along with the timing of the ignition system. Another valuable purpose of the ECM would it be stores operational data as the engine is running. Certified marine mechanics have digital diagnostic tools that may be attached to the ECM to understand the functional good the engines and also any problems.
Anodes Around the underwater area of every outdrive and outboard engine, you can find one or more little metal attachments called ‘anodes’. They are usually manufactured from zinc and are meant to attract stray electrolysis. Such a thing happens when stray voltage in the electric system of the boat is transmitted over the metal elements of the boat in search of a ground. The anodes are created to be sacrificial and also to absorb the stray current and gradually deteriorate. This procedure is magnified in salt water. One or more times annually, you can even examine your anodes for decay and replace those who have the symptoms of decayed greatly. Replacement anodes are certainly not tremendously expensive and they also will protect your boat from some serious decay of some expensive metal marine parts.
If a marine engine is properly maintained, it must present you with years of simple operation. It ought to be imperative that you one to know an experienced marine technician in your town. There’s things, “An ounce of prevention will probably be worth a pound of cure”.
