It’s hard like a boat engine! Unlike its automotive cousins, a boat engine operates at higher than normal RPM’s and under a significant load while in operation also it sits in storage a great deal of some time. It’s form of the worst of all possible worlds. Today’s marine engines are very made and unlike the earlier versions, really experience not many mechanical problems if they’re properly maintained.

Push Maintenance – Most marine engines are cooled by their pumping of lake or ocean water in the engine from a pickup from the lower unit with the outdrive or outboard engine. This water is circulated by a water pump made up of a rubber or plastic impeller or fan which pulls water through the lake and pumps it up and throughout the lake jacket from the engine to maintain things cool. As you might expect, you’ll sometimes find impurities in the water or the operator (another person, I’m certain) that runs the bottom unit aground and the impeller picks up sand, dirt and other grit. These foreign substances wear around the impeller and quite often make it shred into pieces and fail. Also, if the engine is stored for a period of almost a year, sometimes the rubber with the impeller gets brittle and cracks up. In either case, it is just a good idea to proactively switch the impeller every 3-4 boating seasons. In the event the impeller fails when you are running and you fail to spot the temperature rising, your engine can readily and quickly overheat and self destruct.

Oil Change – Marine engines are typically not run more than 60-80 hours per year and, therefore, do not require oil changes sometimes. Usually, it is just a good idea to switch the oil (and filter) once a year following the time of year. If your old, dirty oil is incorporated in the crankcase when the engine is saved in the off season, it may turn acid and damage the internal engine components it is supposed to protect. Obviously, 2 stroke outboards haven’t any crankcase and therefore no oil to improve. On these applications, it certainly does pay to stabilize any fuel remaining in the tank and 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 may even fail at the outset of the growing season. You need to occurrence, it is a good idea to operate some fuel injector cleaner mixed to the last tank of fuel before the engine is scheduled up for storage.

Battery – If you take proper care of your boat’s battery, it’ll provide you with a few years of excellent service. You should be mindful when you complete a voyage in order that all electrical components are deterred and, for those who have an important battery switch, make sure that it’s switched off. Whenever the boat is stored for virtually any prolonged period of time, battery cables needs to be disconnected.

Lower Unit Lubrication – The bottom portion of your outdrive or outboard engine is stuffed with a lubricant fluid that keeps all of the moving parts properly lubricated and running smoothly. The reservoir must not contain any water from the fluid. The drive should be inspected at the very least annually in order that the drive is full of fluid and that no water occurs. This really is not hard and inexpensive to achieve.

Electronic Control Module – Modern 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 from the ignition system. Another valuable aim of the ECM could it be stores operational data even though the engine is running. Certified marine mechanics have digital diagnostic tools which is often attached to the ECM to find out the running good reputation for the engines and also any problems.

Anodes Around the underwater part of every outdrive and outboard engine, you can find a number of little metal attachments called ‘anodes’. They’re usually manufactured from zinc and they are built to attract stray electrolysis. This occurs when stray voltage from the electric system of your boat is transmitted through the metal parts of the boat searching for a ground. The anodes are created to be sacrificial and also to absorb the stray current and gradually deteriorate. This method is magnified in salt water. At least a year, you can examine your anodes for decay and replace the ones that seem to have decayed greatly. Replacement anodes are certainly not tremendously expensive and they serve to protect your boat from some serious decay of some very expensive metal marine parts.

If a marine engine is properly maintained, it ought to give you many years of trouble free operation. It should be important to you to definitely know a certified marine technician locally. As with most things, “An ounce of prevention will probably be worth a pound of cure”.
