The maintenance of Your Boat’s Engine

It’s difficult like a boat engine! Unlike its automotive cousins, a boat engine is run at elevated RPM’s and under a serious load while in operation and it sits in storage a great deal of some time. It’s kind of the worst of both worlds. Today’s marine engines are made and in contrast to the earlier versions, really experience hardly any 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 the pickup in the lower unit from the outdrive or outboard engine. This water is circulated by a water pump which contains a rubber or plastic impeller or fan which pulls water in the lake and pumps it down via the lake jacket in the engine to keep things cool. As you may expect, there are sometimes impurities in the water or even the operator (another person, I’m certain) that runs the lower unit aground and the impeller covers sand, dirt and other grit. These foreign substances wear on the impeller and often allow it to shred into pieces and fail. Also, when the engine is stored for many months, sometimes the rubber of the impeller gets brittle and cracks up. In any case, it’s simply recommended that you proactively replace the impeller every 3-4 boating seasons. In the event the impeller fails if you are running and you also fail to notice the temperature rising, your engine can certainly and quickly overheat and self destruct.

Oil Change – Marine engines are generally not run a lot more than 60-80 hours annually and, therefore, not one of them oil changes often. Usually, it is just a wise decision to switch the oil (and filter) once annually at the end of the growing season. In the event the old, dirty oil is within the crankcase once the engine is saved in the off-season, it may turn acid and damage the interior engine components it’s supposed to guard. Naturally, 2 stroke outboards have no crankcase and so no oil to switch. On these applications, it certainly does pay to stabilize any fuel staying 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 permitted age and thicken during storage, the fuel injectors can simply become clogged and may even fail at the outset of the time of year. To prevent occurrence, it is a good plan to own some fuel injector cleaner mixed in the last tank of fuel ahead of the engine is scheduled up for storage.

Battery – If you take proper your boat’s battery, it’ll give you a long period of proper service. You should be mindful once you complete a voyage to ensure all electrical components are deterred and, for those who have a main battery switch, be sure it’s powered down. Whenever the boat is stored for just about any prolonged stretch of time, the car battery cables must be disconnected.

Lower Unit Lubrication – The lower a part of your outdrive or outboard engine is stuffed with lubrication fluid that keeps each of the moving parts properly lubricated and working efficiently. The reservoir should not contain any water from the fluid. The drive needs to be inspected at least annually to ensure that the drive is loaded with fluid which no water exists. That is relatively simple and cheap to complete.

Electronic Control Module – Most modern marine engines are controlled by way of a computer call an ‘Electronic Control Module’ (ECM) which regulates the flow of fuel and air and also the timing in the ignition system. Another valuable purpose of the ECM is it stores operational data even though the engine is running. Certified marine mechanics have digital diagnostic tools that may be coupled to the ECM to understand the important good the engines as well as any problems.

Anodes Around the underwater area of every outdrive and outboard engine, you will find one or more little metal attachments called ‘anodes’. They are usually made of zinc and are meant to attract stray electrolysis. This takes place when stray voltage within the electric system of a boat is transmitted through the metal aspects of the boat seeking 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. At least once annually, you can even examine your anodes for decay and replace those who have the symptoms of decayed greatly. Replacement anodes are not tremendously expensive and they also will protect your boat from some serious decay of some expensive metal marine parts.

In case a marine engine is properly maintained, it should provide you with numerous years of trouble free operation. It needs to be vital that you you to know a professional marine technician in your town. As with most things, “An ounce of prevention will be worth one pound of cure”.
