It’s tough being a boat engine! Unlike its automotive cousins, a boat engine operates at very high RPM’s and under a good load when in operation and yes it sits kept in storage lots of time. It’s form of the worst of both worlds. Today’s marine engines are made and unlike kinds, really experience few mechanical problems if they’re properly maintained.
Push 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 with the outdrive or outboard engine. This water is circulated by the water pump that contains a rubber or plastic impeller or fan which pulls water from the lake and pumps it and thru the lake jacket of the engine to help keep things cool. You may expect, there are sometimes impurities in the water or even the operator (someone else, I’m certain) that runs the reduced unit aground and also the impeller sees sand, dirt or any other grit. These foreign substances wear on the impeller and frequently cause it to shred into pieces and fail. Also, if the engine is stored for nearly a year, sometimes the rubber from the impeller gets brittle and cracks up. The point is, it’s simply best if you proactively replace the impeller every 3-4 boating seasons. If your impeller fails while you are running so you neglect the temperature rising, your engine can easily and quickly overheat and self destruct.
Oil Change – Marine engines are generally not run more than 60-80 hours a year and, therefore, do not require oil changes often. Usually, it is just a good plan to change the oil (and filter) once a year at the conclusion of the growing season. If the old, dirty oil is within the crankcase when the engine is held in the off season, it might turn acid and damage the interior engine components it’s supposed to protect. Needless to say, 2 stroke outboards don’t have any crankcase and so no oil to alter. On these applications, it certainly does pay to stabilize any fuel residing 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 to age and thicken during storage, the fuel injectors can readily become clogged and may even fail at the outset of the growing season. You need to occurrence, it is just a good option to perform some fuel injector cleaner mixed in the last tank of fuel prior to engine is scheduled up for storage.
Battery – With good care of your boat’s battery, it is going to provide you with a long period of proper service. You should be aware once you finish a voyage to make sure that all electrical components are deterred and, if you have a primary battery switch, be certain that it can be turned off. Whenever the boat is stored for any prolonged time frame, battery cables must be disconnected.
Lower Unit Lubrication – The low portion of your outdrive or outboard engine is full of a lubricant fluid that keeps all 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 the very least annually to make sure that the drive is loaded with fluid knowning that no water is found. This is relatively simple and cheap to achieve.
Electronic Control Module – Most contemporary marine engines are controlled with a computer call an ‘Electronic Control Module’ (ECM) which regulates the flow of fuel and air as well as the timing with the ignition system. Another valuable aim of the ECM is it stores operational data whilst the engine is running. Certified marine mechanics have digital diagnostic tools that may be linked to the ECM to understand the functional history of the engines in addition to any problems.
Anodes Around the underwater portion of every outdrive and outboard engine, you can find a number of little metal attachments called ‘anodes’. They are usually manufactured from zinc and they are meant to attract stray electrolysis. Such a thing happens when stray voltage within the electric system of an boat is transmitted over the metal aspects of the boat in search of a ground. The anodes can be sacrificial also to absorb the stray current and gradually deteriorate. This procedure is magnified in brine. At least one time 12 months, you can even examine your anodes for decay and replace those who have decayed greatly. Replacement anodes usually are not tremendously expensive and they are designed to protect your boat from some serious decay of some extremely expensive metal marine parts.
If a marine engine is properly maintained, it should offer you many years of simple operation. It ought to be crucial that you you to definitely know a qualified marine technician locally. There’s things, “An ounce of prevention will probably be worth one pound of cure”.
