It’s hard being a boat engine! Unlike its automotive cousins, a boat engine runs at elevated RPM’s and under a good load a lot more operation plus it sits in storage lots of time. It’s sort of the worst of all possible worlds. Today’s marine engines are very well made and unlike ones, really experience hardly any mechanical problems if they are properly maintained.
Push Maintenance – Most marine engines are cooled by their pumping of lake or ocean water into the engine from your pickup inside the lower unit with the outdrive or outboard engine. This water is circulated by a push that contains a rubber or plastic impeller or fan which pulls water in the lake and pumps it down and through the river jacket with the engine to keep things cool. As you may expect, there are sometimes impurities within the water or perhaps the operator (some other person, I believe) that runs the lower unit aground and the impeller picks up sand, dirt or other grit. These foreign substances wear for the impeller and sometimes make it shred into pieces and fail. Also, when the engine is stored for a period of almost a year, sometimes the rubber of the impeller gets brittle and cracks up. In any event, it is just a good idea to proactively replace the impeller every 3-4 boating seasons. If your impeller fails while you are running and you neglect the temperature rising, your engine can certainly and quickly overheat and self destruct.
Oil Change – Marine engines are typically not run greater than 60-80 hours annually and, therefore, do not require oil changes sometimes. Usually, it is a good idea to change the oil (and filter) once each year after the season. When the old, dirty oil is within the crankcase in the event the engine is saved in the off season, it might turn acid and damage the internal engine components it is supposed to protect. Of course, 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 residing in 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 able to age and thicken during storage, the fuel injectors can certainly become clogged and may fail at the beginning of the growing season. To prevent occurrence, it’s a wise decision to own some fuel injector cleaner mixed to the last tank of fuel prior to engine is scheduled up for storage.
Battery – If you take care of your boat’s battery, it is going to present you with a few years of good service. You should be aware once you complete a voyage to make sure that all electrical components are deterred and, for those who have an important battery switch, be certain that it’s powered down. Whenever the boat is stored for virtually any prolonged time frame, battery cables should be disconnected.
Lower Unit Lubrication – The low a part of your outdrive or outboard engine is stuffed with lubrication fluid that keeps all the moving parts properly lubricated and running smoothly. The reservoir should never contain water in the fluid. The drive needs to be inspected at least annually to make sure that the drive is stuffed with fluid understanding that no water is found. That is not hard and cheap to perform.
Electronic Control Module – Most advanced marine engines are controlled by the computer call an ‘Electronic Control Module’ (ECM) which regulates the flow of fuel and air and also the timing with the ignition system. Another valuable aim of the ECM could it be stores operational data while the engine is running. Certified marine mechanics have digital diagnostic tools that may be linked to the ECM to learn the important good the engines as well as any problems.
Anodes For the underwater area of every outdrive and outboard engine, you will find more than one little metal attachments called ‘anodes’. They are generally made of zinc and therefore are meant to attract stray electrolysis. This takes place when stray voltage inside the electric system of a boat is transmitted from the metal aspects of the boat looking for a ground. The anodes are created to be sacrificial and to absorb the stray current and gradually deteriorate. This method is magnified in salt water. At least per year, you can examine your anodes for decay and replace people who have the symptoms of decayed greatly. Replacement anodes aren’t tremendously expensive and they serve to protect your boat from some serious decay of some extremely expensive metal marine parts.
If your marine engine is properly maintained, it will give you years of trouble free operation. It needs to be important to you to know a professional marine technician locally. Associated with pension transfer things, “An ounce of prevention will be worth one pound of cure”.
