It’s difficult as a boat engine! Unlike its automotive cousins, a speed boat engine is given at higher than normal RPM’s and under quite a load a lot more operation also it sits in storage a great deal of enough time. It’s sort of the worst of all possible worlds. Today’s marine engines are made and unlike kinds, really experience hardly any mechanical problems if they’re properly maintained.
Water Pump Maintenance – Most marine engines are cooled by their pumping of lake or ocean water in to the engine from the pickup within the lower unit with the outdrive or outboard engine. This water is circulated by way of a water pump which has a rubber or plastic impeller or fan which pulls the water through the lake and pumps it and thru the lake jacket from the engine to keep things cool. As you might expect, you’ll sometimes find impurities within the water or even the operator (another person, I know) that runs the bottom unit aground and also the impeller covers sand, dirt or any other grit. These foreign substances wear around the impeller and quite often cause it to shred into pieces and fail. Also, when the engine is stored for nearly a year, sometimes the rubber of the impeller gets brittle and cracks up. In either case, it’s just best if you proactively replace the impeller every 3-4 boating seasons. If your impeller fails if you are running so you fail to notice the temperature rising, your engine can easily and quickly overheat and self destruct.
Oil Change – Marine engines are normally not run over 60-80 hours annually and, therefore, do not require oil changes very frequently. Usually, it’s a good option to improve the oil (and filter) once annually after the growing season. In the event the old, dirty oil is within the crankcase when the engine is saved in the off-season, it could turn acid and damage the inner engine components it is supposed to shield. Needless to say, 2 stroke outboards don’t have any crankcase and for that reason no oil to improve. 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 permitted age and thicken during storage, the fuel injectors can easily become clogged and might fail at the beginning of the growing season. To prevent occurrence, this is a wise decision to perform some fuel injector cleaner mixed to the last tank of fuel prior to the engine is defined up for storage.
Battery – Invest the care of your boat’s battery, it will provide you with a long period of good service. You must be aware if you complete a voyage in order that all electrical components are switched off and, for those who have a principal battery switch, be sure it is switched off. Whenever the boat is stored for virtually any prolonged stretch of time, it cables ought to be disconnected.
Lower Unit Lubrication – The reduced section of your outdrive or outboard engine is stuffed with lubrication fluid that keeps each of the moving parts properly lubricated and running efficiently. The reservoir shouldn’t contain water from the fluid. The drive should be inspected no less than annually to ensure that the drive is stuffed with fluid understanding that no water is present. This is easy and inexpensive to complete.
Electronic Control Module – Most contemporary marine engines are controlled by the computer call an ‘Electronic Control Module’ (ECM) which regulates the flow of fuel and air plus the timing from the ignition system. Another valuable function of the ECM is it stores operational data while the engine is running. Certified marine mechanics have digital diagnostic tools that may be coupled to the ECM to understand the important good reputation for the engines in addition to any problems.
Anodes About the underwater part of every outdrive and outboard engine, you’ll find one or more little metal attachments called ‘anodes’. They are generally manufactured from zinc and they are designed to attract stray electrolysis. This takes place when stray voltage within the electric system of the boat is transmitted over the metal aspects of the boat in search of a ground. The anodes can now be sacrificial and absorb the stray current and gradually deteriorate. This procedure is magnified in brine. At least one time annually, you can examine your anodes for decay and replace those that appear to have decayed greatly. Replacement anodes are not tremendously expensive and they also actually protect your boat from some serious decay of some very expensive metal marine parts.
If the marine engine is correctly maintained, it must provide you with years of simple operation. It ought to be important to one to know a qualified marine technician in your town. There’s things, “An ounce of prevention will be worth one pound of cure”.
