It’s tough as being a boat engine! Unlike its automotive cousins, a speed boat engine operates at extremely high RPM’s and under a good load while in operation plus it sits kept in storage a considerable amount of enough time. It’s kind of the worst of all possible worlds. Today’s marine engines are made and in contrast to kinds, really experience not many mechanical problems if they are properly maintained.
Water Pump Maintenance – Most marine engines are cooled by their pumping of lake or ocean water in the engine coming from a pickup within the lower unit with the outdrive or outboard engine. This water is circulated with a water pump that contains a rubber or plastic impeller or fan which pulls water through the lake and pumps it up and through the river jacket from the engine to keep things cool. As you may expect, you’ll sometimes find impurities in water or the operator (another person, I believe) that runs the reduced unit aground and the impeller covers sand, dirt or another grit. These foreign substances wear around the impeller and often lead it to shred into pieces and fail. Also, in the event the engine is stored for nearly a year, sometimes the rubber with the impeller gets brittle and cracks up. The point is, it’s just best if you proactively replace the impeller every 3-4 boating seasons. When the impeller fails if you are running and you also neglect the temperature rising, your engine can certainly and quickly overheat and self destruct.
Oil Change – Marine engines are normally not run more than 60-80 hours per year and, therefore, do not require oil changes often. Usually, this is a good option to improve the oil (and filter) once each year after the summer season. In the event the old, dirty oil is in the crankcase if the engine is stored in the off season, it may turn acid and damage the internal engine components it’s supposed to protect. Obviously, 2 stroke outboards don’t have any crankcase and for that reason no oil to change. On these applications, it certainly does pay to stabilize any fuel keeping 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 simply become clogged and might fail at the start of the season. To avoid this occurrence, it is a good plan to operate some fuel injector cleaner mixed into the last tank of fuel before the engine is defined up for storage.
Battery – If you take good care of your boat’s battery, it’s going to present you with a long period of fine service. You must take care once you accomplish a voyage in order that all electrical components are deterred and, when you have a principal battery switch, be sure it is turned off. Whenever the boat is stored for any prolonged period of time, it cables needs to be disconnected.
Lower Unit Lubrication – The bottom part of your outdrive or outboard engine is loaded with a lubricant fluid that keeps all of the moving parts properly lubricated and working efficiently. The reservoir should not contain water inside the fluid. The drive should be inspected at least annually in order that the drive is filled with fluid which no water is present. This is not at all hard and inexpensive to perform.
Electronic Control Module – Most advanced marine engines are controlled by a 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 would it be stores operational data while the engine is running. Certified marine mechanics have digital diagnostic tools that may be attached to the ECM to learn the important good the engines along with any problems.
Anodes Around the underwater part of every outdrive and outboard engine, you’ll find several little metal attachments called ‘anodes’. They are usually made of zinc and they are made to attract stray electrolysis. This takes place when stray voltage inside the electric system of the boat is transmitted through the metal areas of the boat in search of a ground. The anodes are created to be sacrificial also to absorb the stray current and gradually deteriorate. This procedure is magnified in salt water. At least once per year, you can even examine your anodes for decay and replace the ones 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 will offer you years of hassle free operation. It ought to be imperative that you one to know a professional marine technician in the area. Associated with pension transfer things, “An ounce of prevention may be worth a pound of cure”.
