Managing Your Boat’s Motor

It’s hard as being a boat engine! Unlike its automotive cousins, a boat engine is run at elevated RPM’s and under quite a load a lot more operation plus it sits kept in storage a whole lot of enough time. It’s form of the worst of all possible worlds. Today’s marine engines are very well made and in contrast to ones, really experience few mechanical problems should they be properly maintained.

Push Maintenance – Most marine engines are cooled by their pumping of lake or ocean water in the engine from the pickup inside the lower unit from the outdrive or outboard engine. This water is circulated by way of a push made up of a rubber or plastic impeller or fan which pulls water through the lake and pumps it up and through the lake jacket of the engine to help keep things cool. As you might expect, you’ll sometimes find impurities in the water or perhaps the operator (somebody else, I’m certain) that runs the low unit aground along with the impeller sees sand, dirt and other grit. These foreign substances wear on the impeller and quite often cause it to shred into pieces and fail. Also, if your engine is stored for a period of many months, sometimes the rubber of the impeller gets brittle and cracks up. The point is, it’s simply a good idea to proactively replace the impeller every 3-4 boating seasons. If the impeller fails if you are running so you neglect the temperature rising, your engine can simply and quickly overheat and self destruct.

Oil Change – Marine engines are normally not run greater than 60-80 hours each year and, therefore, don’t require oil changes often. Usually, it is a good option to alter the oil (and filter) once per year at the end of the growing season. If the old, dirty oil is within the crankcase if the engine is saved in the off season, it can turn acid and damage the internal engine components it’s supposed to shield. Naturally, 2 stroke outboards have no crankcase and thus no oil to improve. On these applications, it certainly does pay to stabilize any fuel remaining in the tank also 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 easily become clogged and may fail at the outset of the season. You need to occurrence, this is a good idea to own some fuel injector cleaner mixed to the last tank of fuel ahead of the engine is put up for storage.

Battery – With care of your boat’s battery, it’s going to present you with several years of proper service. You should be mindful if you finish a voyage to make sure that all electrical components are switched off and, if you have a primary battery switch, ensure that it is turned off. Whenever the boat is stored for virtually any prolonged time frame, the battery cables ought to be disconnected.

Lower Unit Lubrication – The bottom portion of your outdrive or outboard engine is full of lubrication fluid that keeps all the moving parts properly lubricated and running smoothly. The reservoir should never contain any water in the fluid. The drive should be inspected at least annually to ensure the drive is stuffed with fluid which no water occurs. This is easy and low-cost to complete.

Electronic Control Module – Modern marine engines are controlled by the computer call an ‘Electronic Control Module’ (ECM) which regulates the flow of fuel and air as well as the timing from the ignition system. Another valuable purpose of the ECM would it be stores operational data even though the engine is running. Certified marine mechanics have digital diagnostic tools which may be linked to the ECM to master the functional reputation the engines along with 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’re usually made of zinc and they are meant to attract stray electrolysis. This takes place when stray voltage in the electric system of a boat is transmitted with the metal aspects of the boat looking for a ground. The anodes can now be sacrificial and absorb the stray current and gradually deteriorate. This procedure is magnified in brine. One or more times per year, you can examine your anodes for decay and replace those that seem to have decayed greatly. Replacement anodes are not tremendously expensive and so they will protect your boat from some serious decay of some very costly metal marine parts.

If a marine engine is correctly maintained, it ought to offer you years of trouble free operation. It should be imperative that you one to know a qualified marine technician in your area. As with most things, “An ounce of prevention will be worth a pound of cure”.
