Several Uses Of Marine Engines
Fuel by itself is of no use whatsoever: it wants oxygen from the air outside to be able to burn. At essentially the most fundamental level, this takes place its own accord: as the piston falls during the induction stroke, air rushes in past the open inlet valve to fill the expanding space. Then, when the compression and energy strokes are complete, the exhaust valve opens as well as the rising piston pushes the exhaust gas out prepared for a fresh charge of clean air.
It's challenging being a boat engine! Unlike its automotive cousins, a boat engine is run at very high RPM's and beneath really a load when in operation and it sits in storage a whole lot of the time.
Water Pump Maintenance - Most marine engines are cooled by their pumping of lake or ocean water into the engine from a pickup inside the lower unit of the outdrive or outboard engine. As you may possibly expect, there are sometimes impurities inside the water or the operator (somebody else, I'm sure) that runs the lower unit aground plus the impeller picks up sand, dirt or other grit. These foreign substances wear on the impeller and sometimes trigger it to shred into pieces and fail. Also, if the engine is stored for a period of numerous months, often the rubber of the impeller gets brittle and cracks up. In any event, it truly is simply an excellent idea to proactively replace the impeller every 3-4 boating seasons.
Oil Change - Marine engines are ordinarily not run additional than 60-80 hours per year and, therefore, don't call for oil adjustments incredibly frequently. Usually, it's a great notion to change the oil (and filter) once per year at the end of the season. If the old, dirty oil is within the crankcase when the engine is stored in the off season, it can turn acid and damage the internal engine components it's supposed to protect. Of course, 2 stroke outboards have no crankcase and consequently no oil to change.
Fuel Injectors - Most newer marine engines are fuel injected and, when fuel is permitted to age and thicken during storage, the fuel injectors can effortlessly come to be clogged and may perhaps fail at the begin of the season.
In practice, though, the engine wants an air filter to quit dirt, moisture and bits of rubbish becoming sucked into its cylinders, and wants an exhaust system to dispose of the hot exhaust gases safely and quietly. To save having a separate filter and exhaust pipe for each and every cylinder of a multi-cylinder engine the incoming air is fed to the cylinders by way of tubular structures called inlet manifolds, and also the exhaust gases are carried away via related structures known as the exhaust manifolds.
Battery - If you take care of one's boat's battery, it will present you with numerous years of excellent service. You should take care whenever you total a voyage to make sure that all electrical components are turned off and, when you have a primary battery switch, be certain that it's turned off. Whenever the boat is stored for any prolonged period of time, the battery cables need to be disconnected.
Lower Unit Lubrication - The lower component of the outdrive or outboard engine is filled with a lubricant fluid that keeps all the moving parts correctly lubricated and running smoothly. The drive really should be inspected a minimum of annually to guarantee that the drive is full of fluid and that no water is present. This is relatively simple and inexpensive to accomplish.
Air filters
Unlike their cousins that energy tractors and earth-moving machinery, marine diesels normally operate in a fairly clean environment: there's small danger of them having to contend with straw, dust or roadside litter. This means that their air filters may be fairly simple, so some engines operate perfectly properly for years with little much more than a metal box with a few baffles in it.
Most, however, have one thing just a little additional sophisticated, involving either wire gauze or porous paper.
Paper tends to restrict the air flow, so to make up for this its area has to be increased by being folded into a concertina shape. It's also tricky to clean, so once a paper filter becomes clogged it has to be replaced with a new one.
Wire gauze does not restrict the air flow as much, but it is much less effective mainly because the gaps in between the strands of wire are larger than those between the fibres of paper.

Do you run LOP?
How many of you piston plane operators out there actually run LOP (lean of peak)
For planes equipped with a EGT (Exhaust Gas Temperature) gauge the standard for setting the mixture has long been to lean the mixture until the EGT has peaked then richen it back up until the EGT drops 50 degrees. So that would be 50 degrees ROP (Rich Of Peak)
Some people like myself will go ahead and lean some more after hitting peak, so that is LOP.
Many forums are full of arguments about the "great LOP/ROP debate".
This format is worthless for a discussion so I thought it would be interesting just to see how many people do run LOP here.
I fully believe in running LOP, but I don't have the equipment (or the guts, to be honest) to do it in my plane. I have a good friend with a Mooney who runs LOP and gets incredible fuel efficiency. I also have a neighbor who runs LOP (except when he's racing) and also calls ROP a joke for normal cruise.
By the way, if you read Lycoming's defense of ROP operations, you can see their arguments are unconvincing and foolish. Also, I was told by a Columbia Aircraft representative that the Pilot Operating Handbook for the new Columbia 400 recommends LOP operation. Good for them!
