Below I have listed some simple operating and maintenance practices for various
types of marine engines, which will greatly improve the reliability and life of
your engine.
Best boat motor repair practices |
For Inboard and I/O Applications |
-
After 50 hours initial engine operation, switch to Mobil 1 motor oil of proper
SAE spec for your engine. This step alone will more than double your
engines service life. Choose the best boat motor repair
in south florida, we only use Mobil 1 synthetic motor oils.
-
Replace Exhaust risers and gaskets every 150 hours of engine use(if salt water
cooled).
-
Replace Exhaust manifolds every 300 hours of engine use if salt water cooled,
500 hours if fresh water cooled. Risers and or manifold failure are the number
one cause of engine failure due to water ingestion and corrosion.
-
Use a fuel stabilizer such as 2+4 fuel conditioner, to stabilize fuel for
periods when the boat is not in use. This will keep your fuel system clean for
up to two years. Choose the

-
Replace your raw water pump every 50 - 100 hours or once a year.Replace the
housing too, not just impellers. Todays engines can't survive over heating.
Cylinder head failure in GM based engines due to over heating is an epidemic,
so keep your engine cool.
-
Replace gear oil and/or transmission oil every 100 hours. Inspect propeller
shaft seals for wear, fishing line etc and service every 250 hours or as
required.
-
Use a RACOR brand, fuel filter to filter your fuel and remove water. Check it
EVERY time you leave the dock.
For 2-Stroke or DFI outboard applications:
-
Use OEM marine lubricant in your oil injection system, they are not all the
same. Manufacturers have specific formulations designed for their specific
applications.
-
Refrain from operating your engine for long periods of time above 4500 rpm, not
only will you conserve fuel, you will prolong the life of your engine.
-
Select a propeller which will allow your engine to reach the top end of its
operating range, with your boat loaded the way you normally have it loaded on an
outing. If your engine is designed to operate at full throttle between 5500 -
6000 RPM, then selecting a propeller that allows it to turn 6000 RPM at full
throttle is what you want.
-
Replace thermostats and water pump every 100 hours of engine operation.
-
Use a RACOR brand, fuel filter to filter your fuel and remove water. Check it
EVERY time you leave the dock.
-
With todays fuel that is available be aware that 2 stroke engine oil does not
mix with ethanol. Most retailer gas stations are now using fuel with not more
than 10% ethanol. Unless OEM manufacturers are formulating oil for their
engines which will blend with these new fuels, we will soon begin to see major
engine failures due to lack of lubrication. This is another reason to make sure
to use only OEM lubricants in your fuel.
For 4-Stroke outboard engine applications:
-
Change water pump every 100 hours of operation.
-
Change crankcase oil every 50 hours. Use OEM specified oil with the proper SAE
specification.
-
Replace cooling thermostats every 100 hours of operation.
-
Use a RACOR brand fuel filter to keep your system clean and free of water.
Inspect it everytime you leave the dock.
-
Cruise at an operating RPM of no more than 80% full rpm range. This should be
approximately 4000 rpm on most engines.
For Diesel engine applications:
-
Replace all pencil zincs in the exhaust manifolds every 50 to 100 hours. If
your engine also is equipped with these anti corrosion inhibitors, replace them
as well.
-
Use fuel stabalizer and bio control additives to prevent growth in your fuel
tank.
-
Use high quality fuel filters such as Racor or Dahl and replace every time you
perform an oil change at 100 hour intervals.
-
Having an oil pumpout manifold will make changing oil a breeze and keep your
bilge clean.
-
Keep fuel or air shutdown solonoids for your particular engine, onboard your
vessel in a safe cool and dry place, like inside the salon. These solonoids
generally fail before anything else.
-
If you experience slow cranking speeds when initially starting, look at your
battery cables. If you flex them and they make a crackling noise, replace them.
-
Replace or have inspected, prollers and or shafts, if any vibration is noted
while underway. Do not operate the vessel any longer than necessary with a bent
shaft or propeller. The damage to your transmission will be severe.
