Many digital multimeters (DMM) have a diode/continutiy setting, often referred to as the "beep test".  This setting is designed to give an audible indication that a circuit is open or closed and, when combined with the Diode test, will display the voltage drop being measured.

When dealing with a motor that has experienced an internal failure, it is incredibly important to ensure that all internal components are completely cleaned before putting the motor back together.  Closely inspect all parts that are lubricated or use pressurized oil for debris.  If any contaminants from the failure arent cleaned out, they can quickly lead to repeat failure.

Team Goldberg takes on the challenge of updating a classic Magothy River marina — family-style.

Twenty-eight-year old JoAnna Goldberg is doing something few young women of her age are qualified to do: oversee the rebirth of an old-line Chesapeake Bay marina while at the same time helping her entrepreneurial father, Larry, expand the Freedom Boat Club concept throughout the state of Maryland.

Understanding voltage is a key element to troubleshooting electrical circuits.  Voltage is defined as "electric potential or potential expressed in volts" by Merriam Webster.  Voltage is nothing more than a measurement in the difference between two points.  If we measure the voltage of a starter battery using a Digital Multi Meter (DMM) we would see approximately 12.8 volts DC (VDC) for a charged battery.  That battery is able to exert 12.8 volts of electrical pressure.  A completely dead battery would measure at 0 volts DC and is incapable of exerting any

Dry corrosion occurs in areas not in direct contact with water - exhaust systems, for example.  The outside of most exhaust system components is cooled by raw water to prevent overheating.  When today's ethanol-enhanced fuel is burned, it creates by-products known as sulfate salts.  These salts are highly corrosive, especially when exposed to very hot temperatures.  If the outboard's cooling water passages are not kept clean by regular flushing (the exhaust area in this example), hot spots can form on the interior of exhaust components, concentrating the sulfate

10 micron filters should be replaced every fifty hours of enine operation.  Keeping this filter clean and fresh will help protect the other fuel filters on the engine and extend their service life.  Always carry a spare on board, just in case you get a load of bad gas and the filter gets overwhelmed.

Primary and in-line filters should be replaced every 100 hours of engine operation.  These are easy to get to and simple to replace.

FC-W is the minimum certification standard of the National Marine Manufacturers Association (NMMA) for marine engine oil.  Oils that earn NMMA certification have passed rigorous testing, and have been proven to provide the performance and protection demanded by today's advanced outboard technology.  These oils stand up to extended full-throttle operation, high loads, and the salt and moisture-rich air found in a harsh marine environment.

Proper storage of four-stroke outboards is critical for many reasons.  One more obvious reason for smoke during start up could be directly related to the position of the outboard during storage.  When storing four-stroke engines, either overnight or for any length of time, it's important to trim the outboards to a positive trim angle.  Here's why:

There are many parts of a propeller that affect the way it performs, but one that is commonly misunderstood is the cup.  Most often cup is confused for the dished out portion of the blade's face, or pressure side.  In fact, the cup is found along the trailing edge of the blade and the blade tip.  Cup is commonly modified by propeller repair shops, but how do these changes affect the propeller's performance?

Today's fuel injected motors with their computer control modules and high energy ignition systems place a high demand on the battery. Every engine manufacturer will provide you with the correct battery rating information for each model. Take for example you have a 2005 Yamaha 225 HP four stroke, the service manual list the minimum recommended battery capacity as: CCA-512 A, MCA-675 A, RC-182 Minutes.
