Mercury outboard engines
For those that love the water, it is important to have a premium engine to service your boat. Mercury outboard engines are at the top of the line. You need an engine that is reliable, performs well and is good on fuel. With these things in mind, Mercury has created the optimum engines that include innovative technology to make sure your time on the water is great.
Mercury has the advantage because they offer you great benefits that begin with reliability and durability. Whatever engine you choose to use, consistent performance is what you get. This means that Mercury outboard engines are reliable. Another aspect of that advantage is the durability of the engines. Design technology puts the durability in the engine. Constant compression with rubber dampening minimizing the effects of the vibration of the engine reduces wear and tear on the engine.
Maintaining a constant flow of cooling water helps keep that durability. A Gearcase design that utilizes a heavy-duty prop shaft with double water pickups on the front of the torpedo makes this constant flow of cooling water possible. The inside engine components are protected by immediate lubrication on start-up. Using an oil system advanced to prevent oil drainback is part of the protection for the engine.
The stainless steel is used for the components for several reasons. It sustains saltwater and provides longer periods of time between maintenance. This reduces the cost to you in owning a Mercury outboard engine. The valve train that is featured in the Verado and the FourStroke engines is designed to be maintenance-free for life.
There are three optimum engines from which you choose. The Verado, OptiMax and the FourStrokes are designed for those of you looking for choice engines with specific individual features. The Verado has the marks for fuel efficiency and extreme performance. For the racer who wants power with minimized noise, this choice is for you. Without losing any power in the engine, you are in for the ride of your life.
The OptiMax features the direct-injected technology that offers you premium speed and acceleration. For the racer who needs top-quality performance at high speeds, this is a great choice. Handling at high speed is important for the race that requires top speed and the OptiMax has it.
Quality is the feature of the FourStrokes engine. Quality means that this engine is in for the long haul. Those of you who rely on the quality no matter how many times the boat goes out, this engine is for you. Quality is and always will be a priority for Mercury.
The engines described above offer something for everyone who thoroughly enjoys the water. Mercury outboard engines provide quality, durability and performance that is outstanding. Excellence in manufacturing outboard engines is part of what makes Mercury top in the industry. The safety of water sports is really critical. That is why quality is so significant. Safety is why durability is needed. Safety is why performance is essential. And, most important of all, that is why you can have a rich and enjoyable experience on the water with a Mercury outboard engine.

Aftermarket Mercury Propellers: Reliability
Boating enthusiasts who have a Mercury outboard engine know that the Mercury Marine company is dedicated to producing highly reliable propulsion systems. This is more than a matter of pride and convenience; it can be a matter of life and death for those who depend on Mercury boat propellers and outboards to get them safely back to shore. After all, if the propulsion system in your car should break down, you will almost certainly be on a known road. All you will have to do is push your car over to the side and wait for a passing motorist who can assist you.
Boats are another matter, particularly on the wide open ocean where it may be days or longer before a passing boat or ship comes close enough to see your watercraft and realize you are in distress. To be sure, a functioning communications system can go a long way toward promoting safety on the water, but it remains true that the best protection of all is to have a propulsion system that will not fail you.
It is quite normal, however, for one part of the outboard system to need replacing, and that is the propeller. There are several reasons why a boater might want to purchase spare Mercury boat props. Replacing a damaged prop is one motivation. Others include having one or two spare Mercury boat propellers on hand in case of emergency and buying a new prop because you want to fine-tune the fuel efficiency and performance of your boat.
Marine Propulsion: Performance Issues
The average boating enthusiast is quite interested in performance. One of the best ways to improve the performance of your watercraft is to be sure that you are using the correct type of propeller. Fortunately, many Mercury boat propellers are available as an aftermarket solution. There is no reason for boaters to tolerate inferior performance. They can improve speed and acceleration by looking carefully at Mercury boat props in search of the one that best suits their individual circumstances.
Other issues, however, can also impact performance. Boat buyers need to be aware that when a boat is sold, it is usually empty of extraneous gear. Sometimes it is stripped down to a large degree in order to reduce weight. Buyers should always keep in mind that they will probably use the boat in a much more fully loaded state, and that this change in weight will definitely affect performance. It is typical for all of the water, provisions, fuel, and even passengers to add enough weight to cut the top speed by three knots or more.
Another issue that can affect performance involves the bottom of the boat as well as any propellers. This is the issue of cleanliness. When the boat bottom or propellers are not kept clean, performance will be degraded. This is particularly true when the contours of the boat bottom are changed through the growth of organisms such as barnacles or snails. Keeping your boat clean means that
Mercury boat propellers will be able to perform at their very best.
Propeller Singing Remains Somewhat of a Mystery
Propellers are interesting objects. They are capable of propelling a marine watercraft at high speed, but they can also emit a high-pitched noise that experts term “singing.” All propellers can do this to one degree or another, including Mercury outboard propellers. The noise known as singing is not harmful in any way and does not indicate a problem with Mercury outboard props exhibiting this sound. Instead, it is merely a side effect of the mechanical action of the propeller.
What Causes Singing?
Strangely enough, even marine propulsion experts have not definitively nailed down the exact reasons why Mercury outboard propellers and other propulsion systems using propellers sing at some times and not at others. The instances of known singing tend to baffle these experts. For example, on a twin screw vessel where the propellers are singing, one of the propellers can be replaced by an identical unit – and oftentimes, this will stop the singing noise. This would seem to imply that there must be some infinitesimal difference between the two units, even when experts can find none.
What is known is that singing can result from particular combinations of boat speed, motor revolutions per minute, propeller diameter, and the thickness of a propeller blade’s trailing edge. The roundness of a propeller blade’s edge also appears to be a contributing factor. Thinner edges tend to exhibit less singing behavior, but then again, edges that are too thin are much more prone to damage.
Some boaters regard propeller singing as a charming side effect of motorized activity in any case.
Mercury Propellers: Three or Four Blades?
A cursory examination of the Mercury boat propellers available for sale will almost immediately raise the question of blades. Some Mercury props have three blades and some have four. How is a boating enthusiast, particularly a novice one, to know which arrangement is best?
The answer is that either one can be best depending on what the individual boater is trying to achieve with his or her watercraft.
Propellers with Three Blades
These propellers generally allow boats to reach higher top speeds, but they do not offer top acceleration levels. Therefore, it may take a bit longer for a boat to reach its top speed. Because these propellers have only three blades instead of four, they are less expensive to manufacture and can be more easily purchased by boaters on a budget.
On the other hand, propellers with three blades cause larger levels of vibration. The boat may go faster, but the pleasure cruise may be slightly less pleasurable because of vibration levels.
Propellers with Four Blades
An additional blade generally means more raw materials are needed for manufacture, which explains the slightly higher cost of most propellers with four blades. Top cruising speeds will not be quite as fast with these propellers, but acceleration will be better and operation will feel smoother to the boat driver and passengers because of reduced vibration.
This reduction in vibration and increase in acceleration is achieved in four-bladed models because there is more blade area cutting through the water.
