Have you ever wondered what really goes on inside your boat's fuel tank? At PartsVu, we had this same question, so we went to the local gas station and picked up a gallon of regular 87 unleaded gasoline and brought it back to our shop for some experimentation. The results, as shown in the video, were concerning and clearly demonstrate the need for a comprehensive fuel-treatment program.
Every boat owner wants their pride and joy to last a long time and to operate at peak performance. However, one of the areas that is often overlooked is fuel system care and maintenance. Fortunately, most boat owners pay very close attention to their engine oil. Outboard engines operate under extremely high-stress conditions, so proper lubrication is vital. However, your fuel system should be treated with the same consideration as fuel, like engine oil, circulates throughout your outboard engine and degraded fuel will leave damaging deposits throughout your fuel system and engine causing excessive wear and tear reducing engine performance and fuel efficiency.
Mercury Marine has a simple three-step system to assure that your engine is protected from the damaging effects of fuel breakdown.
Boating is not often thought of as a harsh environment, but in fact it is one of the most demanding environments in which an engine can operate.
Marine engines can and are often used for extended periods at wide-open throttle (up to 6400 rpm on some models), in harsh saltwater, and intense UV sunlight. Then, marine engines sit in storage over the off-season, in many cases without any use.

Most boats come with a 3-blade prop, which works. However, 4-blade props greatly enhance the performance of heavier, multi-species fishing boats like walleye boats.
Bass tournament anglers like Mark Zona, who load their boats with the latest fishing technology require a propeller that
will help them reach top speeds ahead of the competition. The Fury 4 has four high-progressive-rake blades made of Mercury’s X7 Alloy for additional lift and superior top speed on heavy, tournament-loaded bass boats. See why Mark Zona uses the Fury 4 blade propeller.
