Load and Heat
Imagine driving your car at 80 mph while pulling a boat while driving up a 30 degree incline—all the time. That’s the kind of stress your outboard engine is under. Automotive oil is simply not designed to withstand the marine environment. Period.
Typical auto oils don’t contain corrosion inhibitors marine engines need to guard against the uniquely harsh environment that marine engines operate in. In the example to the right, samples have been cut from the actual cylinder walls of marine engines that were run with automotive, typical marine and Quicksilver oil. As you can see, the Quicksilver oil offers the best protection against corrosion.
Automotive engine oils are designed to operate in wider outside air temperature ranges than marine oils. In order to operate as efficiently as possible over these large temperature ranges, automotive oils use viscosity improvers (VI). This is a bit of an oversimplification, but VI are added so that oil can be as thin as possible while still meeting desired performance characteristics over wide temperature ranges. But VI aren’t necessary in marine engines because it is more beneficial for marine oil to be as thick as possible but still operate efficiently.
Premium 2-Cycle Outboard Oil
Protects and helps extend the life of small horsepower, outboard engines. Continued use of this oil also helps:
Prevent corrosion of internal components
Maintain peak engine performance and reliability
This all weather formula provides protection in temperatures down to -13°F (-25° C).
Recommended for use in premix applications for low horsepower, carbureted engines such as outboards, personal watercraft, snowmobiles, motorcycles and chainsaws.
Meets all outboard and personal watercraft manufacturers’ warranty requirements and recommendations for use of a TCW3® oil
4-Stroke Synthetic Blend Marine Engine Oil
Synthetic Blend oil is often recommended for marine engines used in racing. High performance oil provides maximum lubrication for your marine engine.
3 things to know:
Maintains viscocity under the most extreme operating conditions such as: Racing – operating engine at maximum output and hight temperatures and Tow Sports & Fishing- alernating between periods of high RPM’s and throttling down to low RPM’s or idle.
Protects against varnish buildup and sludge formation
Exceeds the rust protection requirements for NMMA certification
Syntehtic Blend recommended in Mercury Verado and all other high performance marine engines.
2-4-C Marine Grease
Quicksilver 2-4-C marine grease is a high quality, versatile lithium-based, NLGI 2 grease taht won’t break down when mixed with water. It also has:
Excellent resistance to oxidation and degradation
Extreme pressure additives to withstand friction in a wide variety of operations and temperatures
For use in the following marine applications:
Steering systems/cable linkages
Throttle and shift cables and linkages
Tilt lock mechanisms/tilt tube
Boat trailer wheel bearings
