Your Guide to Longer Motor Life
The key to longevity in your Mercury Marine motor is proper care. While these outboards are some of the highest-rated and most dependable, a lack of attention will lead to decreased performance and a shortened life span.
However, knowing the proper steps to care for your outboard can be overwhelming. So, we’ve compiled the top Mercury Marine 40-60 HP four-stroke maintenance guides. These short videos show you exactly how to maintain your motor through a freshwater flush, changing the engine oil, changing the fuel filter, and changing the gear lube.
Mercury Marine Freshwater Flush
What You’ll Need
- Freshwater supply
- Garden Hose
Why It’s Important
After boating in saltwater or brackish water, failing to flush your Mercury outboard with freshwater will lead to corrosion in water passages. This leads to a failing cooling system and decreased engine life.
Changing Engine Oil
What You’ll Need
- Socket Wrench
- Drain Pan
- Oil Filter Socket
- Oil Filter
Why It’s Important
Oil properties change over time, whether your Mercury Marine motor is being used frequently or not. Changing the oil prevents it from becoming acidic and destructive to internal engine parts.
Changing Fuel Filter
What You’ll Need
- Fuel Filter
- Drain Pan
Why It’s Important
Replacing your outboard’s fuel filter improves its ability to prevent foreign particles from clogging your engine. Diminished performance due to poor fuel filter quality begins when your engine runs too lean.
Changing Gear Lube
What You’ll Need
- Mercury High Performance Gear Lube
- Drain Pan
- Gear Lube Pump
- Socket Wrench
Why It’s Important
Gear lube lubricates metal-to-metal contact, preventing harmful wear to your outboard. Heavily loaded gears that aren’t effectively protected by gear oil causes expensive, sometimes irreparable damage.
