How’s Your Engine Running?

After owning a four-stroke Mercury Engine for the past 3+ years, I can recommend them as a reliable and powerful motor. Although if it weren’t for our pedantic maintenance of it, it may be a different story. But no matter which brand you own, it won’t last if you don’t look after it properly.

Precautionary boat motor upkeep enables safe boating and can keep your motor dependable for a long time. You don’t need mechanical skills to look after your motor. Follow these simple steps:

Regular Maintenance and After Each Trip:

  • Number one rule! Flush out the engine; most engines require the use of muffs unless you have a large drum of water. If you are a novice, check this site for help
  • When flushing, make sure it has enough water flow from the ‘pee hole’ The spurt of water should be warm, but not hot.
  • If the stream is not strong, you may have something stuck in the outflow tube, such as wasp nest. If so, without delay, shut down the engine to prevent overheating. Use a small piece of wire into the flow tube and work it back and forth.
  • Start the engine again and check the output. If that doesn’t solve the blockage, it may be that you need a new water pump.
  • Take the cowling off and check for rust, corrosion, fuel or water leaks. If you find leaks, refer it to your mechanic.
  • Spray with an anti-corrosive like WD 40 or Lanolin. Lubricate all the moving parts, such as the shift, throttle cables, carburettor valves, etc.

If you don’t use your boat at least fortnightly, to prevent stale fuel, after flushing the engine, disconnect the fuel line and allow the engine to burn all the fuel in the carburettor. After that, be sure to turn off the key and, if you have a battery switch, turn it off. If the boat is only used in certain seasons, empty the fuel tank and use elsewhere or take it to a recycling station.

Personally, we use the engine all year round, which prevents old fuel, and if not, we flush the engine each week until the water runs warm, and take it for a service at the recommended hours.
