Cleaning Evinrude Outboard Spark Plugs

Cleaning Evinrude Outboard Spark Plugs

Still getting the boat ready for a day long fishing trip on the Angelina River and Steinhagen Reservoir. Today’s project was the remove and clean the spark plugs in the Evinrude 30 horsepower outboard motor. The spark plugs are probably 5 or 6 years old, and have not been cleaned since they were put in.

Somewhere around 2012 the boat was put in the shop to have a new powerhead installed. With the tuneup also came a a new water pump, and spark plugs.

Before the brutal Texas summer heat kicks in I want to launch the boat at Bevil Port, then head south on the Angelina River to Steinhagen Reservoir. Once I reach Steinhagen, turn north and head into the north end of the lake. The north-west area of Steinhagen is full of cypress trees. Hopefully, there will be some good fishing, or at least some good nature photography.

However, before the trip takes place, the boat needs to be gone over with a fine tooth comb. A couple of days ago I changed the oil in the Evinrude lower unit.

Fist step was to remove the cowling. This is the motor cover that has the Evinrude name and engine size on it. On the back side of the engine is a level that releases the cowling. Flip the lever, remove the cowling and place it somewhere out of the way.

The Evinrude 30 horsepower outboard motor has two spark plugs which require a 13/16 socket and ratchet to remove.

I only took one plug at a time out.

Remove the plug, then gently use a wire brush to remove any crud that has built up on the plug. I used a small stainless steel brush from a gun cleaning kit to scrub the crud off.

When I was happy with how clean the spark plug was, it was threaded back into the engine. The 13/16 socket was used to gently tighten the spark plug. Be careful not to over tighten the spark plug.

Then, the next spark plug was removed and cleaned.

It was an easy job that took around 20 minutes or so. What took the longest was walking to the shed to find the socket and ratchet.

Replaced or fixed so far:

  • New deep cell marine battery
  • New Starter button
  • Replaced starter solenoid
  • New fuel line going from the tank to the motor
  • Fuel tanks drained, dried, and cleaned
  • New wiring going from the battery to the starter
  • New trolling motor
  • Replaced wiring connectors at the battery
  • New on/off switch for the lights
  • Replaced lower unit oil
  • Cleaned spark plugs/li>

What’s Next

Next is to grease all the grease fittings on the motor, and grease the boat trailer wheel bearings.

Once the wheel bearings are greased, I think that about covers everything. The only thing left to do now is take the boat out on the river and spend the day fishing.
