Changing Lower Unit Oil on Mercury Outboard, Part II

Yesterday we began describing how to change the oil on the lower unit of a Mercury outboard. Picking up from where we left off, remove the upper vent plug and set it aside. Oil should now be flowing out of the lower unit and into the drain pan. This can take one to two hours for the unit to fully drain.

Take your supply of Mercury engine oil and dispense it into the lower unit. Continue adding oil until it flows from the top vent plug opening. Once that happens, replace the top vent plug and the drain plug. Let the oil settle overnight, check the levels in the morning, and add more oil if need be.

Changing Lower Unit Oil on Mercury Outboard, Part I

Changing the motor oil in the lower unit of a Mercury outboard is a fairly simple task. All responsible boat owners should, at the very least, know when to change the oil. After all, without the proper Mercury 2 stroke oil, the internal of components of the motor won’t work properly which can put you in a real bind if you’re out on the water when things go wrong.

To change the oil you will need an oil pan, screwdriver, rags, oil, and a utility knife. Once you have gathered your supplies lower the Mercury outboard to its vertical position. Place the drain pan under the lower unit and then turn the lowest plug counterclockwise with the screwdriver. Place the drain plug aside for the time being. Check back tomorrow for part II!

Cleaning a Carburetor

Sludge and other debris can clog the carburetor of a 2-stroke motor, so maintenance is a top priority. To clean a carburetor, start by removing the part from the machine. Spray the carburetor with specially made cleaner that will remove rust, sludge, and debris. Be thorough; there are plenty of valves and crevices in a carburetor that need to be cleaned out.

Once the cleaner has been applied, wipe the carburetor down with a clean cloth. With an air compressor, blow out any remaining debris. Once again, wipe off the carburetor and then reattach it to the motor. While working on the motor, be sure to check the oil level and add Mercury 2 cycle oil if need be.

Why Not Use Car Oil?

In the past, boat owners have used automobile oil to lubricate their outboard motors. If you really care about your boat, then it is best to use marine engine oil. Simply put, cars and boats have to operate in different environments and need oil that suits those environments.

To elaborate, boats, unlike cars, have a closed loop cooling system. Water causes corrosion, not to mention running a boat for an extensive amount of time can cause water and fuel build-up. That’s why marine engine oil, unlike automobile oil, has higher anti-corrosion properties

Starting a Flooded Johnson Outboard

What do you do when your two or four stroke engine is flooded? First off, don’t panic. A flooded outboard motor is relatively easy to fix. It just takes a little patience and know-how to get your to turn over.

Begin by pushing the choke to on and then turn the ignition switch. Next, bring the throttle to neutral then gradually to full and open. Pull the choke off, turn the ignition, and then crank the engine. Pull the throttle back to neutral and repeat the cycle until the engine is drained. When you get the chance, take a look at your engine on dry land, and add Johnson outboard oil if necessary.

Hampton Vacation

When people think of “The Hamptons” they think of wealthy New Yorkers with massive beach front mansions. While there are a number of wealthy New Yorkers who reside in the Hamptons during the summer, there are plenty of folks who call the Hamptons home year round. There are even more Americans who simply like to vacation there in the summer.

Personally, I like to spend a week with my family in Montauk in East Hampton. We get to enjoy the beach, Montauk sound, and great local flavor. If we can swing it, we’ll rent a boat for a day or two for cruising about and fishing. I’ve noticed that the rental shop uses Evinrude XD50 oil, which is what I would use, too, if I spent a lot of time out on the water.

The Environment and Evinrude

At the turn of the 21st century the Outboard Motor Corporation was not doing too well. As a result, the company was taken over by BRP. As part of the rebuilding effort, there was a re-focusing on making Evinrude motors more environmentally friendly, in accordance with the guidelines set forth by the .

The company did so well, in fact, that in 2005 the EPA awarded them the Clean Air Excellence Award for the advancements in Evinrude E-Tec technology. Evinrude has continued on the path of excellence. To maintain your Evinrude motor, be sure to use Evinrude XD100 oil.

Changing a Johnson Lower Unit Seal

The lower level of a Johnson outboard houses the water pump and propeller, among other important parts. Two seals keep the water out of the gears and keeps packed grease in, so if the seals become damaged in any way this can cause lots of problems. Therefore, when a seal is damaged it must be replaced.

Start by removing the cotter pin and then the propeller nut. Place the steering wheel puller over the propeller shaft, then lock the arms of the steering wheel puller and depress the bearing carrier off the gear case. Remove the damaged seal and pull out the old O-ring. Place the new seal into the bearing carrier and tap it into place with a mallet. Finally, spread grease on the seal. Don’t forget to replace the motor oil with Evinrude XD 50 oil!

1999 115 Evinrude Boat Specifications

In the early 1990s, Evinrude introduced the 115 horsepower engine. The Ficht-Ram model, introduced in 1999, featured an outboard design. The new design had better fuel efficiency, and therefore increased performance, when compared to other four-stroke engines.

The Ficht-Ram model uses 87 octane gasoline and is lubricated with Evinrude XD 100 oil. The recommended ration between the two is 60:1 or 300:1 depending on desired performance level. Once a year, the engine needs to be serviced to ensure continued high quality performance.

Winterizing a 9.9 Evinrude Outboard Motor, Part I

Winterizing an Evinrude 9.9 outboard motor may seem expensive, but failing to do so will cost more in the long run. Begin by washing the motor. Next, add one ounce of fuel stabilizer to the tank for each gallon of fuel the tank can hold. Run the mixture through the engine.

Flushing attachments, sometimes referred to as “earmuffs,” should be attached to a garden hose. Cover the motor’s cooling water intake with the earmuffs. Run the motor at 1500 rpm for five minutes. Stay tuned tomorrow for Part II of winterizing a 9.9 Evinrude outboard. Keep in mind that as it’s still summer, so continue using Evinrude oil to keep your boat humming along for the rest of the season.

Troubleshooting Johnson Outboard Engine

Wear and tear occurs with any piece of seaworthy equipment, even equipment made by Johnson. Troubleshooting a Johnson outboard engine is fairly simple. Start by checking the fuel tank for low fuel, broken or damaged lines, and test the rubber fuel primer bulb for hardness.

If that all checks out, then take a look at the motor’s spark plugs for corrosion or buildup. Replace any dirty or damaged parts. Run a compression pressure check; any reading below 60 PSI means that you should hire a mechanic because you have larger problems. Of course, replacing the oil with Evinrude Johnson 2 stroke outboard oil is an excellent means of keeping your engine in working order.

Reduce Outboard Smoke

At some point, every outboard motor smokes. To reduce the amount of smoke and the frequency in which it appears there are a few steps responsible boat owners can take. The first step is to add fresh fuel to the fuel tank.

The next step, and perhaps the most effective, is to change the motor’s oil. Replace old mineral oil with synthetic oil, like the Evinrude 2 cycle oil XD100. Synthetic oil runs cleaner, thus immediately reducing smoke. De-carbonizing the outboard motor also reduces the carbon build-up that causes smoking and poor performance.
