What Does Motor Oil Do? Part Three

One of the functions we don’t usually associate with marine engine oil is cooling. In most vehicles, the antifreeze concoction in the cooling system only does about 60% of the work when it comes to cooling the engine. Not only does oil cool the engine as it pulses through the system, it also controls the temperature by reducing friction.

Many of the grooves and spaces in-between the fittings on the engine leave microscopic openings in the system where pressure normally would be able to escape. However, the oil works its way into these gaps and creates a seal, effectively improving the engine’s efficiency. Additives in the oil now help reduce foam, allowing the oil to function to its full capabilities.

What Does Motor Oil Do? Part Two

Not only does Evinrude outboard oil provide lubrication to the engine, it also reduces friction between the parts. It’s important to find a medium with the viscosity of the oil you use; if it’s too thick, the engine will have to work harder and you’ll lose power and efficiency. The lubrication and friction reduction produced by the oil helps to prevent rust and corrosion throughout the engine. In addition, premium oil will eliminate carbon deposits and prevent sludge buildup.

When sludge forms in the engine, it prohibits the flow of oil, compounding the damage. Part of the sludge is formed when oil reaches the hottest parts of the engine and burns—at least until recently that is. New additives have made oil burn cleaner, helping to reduce buildup in the system.

Boat Engine Maintenance 101: Cooling System

Most systemic problems with boat engines can be traced back to a neglect of the cooling system. The cooling system in your boat will function much differently from the one in your car, so it’s important to be familiar with the discrepancies. Regardless of what type of cooling system you have, the water you’re floating in will be used to regulate the temperature of the engine, which means that all of the debris, algae and gunk in the water will now be pulsating through your boat.

The first way to prevent damage to the cooling system is to inspect, clean and replace the filters on the water intakes regularly. This will help you catch any large debris from the water that would otherwise be sucked through the system. If you are boating in salt water frequently, gasket failure will be your chief concern. When you see any signs of rusting or corrosion here, immediately switch out the parts and work to remove any deposits. In addition, changing your outboard motor oil regularly will help rid the system of deposits and keep the engine temperature in an acceptable range.

Boat Engine Maintenance 101: Making a Plan

Every boat owner—without exception—needs to know the fundamentals of engine maintenance in order to prevent long-term damage and have the ability to make adjustments when they’re on the water. Before we delve into the specifics, it’s crucial to get an understanding of the end goal of engine maintenance. Not only do you want to prevent long-term corrosion and wear, you also want to ensure that your boat is performing at its maximum capacity.

The biggest catch-22 about engine maintenance is that although your vessel is constantly in the water, water—and salt water in particular—is the engine’s worst enemy. Water is corrosive in and of itself, but it also facilitates the growth of fungus and other microbes. To that end, it’s imperative that you maintenance plan includes measures to prevent corrosion and protect against water damage. Over the next couple of days, we’ll be covering everything from how to mix your gasoline and outboard motor oil, to basic steps you can take to maintain your cooling system.

How to Operate a Boat: Shifting, Steering and Stopping

Before you push away from the dock and open up the throttle, be sure you have reserve gasoline and outboard motor oil on your vessel. If you’re operating an outboard motor, the throttle arm will also act as a tiller. Remember, the boat will go in the opposite direction that you point the tiller. You should be able to get the hang of it rather quickly when you’re going forward, but be sure to exercise extra caution if and when you have to back up. Once the throttle arm is turned to “run” or “shift,” adjust the shift lever and turn the throttle handle until you reach your desired speed.

Unlike your car, a boat doesn’t have brakes. The only way to reduce your speed is by lowering the power, which is actually quite effective due to the immense resistance from the water. And don’t try to stop on a dime. Shift the engine down to neutral well before your stopping point. If need be, you can give it a little more juice to get your all the way there.

How to Operate a Boat: The Basics

Whether you just bought your first boat or just plan to ride along as a passenger, learning the boating basics is a good idea for anyone who is going to be out on the water. Even if you aren’t planning to drive, you never know when an emergency will arise—or the skipper will want to take a turn being towed.

If you’re not riding in your own vessel, be sure to learn the basics of the craft when you get on. This should include locating the fire extinguisher and emergency supplies and learning how to start it up—although you should be able to do that after our crash course. Over the next few days we’ll be covering the essentials of boating—from how to properly check outboard motor oil and gasoline, to basic driving operations.

Motor Oil: Mineral or Synthetic?

There are three basic categories when it comes to outboard motor oil: mineral, synthetic and semi-synthetic. Mineral oil is the traditional stuff that is drilled and refined straight from the earth. Synthetic oil is comprised entirely of manmade chemical compounds. Semi-synthetic, as you can probably ascertain, is a combination of the two aforementioned types.

So which is the best type? Synthetic oils have the upper hand because scientists have the capability to design the oil to their exact specifications. This allows them to create oil that works well in virtually any conditions and runs cleaner than mineral oil. There used to be the notion that switching from mineral to synthetic or vice-versa was detrimental to your engine, but current research has shown that you can switch back and forth without causing any damage.

Motor Oil: What is Sludge?

Sludge has been a star of gasoline ads for the last several years, but do you even know what it is or why you need to be protected against it. Oil will oxidize over time, and when this happens the additives in the oil separate out. These additives consequently breakdown and solidify, then are heated and turned into a gooey, viscous substance we now refer to as sludge.

The obvious question is how do you get rid of and prevent sludge; and unfortunately there’s no easy answer. Flushing the engine can be effective, but you also risk simply flushing the pieces of sludge to a more recessed part of the engine. The best way to handle sludge is by preventing it in the first place. You can do this by changing your oil regularly and only using premium products like Evinrude or Yamaha oil.

Getting to Know Your Vessel

Last weekend I went out fishing with some old buddies on Elliott Bay in Puget Sound. One of the guys had just purchased new boat, so naturally I was intrigued about the vessel. The first thing I noticed was the Evinrude name plastered on the side of a large outboard motor, which is always a good sign.

As I began talking with him about the boat, it quickly became apparent that he didn’t have a solid understanding of boat maintenance. He’s a first time boat owner and had failed to even consider which type of outboard motor oil he was going to put in the engine. Over the course of the day I took every opportunity I could to bestow a few fundamental pointers on him. We’re going out again next weekend, so maybe I’ll show him how to do some simple maintenance in exchange for all the free beer he gave me the last couple of days.

Winterizing Your ATV: Part Four

Yesterday we discussed the importance of using premium synthetic oil in your ATV, but we neglected to say what to look for. The criteria for a premium ATV oil is much the same as outboard motor oil; in cold weather conditions the pour point is the most critical variable, which tells you the lowest temperature at which the oil will be effective. Once you have filled your engine with top-tier oil, it’s time to check out the battery.

Particularly if you are just taking the machine out of storage, it’s a good idea to check the battery to ensure the charge is adequate. You may need to attach the unit to a charger if it is low, but be sure to make sure it holds the charge before your head out. The fuel tank has a tendency to collect condensation in cold weather, which then has the potential to freeze, so be sure to keep the tank as full as possible at all times.

Winterizing Your ATV: Part One

Now that we’ve got the boat stowed away for the winter and have dealt with all of the necessary fuel and outboard motor oil chores, it’s time to start thinking about getting your winter vehicles out of storage. My family has an assortment of vehicles for soggy, cold conditions, but my favorite has to be our fleet of ATVs. Of course, you can’t simply take these vehicles out of storage and begin tackling the terrain immediately.

Just as you have to winterize a boat for storage, you also need to go through a winterization process before exposing ATVs to frigid climates. Over the next few days, we’ll be covering some of the basics of this winterization process to ensure your engine doesn’t seize up. We’ll also touch on some of the basic maintenance procedures that should be performed regularly, especially when starting up your machine for the first time since it’s been in storage.

Winterizing Your Boat: Part One

Now that the summer boating season is winding down, it’s time to start thinking about putting your boat in storage for the fall and winter. You may assume that you can simply throw your boat on the trailer, put the cover on and let it sit for months on end. This may work for a season or two, but eventually this sort of neglect will begin to cause damage to your vessel.

It’s critical to take some time at the end of each season to make sure your boat is stowed properly. Not only will this improve its longevity, it will also make your job easier when it comes time to get it water-ready next spring. Over the next few days will go over the proper protocol for handling the cleaning, outboard motor oil removal and other crucial components of boat winterization.
