Now that we have gone over the two cycle oil and gasoline specifications, as well as the benefits of the outboard motor, it is time to determine which model is right for you. The motor that you choose will be largely dependent on the hull of the craft that you plan to attach it to. Every boat built in the US has a “Guard Rating Plate”; this shows the maximum horsepower for the motor, but you should also be sure never to go below 75 percent of this number.
The other main spec to take into consideration is the shaft length. On outboard motors, this measurement is customized to fit 15, 20 or 25-inch transoms (the stern of the watercraft). When the shaft length is too long, there will be drag, while if the shaft is too short, it could lead to ventilation or potentially the overheating of the engine.
The two-stroke v. four-stroke debate is an ongoing point of contention between boat owners around the globe. While four-stroke engines certainly have their advantages, two-strokes are ideal for small watercrafts. In the next couple of days, we will be going over the various elements of the two-stroke engine and in what ways it is superior to the four-stroke.
When comparing the two, the most discernable difference for most people is how you mix the gasoline and outboard motor oil. In a two-stroke engine, the oil and the gasoline are mixed together, whereas they are held in separate compartments in a four-stroke. This design makes the two-stroke simpler but provides better lubrication to the four-stroke.
Our focus in this blog is obviously on oil, and, to a certain extent, outboard motors. When purchasing a new boat, one of the most crucial decisions is whether to go with an outboard, inboard or inboard/outboard motor. While the other two certainly have their merits, outboard motors are my weapons of choice for a variety of reasons.
First of all, and probably most importantly, they are the cheapest option. They also tend to be lighter, and you can easily remove them when not being used, making them simple to replace as well. Traditionally, outboard motors were two-stroke, which meant that you had to mix the outboard motor oil and the gasoline; however, today there are several four-stroke options.
I know that it is only March, but I am already beginning to prepare for the upcoming boating season. The weather here is already beginning to reach temperatures that make a weekend boating excursion look attractive. Of course, before I launch my watercraft for the first time, some routine maintenance and checks need to be done.
Before embarking on the first boating trip of the year, I always check the fuel line for cracks, wear and loose attachments. I also check the tanks for any damage and ensure that there isn’t any water in the fuel. And, of course, I always double-check the levels of fuel and outboard motor oil.
Every engine needs oil to maintain proper lubrication and preserve the integrity of the various moving components. This is particularly important for marine engines because of two factors that cause an unusual amount of wear and tear. First of all, outboard motor motors constantly run at a high RPM, and, on top of that, have to maintain their torque through waves and adverse conditions.
The fact that boats often go weeks, months or, in some cases, even years between uses doesn’t bode well for them either. Because of these constant strains on the engine, it is crucial to perform routine maintenance and change your outboard motor oil frequently. This will not only improve your boat’s performance, but will also prolong its life.
For those of us who aren’t certified mechanics or spend every waking moment doing research on our vehicles, choosing the proper parts and products can often be a guessing game. When it comes to your outboard motor oil, however, there is no need to make guesses. There are testing associations in both the US and overseas that work to ensure oils meet certain standards and specifications.
In Europe, this group is comprised of 13 major manufacturers and known as the European Automobile Manufacturers Association, or the ACEA. Their US counterpart, the American Petroleum Institute (API), includes over 400 corporations and is responsible for producing service categories. In additions to the API, the US also has the American Society of Testing and Materials (ASTM), which set limits on oil quality. Tomorrow we will go into more specifics about each organization and take a closer look at the information they provide.
Most manufacturers recommend changing your outboard motor oil and filter after every 100 hours of use or every season, which ever comes first. Some people may postpone this task, but it is essential if you want to prolong the life of your boat and achieve optimal performance. Changing your oil may seem daunting, but with a few wrenches and some knowhow, you can get the job done in no time.
Always remember to drain all of the old oil before refilling the crankcase. Mixing old and new oils will leave deposits in the system and limit the effectiveness of the new oil. Also, be sure to add a quart of oil for the new filter and run the engine when you are done to ensure that the oil pressure is correct and there are no leaky areas.
In this blog, we often explore some of the more advanced aspects on engine maintenance and may overlook the primary purpose of this site: outboard motor oil. Most of us know that the oil’s primary objective is to act as a lubricant for the various components of the engine. This lubrication is necessary due to the amount of heat and corrosion imparted on the various parts during the engine cycle.
Any two things that move against one another cause friction, and in the case of an engine, there is constant friction between the many moving parts. The oil works to facilitate the movements and reduce the amount to friction between the parts. In addition to acting as a lubricant, the oil also removes deposits and promotes energy savings.
Yesterday we reviewed some of the pre-ride checks that you should go through every time you ride your motorcycle — primarily, checking the levels of gas and outboard motor oil. There are some other basic systems that should be checked and adjusted on a regular basis to ensure the longevity and optimal performance of your vehicle; we suggest checking these systems on a daily basis. These include the throttle lever and over ride system, as well as the brake lever.
Also inspect the starter rope, engine start switch and all of the drive track and slider elements. Whenever heading out on a ride, be sure to bring a spare belt and plugs with you. Although it doesn’t need to be check on a daily basis, the chassis lubrication should be verified a few times season to preserve the various suspension and steering components.
The carburetor is one of the most vital components of any two-stroke engine, as it works to blend the air, fuel, and outboard motor oil so that they can be utilized in the stroke cycle. For many owners of two-stroke engines, however, carburetor maintenance and mechanical issues are a headache. The next few days we will go over the basics for making routine adjustments to the carburetor.
Always start by adjusting the idle, which controls the RPMs that the engine runs at. Set the idle speed to the proper RPM level by adjusting the idle screw. Next, turn the idle mixture screw so that the engine runs smoothly, with the optimal speed and response. Once this is done, make any final adjustments to the idle screw that may be needed. Tomorrow we will continue reviewing carburetor adjustments.
