Guide for Selecting a Used Outboard Motor

outboard motor oilIn a perfect world, we would all be able to afford precisely what our hearts desire. There wouldn’t be much diversity in the boating world, as we’d all be cruising past each other in top-of-the line boats with high-end outboard motors attached to the transom. Just think of all the luxury and convenience we would experience on a daily basis. Unfortunately, we would also miss out on many of the great stories that make boating so much fun. Old, well-worn boats have a certain character that their new counterparts lack. To an extent, the same could be said for outboards themselves.

There are several considerations to make upfront when selecting a used outboard motor for your vessel. They fall into three main categories: age, accessories and brand reliability. First, be sure you understand the difference between age and use. An eight-year-old outboard that has lain dormant inside a garage will be in much better shape than a four-year-old engine that has been run hard and denied basic maintenance. Check to ensure that the motor in question operates with a TC-W3 formulation of outboard motor oil.

Choose the accessories that best complement your pre-existing boat. For instance, find a motor that features cable steering, an electric start and other features that make boating more simple if you have a boat that allows for it logistically. As a final consideration, do some research about the specific brand of motor in which you want to invest. The big names in outboards have remained the same for decades: Yamaha, Evinrude, Mercury.

Preventive Care for Outboard Motors

bulk-outboard-motor-oil1For most fishermen and fans of recreational water sports, a boat represents one of the most serious investments in one’s life. It generally comes down to a house, a car, and then a boat – in that order. So, assuming your boat is the third biggest financial investment in your life, doesn’t it deserve the sort of time and energy you put into your other prized possessions? After all, your home might be remodeled, repainted or at least cleaned each spring. And you wouldn’t think of driving your car much more than 3,000 miles without an oil change, would you?

While there aren’t universal rules about adding bulk outboard motor oil to the boat engine, it’s up to you to consult your owner’s manual for guidelines. When boating season begins, it’s best to take your winterized boat to a professional mechanic. After that, you should be able to handle post-trip routine maintenance. It’s important to always flush out the engine – whether you’re boating in salt water or fresh.

The only tools necessary for this task are a garden hose and a set of rabbit ears, or seals that slip into the lower unit of the engine. Take this opportunity to check the stream of water as it flows out of the pump. If it’s hot, there could be some debris jammed inside. This will end up taxing the engine too much, so it’s best to shut things down and root around inside the tubing for the source of blockage. After that, disconnect the fuel line and burn all the fuel in the carburetor.

Browsing for Used Boats in the Offseason

mercury-oilNow that winter is on the way and likely to stay in parts of America for the next several months, many boaters enter a planning stage. Since they cannot get out on the lake to go fishing or just to cruise around aimlessly, a number of thoughts begin to enter their heads. Foremost among these is the question of whether to buy a new boat. Every spring like clockwork, thousands of people show up at marinas and dealerships ready to make such a purchase.

From an economic standpoint, these last few years have been slightly different. The uncertainty of the job market has made some people wary about investing too much in luxury items. These concerns have led to a resurgence in the used boat market, convincing consumers to look at the bright side of an aging vessel. The key is to think about the purposes for which one plans to use the boat.

Fishing boats and those intended for recreational water sports feature a completely disparate construction. After you’ve narrowed down your selection to the type of boat, take a gander at the hull to check for structural damage. Then study the inner workings such as the outboard motor. Does it look like it’s been given plenty of mercury oil over the years? Signs of corrosion and leakage might be enough to keep you away from making the investment.

How Does an Outboard Motor Work?

yamaha_2_stroke_9_9Since their introduction in the early 1900s, outboard motors have revolutionized the way in which we think about boating. Prior to that, boaters and fishermen were largely dependent on the direction of wind or – for those who felt like using oars – brute force. Outboards have taken the focus of our attentions of locomotion, allowing us to think about catching fish or just enjoy the scenery.

Marine motors work in a deceptively simple way. Much like car engines, they generate power by burning gasoline and oxygen inside a cylinder. In the case of a boat, only one cylinder is generally used. The end result is that the engine powers a propeller submerged below the water’s surface and behind the boat. Two cycle outboard oil is applied to keep the motor properly lubricated and running smoothly.

So, it all starts in the cylinder where gasoline mixes with air, burns and creates power to move the piston back and forth. The piston rod connects to a crankshaft, which turns and causes the main driveshaft to turn as well. This long driveshaft is attached to a gearbox that converts the spinning motion into kinetic energy to move the propeller. Finally, the propeller pushes the boat through the water.

Fuel Tanks Beware: The Ethanol Issue

ethanolAs many boaters know, the Environmental Protection Agency has been cracking down of production of inefficient vehicles in recent years – whether they are designed to drive along roads or motor through a waterway. In some respects, the influx of restrictions and guidelines has been a good thing. After all, most boaters want to make as little lasting environmental impact as possible as they go about their hobby.

Unfortunately, all this eco-awareness has led the EPA and many government lobbyists to embrace the ethanol industry. Ethanol is drawn from corn and acts as an excellent solvent when added to regular fuel. It absorbs water, which can be a serious problem in automotive and marine fuel tanks alike. When much more than 10 percent ethanol is present in fuel, a layering effect occurs.

Most outboard motors are not capable of handling the lumpy layer of sediment that seeps to the bottom of a fuel tank when ethanol and water combine. For those with older, fiberglass fuel tanks, it’s best to avoid ethanol whenever possible and to use good water-separating fuel filters the rest of the time. Make sure to replenish your supply with fresh Evinrude outboard oil, and do your research before switching fuel types.

The Steady Evolution of Snowmobiles

yamaha-2s-oilThe first snowmobile-esque vehicle to be manufactured was intended for military and police transportation. In the mid to late ’50s, Bombardier created a rudimentary snow track machine capable of holding up to a dozen people. Needless to say, this machine bore little resemblance to the sleek, sporty recreational sleds of today. Bombardier released a more compact snowmobile in 1959; for the first time, such a machine was meant for public use.

It didn’t take long for Bombardier’s rivals to begin introducing rival sleds, and this influx of competition brought about plenty of technological innovation. The designs of early snowmobiles left plenty to be desired. They were underpowered to begin with, and their frames were the opposite of aerodynamic. High-performance 2 stroke engines were released as snowmobiles gained widespread popularity.

These 2 strokes, both then and now, were kept performing at peak condition with the help of Yamaha 2s oil. In recent years, the Environmental Protection Agency has cracked down on high-emissions vehicles. Rigid environmental guidelines forced some companies to make a switch to 4 stroke engines while other manufacturers found ways to improve efficiency of their existing 2 stroke formula.

Have You Winterized Your Boat?

mercury-engine-oilAs much as we might hate to admit it, most anglers are faced with an offseason that lasts at least several months. When spring comes around, we can start our love affair with the fishing boat all over again. Until then, it’s up to us to winterize and find other ways to pass the time – such as snowmobiling. But before you hop on that sled, let’s take some time to ensure that you’ve done all you can to winterize the boat effectively.

If possible, store your boat on land. This prevents the possibility of water seeping through the hull fittings or gate valves, freezing and expanding. Over the course of an entire winter, this can cause severe harm to the structure and cost you lots of money. Add anti-freeze to parts of the boat that are intended to contain water such as water tanks, septic holding tanks and toilets.

Drain the boat’s cooling system and add anti-freeze. Do so dipping the water intake into a bucket of anti-freeze and running the engine for a few minutes. The battery should be disconnected and stored on land. Drain the existing motor oil and replace it with Mercury engine oil. Drain and replace the transmission and outdrive oils and top off the tanks with a fuel stabilizer.

Snowmobiles Explained: Safe Sledding

snowmobiling1Today we conclude our week-long look at snowmobiles. It all began Monday with an exploration of a typical sled’s drive system. From there, we compared and contrasted snowmobile tracks with those of a tank. Yesterday we posted some brief thoughts on the environmental impact of snowmobiling and the importance of replenishing two cycle oil. Now let’s head even further down the trail to discuss safety tips.

As is the case with any vehicle, you must familiarize yourself with the terrain before deciding to see how fast you can go. You wouldn’t drive 55 mph in a car down a narrow residential street for obvious reasons. Even if you’re riding a snowmobile in a secluded spot, the quality and condition of the snow will make a huge difference. Snowmobiles are set lower to the ground than motorcycles, which might lead you to believe that there’s less risk of injury. Bear in mind, however, that the open sled design creates a very real possibility of falling off.

The most critical pieces of safety equipment for a snowmobiler are the helmet, gloves and boots. Gloves and boots help keep the extremities safe from frostbite, which can nip away at fingers and toes to make precision steering a difficult task. When sledding in a populated area, snowmobilers must be familiar with conventional hand signals – they’re very similar to the ones used by bicyclists. For example, a right turn is signaled by sticking the left arm straight out to the left. A right turn is signaled by pointing a bent left arm upward.

Snowmobiles Explained: Environmental Issues

snowmobile2In the past few days our discussion of snowmobiles has run the gamut from power systems to track mechanics and steering. Today, it’s time to take a step back from the nuts and bolts to see the forest for the trees. Just what are the environmental implications of recreational sleds, and what plans are in the works to increase engine efficiency? Unlike the environmental effects of automobiles and boats, those of snowmobiles remain understudied and to some extent uncertain.

The history of snowmobile engines reflects that of outboard motors in one key way. As recently as a few decades ago, both were being manufactured with little regard for their environmental impact. The amount and content of exhaust emitted by the engines was eventually deemed unacceptable, and the rise of four-stroke engines challenged two-stroke manufacturers like Yamaha to step up their game.

Today’s snowmobiles feature reduced emissions and increased engine efficiency. Where once speed and maneuverability were a sled’s main selling points, eco-friendliness has now joined the list. Modern-day snowmobiles run best on specially formulated 2 stroke oil. Snowmobile manufacturers continue to struggle with noise pollution concerns, however. Many sled makers have taken concerted steps to reduce noise levels.

Snowmobiles Explained: Staying on Track

2-cycle-oilIn yesterday’s installment, we took a look at the four main components of a snowmobile’s drive system: the engine, clutch, track and skis. We’ll shift gears slightly today to focus on the track in particular and the steering system in general. The track is designed to maximize traction as the sled moves along the snow. It could be likened to that of a tank, with one major difference: tank tracks are stiff and durable above all other considerations because of the role they play in warfare. Snowmobile tracks, on the other hand, are meant for optimal swiftness and maneuverability.

It goes without saying that snowmobile tracks are more effective on snow than wheels would be, but why is this so? The answer comes down to a question of physics. By spreading out the point of contact with the snow to a larger surface area, tracks create plenty of traction. The treads on the track are rough enough to create friction and grab onto the snow at regular intervals.

Snowmobiles steer in much the same way as other vehicles with handlebars. However, the steering system brings up another major difference between tank tracks and sled tracks. Tanks are often given outfitted with double tracks, which are charged with steering. Snowmobiles come equipped with twin skis at the front of the sled. The width and spacing of the skis make a significant difference when steering. Narrow skis allow a snowmobile to take sharp turns. Tomorrow we’ll take a look at the improvements that have been made to 2 cycle oil formulations.

Snowmobiles Explained: Powering the Sled

racing_snowmobileLast week we presented a four-part series on seasonal snowmobile maintenance – the kind of repair work that should be done even before the best powder begins to fall. This week, we’ll take it back to basics, explaining the ins and outs of the snowmobile from its drive system to its steering system, from environmental impact to safety tips. For those of you who already go snowmobiling on a regular basis in winter, this should prove a valuable refresher. For beginners, it aims to serve as a good informational starting point.

The sled’s drive system can be broken down into four essential parts: engine, clutch, track and skis. While some four-stroke engines are available in professional snowmobiles, lightweight models feature a powerful two-stroke. The engine links to the internal track drive, which in turn causes the tracks to rotate. In a way, snowmobile tracks are like those of a Sherman tank – except scaled down considerably, of course. Snowmobiles always benefit from a fresh supply of Yamalube oil.

The clutches are really a glorified pulley system that connects to the track drive and tightens the belt around the track. Most snowmobiles have a primary and secondary clutch. The secondary clutch comes into play once the sled has accelerated; it “shifts into another gear” once the wheels begin to turn and less effort is required on behalf of the motor. The skis are fastened at the front of the sled to provide stability. We’ll talk more about them in the entry on steering.

Snowmobile Maintenance IV: Carburetor Cleaning

snowmobile1Over the last few days, we’ve discussed the ins and outs of a seasonal snowmobile tune-up – from salvaging the upholstery to checking for exterior scratches and ensuring proper fluid levels. In today’s final installment, we’ll shift over to one of the most common causes of engine failure: the filthy carburetor. It doesn’t take much more than regular hand tools, a can of carb cleaner, some ingenuity and a willingness to get your hands dirty.

For those who don’t already know, the carburetor is the device charged with mixing air and fuel in an internal combustion engine. Commence the cleaning process by crimping fuel lines to prevent any leakage while you work. Remove any throttle cables that might get in your way, as well as the fuel lines. Loosen and remove the carburetor, then inspect it for residue.

If residue is found to be blocking the two main jets in the main carb body, place the carburetor in a bath of car cleaner. It should then be blown dry and inspected once more. Reverse the procedure to reinstall the carburetor. That’s it! Before hitting the trail, it’s never a bad idea to top off your snowmobile with Yamalube 2s oil. Happy sledding, and remember to drive safe.
