While Evinrude may get a lot of publicity, Mercury Marine is actually the world’s leading manufacturer of marine propulsion engines. Unlike other companies that produce complete watercrafts, Mercury focuses exclusively on engines, providing units for recreational, commercial and government usage. The company creates both Mercury and Mariner engines.
You won’t see Mercury Marine on the NYSE, but that’s because they are a division of Brunswick Corporation, who also owns Bayliner, Sea Ray and other leading marine manufactures. In addition to their award-winning engines, Mercury also produces a wide line of accessories and Mercury oil. The Mercury Marines mission statement outlines their commitment to excellence and their customers.
Just as we take precautions to winterize our boat by changing the mercury oil, using a gasoline treatment to clean the tank, and greasing the propeller, it’s also important to winterize your boat trailer. The first step you should take is to prevent the buildup of rust, especially if your trailer and boat are stored outside. For rust protection, you’ll want to coat your trailer at least once every few years with rust prevention paint. It’s also important to re-grease the wheels on your trailer to avoid them from freezing and becoming immovable over the winter. If possible, drape your boat cover over the boat trailer as well, as preventing water runoff will help to maintain its condition.
With the proper precautions, you’ll be ready and rearing to go once the weather grows warmer; you’ll be out on the lake or the ocean before everyone else!
In 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.
Before picking up where we left off yesterday – greasing a few of the moving parts of the throttle – let’s quickly review what’s been done so far. We began the annual full-scale outboard tune-up by looking closely at the propeller for serious signs of wear and tear. Next, we looked for visible leaks around the propeller’s base. We added new marine engine oil to the outboard and replaced old lubricant in the motor’s lower unit with new.
Now it’s on to the throttle control – a crucial part of the boat that is used to determine fuel flow and, in effect, the speed of the craft. Start twisting the hand throttle around, watching the motor all the while and making mental notes of the moving parts. These should then be lubricated with standard marine grease. As always, the motor manufacturer may have a special suggestion as to which brand to use.
You’re now ready to disengage the sparkplug wires. Take special care to memorize where they are located and how they are positioned – that way you’ll be able to replace them just as they were. Take an adjustable wrench to each sparkplug and substitute it out for a new one. Tighten the new plug with your hand, then secure it fully with the wrench. Be forewarned that if you should overtighten the plugs, damage to your cylinder head could result.
Yesterday’s post about fuel flow meters got me thinking about other simple ways for boaters to save money in this uncertain economic client. If you can’t afford upgrade your boat’s meter and instrument panel at this time, there’s no need to despair. With a bit of discipline and ingenuity, you can help ensure that your marine vessel will never let you down in a pinch.
All boat manufacturers provide a recommended schedule of maintenance. This schedule is intended to give boaters all the information they need to keep the craft running at peak performance. Not surprisingly, the better you do at keeping up with routine maintenance, the less money you’ll have to pay for repairs down the line. Maintaining the engine should be made a top priority; if you neglect a marine motor you’ll end up spending more for outboard oil.
As is the case with automotive engines, a marine engine becomes practically useless if it’s allowed to overheat. Since outboards pull in water from the lake or river through an impeller pump, you’ll need to check this system and replace its components at regular intervals. Don’t skimp on crank case lubricants either as they keep the internal parts of the system running smoothly.
By now most small boat owners will be familiar with the debate raging in boardrooms and congressional halls over the merits of ethanol fuel. We’ve posted before about ethanol lobbyists whose primary goal is to force all boaters to use E15 fuel. And while most of their reasons for doing so are altruistic and pro-environment, the drawbacks of using high-ethanol blends in marine engines are myriad.
It’s not that boat owners are stubborn or set in their ways; to the contrary, they are often willing to embrace the latest technology if it promises to make their hobbies more fuel-efficient and eco-friendly. Unfortunately in the case of ethanol the detriments appear to outweigh the benefits. A process known as phase separation occurs when the ethanol present in blended fuel absorbs water and separates. This leaves multiple layers inside the fuel tank with the majority of ethanol and water – which won’t burn – settling down at the bottom. The marine engine oil remaining on top will have a lower octane rating.
Critics might argue that boat manufacturers need to overhaul their current fuel tank designs, but that problem would do nothing to assuage vintage boat owners or other 2-cycle motor users. Snowmobiles, go karts and chainsaws all feature engines that would be put at great risk if high-ethanol blended fuel entered into the equation. For now it’s up to individuals to make wise choices when selecting their boat oil.
