The choice of an outboard motor for inflatable boats


!±8± The choice of an outboard motor for inflatable boats

30 years ago, the American manufacturers dominated the market.Names as Mercury outboard motor, Johnson, Evinrude and Chrysler led the field in competition with one another to produce bigger and better engines outboard. However, while this was happening, they neglect the smallest of outboard motors. These are the most outboard engines sold in large numbers and are often the first outboards to buy a lot from us. That being the case, many of us to get the same brand (brand loyalty) asWe buy other major outboard motors over the years. The Japanese took this and gradually Honda, Yamaha, Suzuki and Tohatsu outboard motors on small concentration began to take over as market leader. They achieved this by improving energy efficiency and reliability. And the addition of features to find these small outboard motors previously only on larger engines.

After achieving success in small outboard market, Japanese manufacturers extended this power range. He returnedOutboard engines dominate the market until at least 20 hp. The American manufacturers instead of competing with the Japanese surrendered and decided to buy these engines from the Japanese and just as distinctive. Now the Chinese have come to market. Basically do what the Japanese have above, copy the best features of existing engines, while keeping costs low.

Then we compare the outboard motors that are on offer for the search of an outboard motor for theirDinghy. When you say a boat big enough, a Pioneer 12 so that each outboard weight high enough to push water around. If then the following outboard engines:

Mercury 2.5hp, 3.5hp Mercury, Mariner 2.5 hp, 3.5 hp Tohatsu, Yamaha 2.5 hp, 2.5 hp Suzuki, Honda 2.3hp and 2.6hp Parsun. All these outboard engines are 4 stroke engines. It is a directive of the European Union, which prevents two-stroke engines sold in Europe these outboards offer a fairly wide rangeEngines available on the market for the supply boats.

An engine of the other evidence against several judges have been completed. A bollard pull tests have shown that mercury was 3.5hp 3.5hp Tohatsu and (these two are almost identical engines with the Mariner) most powerful thrust to 90 pounds. The least effective was the Honda 2.3hp push 66 pounds. In the middle were the Suzuki 2.5 hp boost to 83 pounds, the Yamaha 2.5 hp to 78 pounds and push the Parsun 2.6hp £ 70Thrust.

Next test was the fuel consumption. At full speed - 5.75 knots were the best of Yamaha outboard motors from 2.5 hp to 2.5 hp Suzuki least 20%. The worst was the 2.6hp Parsun. When the handcuffs were removed and the dinghy cruising compare the fuel consumption was much lower, only 10% difference. All these figures are for 4-stroke engines. However, based on the previously recorded data for 2-stroke engine in similar circumstances, older engines up to 50% less fuelefficient at full speed. Very thirsty! Remember, two-stroke outboard engines are still available second hand.

Then, the weight of each outboard motor was compared. Four-stroke engines are heavier than the older two-stroke engine because of the powerhead, etc., Mercury Mariner, Tohatsu, Yamaha and all the weight around Parsun. 38-41 lbs (18 kg.). However, the weight of Honda and Suzuki 2.3hp 2.5hp long (12.5 kg.) Less than 28 pounds.

The price of each outboard motor was then compared. This would be difficultexactly as discounts and offers for sale are changing.

Mercury 3.5 hp £ 449
Mercury 2.5 hp £ 380
Mariner 2.5hp £ 429
Tohatsu 3.5hp £ 449
Yamaha 2.5 hp £ 489
Suzuki 2.5 hp £ 379
Honda 2.3hp £ 429
Parsun 2.6hp £ 375

Although the Parsun was the cheapest, and is practically identical with the same 2.5 hp Yamaha engine, not so good. It 'a little' like me for a recipe by Gordon Ramsay, the letterBut when compared side by side, just know that its a lot better. The Chinese are capable of copying, such as the Japanese did before them, but they have not entirely true, but!

Finally a little 'test on every outboard. Mercury, Mariner and Tohatsu have the same engine. The settings for the gas are easy to understand, with the throttle and stop button clearly marked. The fuel on / off tap water is not clearly identified. All these engines are passages. Forward andneutral, then with the turn to 360 degrees, you get the urge to poop. There are four tilt positions and a capacity of shallow water. Oil level can be easily checked by looking at the display on the side of the engine cover.

Yamaha 2.5 HP had simply start and stop settings understood, but the oil gauge was out of sight under the hood to cover. As with the Yamaha 2.5 hp outboard Mercury transitions before and neutral rotation of 360 degrees. Unlike Mercury, which hasa pin cut, Yamaha rubber on the propeller has a hub, so that no shear pins to break.

Suzuki 2.5 HP is as above but with the oil level indicator, slightly to the side of the lid. The propeller was placed with a cut-pin spare parts under the hood.

Honda 2.3hp is not water cooled like any other outboard tested. And 'air-cooled and has no transitions. Instead, it uses a centrifugal clutch. This makes it more difficult to start and operate than the others. It just takes a little 'get used to it. The oil pressure gauge is out of sight under the cover. The propeller has held a safety pin with spare parts under the hood.

Finally, the 2.6hp Parsun, a copy of Yamaha 2.5 hp is not as good. But it is the most economical engine is in new condition. The fuel was drawing his great return.
