30 years in the past American producers dominated the outboard motor market.Names equivalent to Mercury, Johnson, Evinrude and Chrysler, led the sector competing with one another to provide greater and higher outboard engines. Nonetheless, whereas this was occurring they had been neglecting the smallest of the outboards. These are the outboard motors that promote within the best of numbers and are sometimes the primary outboard many people, purchase. This being the case many people stick with the identical model (model loyalty) as we purchase different greater outboards through the years. The Japanese seized on this reality and steadily Honda, Yamaha, Suzuki and Tohatsu concentrating on small outboards started to take over as market leaders. They achieved this domination by bettering effectivity and reliability. In addition to including options to those small outboards beforehand solely discovered on bigger engines.
Having achieved success within the small outboard market, these Japanese producers expanded up the ability vary. They once more got here to dominate the outboard engine market as much as no less than 20 hp. The American producers as an alternative of competing with the Japanese, gave up and determined to purchase these engines from the Japanese and badge them as their very own. Now the Chinese language have entered the market. Principally doing what the Japanese did beforehand, copying the most effective options of the current engines and on the similar time conserving prices down.
So allow us to examine the outboards which might be on supply for these on the lookout for an outboard motor for his or her dinghy. If we take a reasonably bigger dinghy say, a Pioner 12, so that every outboard has to push a fairly heavy weight by the water. If we then take the next outboard motors :
Mercury 2.5hp; Mercury three.5hp; Mariner 2.5hp; Tohatsu three.5hp; Yamaha 2.5hp; Suzuki 2.5hp; Honda 2.3hp; and a Parsun 2.6hp. All these outboards are four stroke engines. This is because of an E.U. Directive that stops 2 strokes from being bought within the E.U. These outboards will present a reasonably wide selection of engines obtainable in the marketplace, for powering dinghies outboard engines for sale.
To guage one engine in opposition to the one other a number of checks had been accomplished. A Bollard pull check confirmed that the Mercury three.5hp and Tohatsu three.5hp had been probably the most highly effective at 90lbs of thrust (These two engines together with the Mariner are just about similar). The least efficient was the Honda 2.3hp at 66lbs of thrust. In between had been the Suzuki 2.5hp at 83lbs of thrust, the Yamaha 2.5hp at 78lbs of thrust and the Parsun 2.6hp at 70 lbs of thrust.
Subsequent check was Gas Consumption. At full velocity – 5.75 knots, the most effective outboards had been the Yamaha 2.5hp and the Suzuki 2.5hp by no less than 20%. The worst was the Parsun 2.6hp. When the throttles had been eased and the dinghy was cruising the Gas Consumption comparability was much less evident, solely about 10% distinction. All these figures are for four stroke engines. Nonetheless, primarily based on figures beforehand recorded for two strokes underneath comparable circumstances, the older engines had been as much as 50% much less gas environment friendly at full velocity. Very thirsty! Keep in mind 2 stroke outboards are nonetheless obtainable second hand.
Then the burden of every outboard motor was in contrast. 4 stroke engines are heavier than older 2 strokes due to the powerhead and so forth. The Mercury, Mariner, Tohatsu, Yamaha and Parsun all weighed approx. 38 – 41 lbs (18 kg.). Nonetheless, the Honda 2.3hp and Suzuki 2.5hp weighed lots much less at 28 lbs (12.5 kg.).
