Choosing An Outboard Motor

Choosing An Outboard Motor

30 years ago American producers dominated the outboard motor market.Names akin to Mercury, Johnson, Evinrude and Chrysler, led the sector competing with each other to produce bigger and better outboard engines. Nonetheless, while this was happening they have been neglecting the smallest of the outboards. These are the outboard motors that sell in the greatest of numbers and are sometimes the primary outboard many of us, buy. This being the case many of us keep on with the same brand (brand loyalty) as we purchase other bigger outboards over the years. The Japanese seized on this reality and gradually Honda, Yamaha, Suzuki and Tohatsu concentrating on small outboards started to take over as market leaders. They achieved this domination by improving efficiency and reliability. As well as adding features to these small outboards previously only found on larger engines.

Having achieved success in the small outboard market, these Japanese manufacturers expanded up the facility range. They again got here to dominate the outboard engine market up to at the very least 20 hp. The American manufacturers instead of competing with the Japanese, gave up and decided to buy these engines from the Japanese and badge them as their own. Now the Chinese have entered the market. Basically doing what the Japanese did beforehand, copying the very best features of the current engines and on the identical time keeping prices down.

So allow us to evaluate the outboards which might be on supply for those searching for an outboard motor for their dinghy. If we take a fairly larger dinghy say, a Pioner 12, so that every outboard has to push a reasonably heavy weight by way of the water. If we then take the next outboard motors :

Mercury 2.5hp; Mercury 3.5hp; Mariner 2.5hp; Tohatsu 3.5hp; Yamaha 2.5hp; Suzuki 2.5hp; Honda 2.3hp; and a Parsun 2.6hp. All these outboards are four stroke engines. This is due to an E.U. Directive that stops 2 strokes from being sold within the E.U. These outboards will provide a fairly wide range of engines available in the marketplace, for powering dinghies.

To evaluate one engine towards the one other several tests have been completed. A Bollard pull test showed that the Mercury 3.5hp and Tohatsu 3.5hp had been the most highly effective at 90lbs of thrust (These two engines along with the Mariner are virtually similar). The least effective was the Honda 2.3hp at 66lbs of thrust. In between have 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 test was Fuel Consumption. At full speed - 5.75 knots, the very best outboards have been the Yamaha 2.5hp and the Suzuki 2.5hp by at the very least 20%. The worst was the Parsun 2.6hp. When the throttles have been eased and the dinghy was cruising the Fuel Consumption comparison was less evident, only about 10% difference. All these figures are for four stroke engines. However, based mostly on figures previously recorded for two strokes under related circumstances, the older engines were up to 50% less fuel efficient at full speed. Very thirsty! Keep in mind 2 stroke outboards are still available second hand.

Then the burden of every outboard motor was compared. 4 stroke engines are heavier than older 2 strokes because of the powerhead etc. The Mercury, Mariner, Tohatsu, Yamaha and Parsun all weighed approx. 38 - forty one lbs (18 kg.). However, the Honda 2.3hp and Suzuki 2.5hp weighed quite a bit less at 28 lbs (12.5 kg.).

Though the Parsun was the most affordable and it\'s virtually similar the identical engine as in the Yamaha 2.5hp, it\'s not as good. It is a bit like me following a Gordon Ramsay recipe, to the letter, however when compared side by side you just know that his is going to be that a lot better. The Chinese are able to repeat, just just like the Japanese did earlier than them, but they have not got it proper, but!

Finally a little about each outboard tested. The Mercury, Mariner and Tohatsu are the same engine. Beginning settings for the throttle are straightforward to understand with the choke and cease button clearly labelled. The petrol on/off faucet isn\'t so clearly marked. All these motors have gears. Ahead and neutral then utilizing the 360 degree rotation you will get astern thrust. There are four tilt positions and a shallow water ability. Oil levels might be simply checked by viewing the indicator on the side of the engine cover.

The Yamaha 2.5hp also had simply understood beginning and stopping settings but the oil level gauge was out of sight under the engine casing cover. As with the Mercury outboard the Yamaha 2.5hp has gears, ahead and neutral with 360 degree rotation. Unlike the Mercury which has a shear pin, the Yamaha has a rubber hub at the propeller, so no shear pin to break.

The Suzuki 2.5hp is as above however with the oil gauge easily considered at the side of the cover. The propeller has a shear pin with spares stowed under the engine cover.

The Honda 2.3hp will not be water cooled like all the other outboards tested. It\'s aircooled and has no gears. Instead it uses a centrifugal clutch. This makes starting and maneuvering more tough than the others. It simply takes a little bit of getting used to it. The oil gauge is out of sight under the cover. The propeller has a shear pin with spares stored under the engine cover.
