Features such as largest engine capacity displacement giving you more low-end thrust. Nothing on the water today is faster or more proven than the OptiMax Pro XS.
Rather than just going with the tried and true Yamaha listened and began to build motors that arent quite so noisy.
Does mercury still make 2 stroke outboards. Mercurys proven TwoStroke engines deliver easy starting gutsy performance and great all-round reliability. Across the range youll find an array of features that help keep your boating experiences more enjoyable and trouble-free. Features such as largest engine capacity displacement giving you more low-end thrust.
Many of the lower HP 25 to 40 HP Mercury 2-strokes are just rebadged Tohatsu 2-strokes. Yamaha also still makes and sells carburated 2-strokes just not in the US. And if you dont live in California where these motors are not available.
Back From The Dead The Mercury Classic 50. 2 Stroke vs. 4 Stroke Outboard Fuel Economy.
In the past 2 stroke motors burned more fuel than 4 strokes. However the 2 cycle product is now much more efficient in its injection methods used to bring fuel into the engine. Some companies claim to be more fuel efficient than others but in many cases its a matter of splitting hairs.
Today Mercury makes outboards from 25 to an astounding 600 horsepower. The variety of their outboards spans 2-stroke or 4-stroke jet engines and even models that run on propane. The most popular models are their 4-stroke outboards in the 30-60 horsepower range.
Rip mercury killed off all 2 stroke engines 4-1-18 As a guy who started with OMC lawnboy 2 stroke in 1973 and alaways had 2 stroke engines from dirt bikes to outboards its a sad day. Its official MERCURY NO LONGER MANUFACTURES 2 STROKE OUTBOARDS. David - WI thanked for this post 04-24-2018 0951 AM 2 JPEROG Supporting Member.
Yamaha and Mercury have stopped producing direct-injection 2-stroke outboards Tohatsu still builds a few but the latest-generation 4-strokes weigh. Yes I believe Tohatsu still makes all of Mercuries small motors. For awhile I think between around 92-98 or so either yamaha or tohatsu made small 2-stroke outboards for Mercury tohatsu and yamaha.
The old 6hp yamaha 2 stroke short shafts are awesome. I believe theres a couple of tohatsu dealer in Houston if you dont mind making the drive. So two-stroke engines make more power using fewer parts they weigh a lot less because of it and thanks to their simplicity backyard engine rebuilds are so easy a child can do it.
In fact a two-stroke engine makes nearly 30 more power than an equivalent displacement four-stroke. Mercury has a world-class aluminum casting plant but reserves it for making high-performance engines for themselves and other customers like GENERAL MOTORS who use these castings in their top-of-the-line products like CADILLAC NORTHSTAR V-8 32-valve engines. I dont think any one really knows this much detail.
In any case by comparison of the dimension of the power head its bore and stroke one. So to answer my own question posed early on in this story there is no question in my mind that Mercury made-in-China outboard motors are world class. Just like the marine diesels built in China by Caterpillar MTU and John Deere.
With 4100 employees dispersed worldwide Mercury Marines global manufacturing presence stretches from Asia and. Mercury Optimax is also a two stroke as are the NissanTohatsu DFI. How small a motor are you looking at.
There are lots of small two strokes around. Although we have lineup of four strokes we also offer an extensive two stroke lineup to meet diverse global needs. The lineups of outboard models offered differ by country or area.
Product names coloring and graphics may also differ. Mercury engineers leveraged the Mercury Racing heritage to develop this family of high-performance Direct Injected outboards. The result is an outboard family that blows away the competition when it comes to power durability performance and fuel efficiency.
Nothing on the water today is faster or more proven than the OptiMax Pro XS. A Mercury 50 HP outboard motor circa 1980 Six cylinder two-stroke engine in 1984 Mercury Marine is a marine engine division of Brunswick Corporation. Its main product is manufacturing and selling outboard motors.
It also produces the MerCruiser line of sterndrives and inboard motors. Contents 1 History 11 Founding 12 World War II. Yamaha and Mercury have stopped producing direct-injection 2-stroke outboards Tohatsu still builds a few but the latest-generation 4-strokes weigh the same as.
I think with Yamaha it was a business decision. Two-strokes can be made to meet emissions standards to legally sell. However its doubtful outboards 2 stroke or 4 stroke could be made to meet CARB 4-star without a catalytic converter if that were ever imposed on.
Mercury has created a quieter two-stroke in their OptiMax while still maintaining a throaty performance sound. Noise should no longer be a deciding factor in the choice of two vs. While many of the conceived disadvantages of the two stroke outboard have been answered many of the advantages hold true today.
Yes these are two-stroke outboard engines with Evinrude the only manufacturer in this class to stick with injecting oil into the fuel. Traditionally there is a big difference between the two kinds of engines. Two-stroke engines are considered to be more powerful than four-stroke engines while the latter is considered to have a cleaner fuel output.
Mercury Optimax two-stroke engines tend to do better in situations where they dont have to idle too much. This is a 1997 Mercury 15hp 2 stroke outboard motor running in a tank of water in the garden after its yearly service. Id just replaced the impeller low.
Rather than just going with the tried and true Yamaha listened and began to build motors that arent quite so noisy. That being said Yamaha motors still have the reputation of being heavier and heftier. Yamaha currently makes outboard motors that can get anywhere from 25 hp to 425 hp.
This gives it plenty of zip no matter what your needs are.
