Boat owners considering purchasing a new outboard motor often have questions about the difference between a two-stroke and four-stroke outboard motor. Many people immediately assume that a two-stroke is less powerful an therefore, less desirable. This isn’t necessarily true. On this Tip of the Week, Bill delves into the history two- stroke marine engines, and the differences between two- and four- stroke engines. Outboard stroke vs stroke - fuel consumption.
Specializing in used stroke outboards and stroke outboard boat motors. A stroke works great for me cruising under 4k rpm getting 5mpg. If I really feel like lolly gagin’ I can stretch it to 6mpg. That being sai 2-stroke engines are more powerful.
As time has gone by the simplicity of these motors has diminished as the technology advanced. ADVANTAGES OF STROKE ENGINE :-More torque :-In general, stroke engines always make extra torque than stroke engine at low RPM. Although stroked ones give higher torque at higher RPM but it has a lot to do with fuel efficiency.
I figured I would post this question in this topic due to its not a brand specific question. I echo the posts above in terms of “depends of where you ride”. Stroke vs Stroke Engine. With the old motor, no problem getting over plane and running about mph Im wondering about the power rating of new motors. Fifty horsepower will accelerate a boat of X weight at N rate, utterly regardless of whether those fifty horses came out of a two- stroke or a four- stroke.
In the past, stroke engines suffered from terrible fuel economy and were known for spewing exhaust and pollution. Each have several different main features, for example two stoke outboards are lighter, faster (in some cases) and less expensive. Four stroke motors are cleaner, smoother, more economical, great trolling motors and meet environmental requirements. Whether you are looking at a new boat and motor or you are looking to freshen your old boat up for the Spring fishing season with a new motor, choosing the right design is important.

Will l notice any difference in the power? In this post I am going to tell you about the difference between two stroke and four stroke engines. A few years ago, we did a lot of two- stroke versus - stroke theme stories.
No matter what two bikes you choose, too may things were different to make it a legitimate comparison. Now we have two bikes that are ideal for that challenge. A third set of tests compared a 135-hp, two-cycle DFI outboard against a 130-hp, four-cycle outboard on identical 20′ boats. Best economy for the two-cycle was achieved at 27. Soon, the diesel engine maker Oxe from Sweden will release a 2. L turbo diesel four- stroke outboard motor capable of 200hp.
According to Oxe, it will use less fuel compared to two- stroke engines. The two-cycle delivered 4. HP models of Honda ( hp) and Tohatsu ( hp). Two stroke Engine: In this engine the cycle is completed in strokes of the piston or in one revolution of crankshaft.
In strokes, Instead of valve ports are used for suction and exhaust purpose. As the moving parts are less the mechanical effi.
