Suzuki 4 Stroke Outboard VS Yamaha – Comparison 2021

Suzuki 4 Stroke Outboard VS Yamaha

Gone are those days where Yamaha was the only reliable outboard engine manufacturing company. During the last decade, noticeable numbers of outboard engine manufacturers introduced their engines in the market, which were technologically advanced, powerful, and reliable as well.

Suzuki outboard engines come next to Yamaha. Their engines are proving the performance, durability, ability to withstand the harshest condition, as well as reliability among the commercial outboard businesses as well as individuals.

If you are to buy a four-stroke engine for your outboard, you must compare Suzuki 4 stroke outboard vs Yamaha to make the investment worth.

What Is Outboard?

Outboards are a more advanced form of conventional boats. They run super-fast even in the ocean, which is something you cannot achieve in typical boats. An outboard has a high HP engine, jet drive, gearbox, as well as advance and well-decorated interior.

People mostly use outboards for recreational purposes such as catching fish, traveling in the ocean, and more. If you love the ocean and find peace spending time near beaches, an outboard journey will take your experience to a whole new level.

Outboards are expensive, so are engines. However, you can still manage to enjoy the sea-ride by renting an outboard from coastal areas. There are lots of commercial outboard businesses that rent boards for a few hours to days.

Is Suzuki and Yamaha Trustable?

Let’s talk about Yamaha first. Yamaha has been selling outboard engines for over 30 years. Their engines are of top-class compared to others available in the market. Among the customers,

Yamaha motors have a good reputation for performance, reliability, and enhancing the sea-riding experience.

Although Suzuki marine is manufacturing outboard engines for the last 50 years, they are not as popular as Yamaha. For a few decades, their top-grade engines managed to grab peoples’ interest. The performance of their motors is pretty much comparable with Yamaha, which tells you the reliability of Suzuki.

So, yes, if you are concerned about their trustworthiness, you can rely on both the brands.

Suzuki 4 Stroke Outboard Vs Yamaha

People are well aware of Yamaha. Suzuki, on the other hand, doesn’t have that number of die-heart fans, which can be the reason why people don’t know much about Suzuki outboard motors.

Let’s put Suzuki and Yamaha head to head and see which one dominates the most regarding some key aspects of an outboard engine.


The performance of an outboard will determine how well it maintains the speed in various oceanic conditions. A good performing engine requires to adjust its throttle quite less.

Considering Yamaha, their four stroke engines are performance beasts. There is no denying the fact that, when it comes to performance, engines of other bands will have a tough time to fight head to head with Yamaha.

Four-stroke engines from Yamaha can handle big waves consistently while giving you a stable boating experience. Regarding the WOT speed, most Yamaha engines can provide you with 37 knots in calm water.

As far as the performance of Suzuki marine engines is concerned, they also can maintain a decent speed to handle various ocean conditions. The engines are efficient enough and don’t require to adjust the throttle more often.

Where Yamaha engines deliver 37 knots, Suzuki marine motors are able to take it up to 40. So, even though Yamaha is the topmost outboard engine manufacturer, Suzuki is the winner here.


When you run the engine at about 3500 rpm, Yamaha will make noticeable noise as most engines do. As you increase the rpm, the engine will make even louder noise. At idle condition, Yamaha makes noise to some extent as well.

So, overall, whether running at high rpm or leaving at idle state, it’s a noisy engine for sure. Noise is where Suzuki dominates the most. The engines of Suzuki marine make relatively less noise compared to Yamaha as well as other reputed brands.

People who rent outboard for spending recreational times, they don’t even notice that the engine is still active at idle state. If you are looking for an outboard motor for commercial purposes, your clients will be impressed with the Suzuki engine regarding the noise issue for sure.

Vibration on both the engine at idle and low revs are quite identical. However, if you are too sensitive to vibration, Suzuki will feel less vibrating to you.

Fuel Economy

When it’s about oil consumption, Yamaha isn’t a good choice. The powerful engines from Yamaha aren’t efficient regarding the oil factor. If you run the engine at 3000 rpm, it will consume about 27.7 liters per hour. When the engine runs at 4000rpm, it will require 30.5 liters per hour.

Compared to Yamaha, Suzuki comes out very impressive at fuel consumption. If you run a Suzuki engine that is similar to the configuration of Yamaha, it will only consume 18.9 liters per hour while running at 3000rpm.

Furthermore, at 4000 RPM, the engine will require 25.91 liters per hour, which is quite less than what a Yamaha engine consumes. However, considering Wide Open Throttle, Yamaha takes the lead here; it almost takes 5 liters less than Suzuki. There will be no noticeable smoke or fumes from both engines.

Machine and Accessories Availability

You will find a number of dealers for Yamaha engines in your area. If you need any type of machinery, supplies, or accessories for the engine, it will not take much effort to get. Yammie engine parts are widely available in most coaster areas.

Things are not favorable when you will need some parts or machinery for a Suzuki engine. These are not available like Yamaha. Only popular models are found, but there’s no assurance that you will certainly find the desired part.

So, here for Suzuki engines, you will rely on e-commerce websites for getting supplies, which is time-consuming and less reliable than getting from stores.

Ease of Use

Operating Suzuki engines feel less clunky than its close competitor. Also, the tilt hydraulic system runs relatively quieter than Yammie.

Due to innovative fuel data and engine systems, you will be able to operate both the engines very accurately. However, there is no hour counter gauge with Suzuki engines. The tacho will provide a rough calculation of usage.

You can connect both Yamaha and Suzuki marine engines to marine electronic units using NMEA 2000. But, if you are to connect a Suzuki engine to a GPS for accessing NMEA data, it will not be an easy task. Plus, the plugs are hard to find.

Final Words

Being an underdog, Suzuki beats Yamaha in various aspects. Performance, smoothness, quietness, and ease of use make Suzuki marine engines very appealing to get.

Hopefully, you are no longer confused between Suzuki 4 stroke outboard vs Yamaha engine and have already decided which one to pursue.
