1) Why I bought it
When I went searching for a new outboard motor, my primary goal was reliability. Since I plan to use it to pull in and store my boat during cold weather (and a little bit during warm weather), I wanted something that would last through both. Also, since it’s an infrequently used accessory, I didn’t want to spend too much money on it—I didn’t want buyer’s remorse over getting a high-end model. After looking at several options, Yamaha seemed like one of my best bets—it has solid reviews and more power than other models at similar price points.

2) A brief review
Yamaha has been around since 1955 and has been producing quality, affordable engines ever since. They make engines of all sizes, ranging from four to 40-horsepower units. Their four-stroke motors have high power to weight ratios, meaning you can get more performance out of a lighter motor than with comparable two-stroke engines. While their smaller outboards are made for personal watercraft, such as small fishing boats or PWCs (personal watercraft), they also have some larger units with higher horsepower that can be used on larger boats. These larger Yamaha outboards are very popular in both recreational and commercial use.

3) Comparisons with previous models
Most outboards made today are much quieter and more fuel efficient than older models, so you don’t need to change your propeller—they’ll work just fine. That said, certain models come with super-quiet sound suppression technology that cuts decibels even further and can be worth investing in if you plan on spending a lot of time on big water or docking frequently in densely populated areas. The added power on some newer models is also nice if you have a larger boat or one that requires an especially strong push from your motor. More horsepower may not necessarily give you better performance, though; it depends largely on your engine type and hull size.

4) Replacing an older engine
A four-stroke engine is more efficient than a two-stroke and provides more power. This means an increase in top speed and overall maneuverability, both of which can be very important to commercial fishing vessels. On smaller vessels, you’ll notice that gas consumption also drops significantly compared to older 2-stroke engines due to decreased emissions and increased engine efficiency. Finally, it’s much easier to clean these engines because they are self-priming—this saves you time and money down the road when your motor needs maintenance or service.

5) Is it worth it?
There’s a reason that many of us continue to buy Yamaha engines: They make awesome motors. I know, you can save a little money by buying one of those $200 no-name Chinese brands, but do yourself a favor and go with Yamaha. It’s worth it in the long run. You won’t regret it.

6) Where to buy, how much?
Yamaha makes two different outboards in 25 horsepower: The HPDI and VF models. The VF is around $6,000, but it can handle heavier loads and has a greater top speed (44 miles per hour). For that price, you also get four-stroke technology—which is more efficient than its two-stroke competitors. It’s not like there are a lot of other manufacturers making outboards in that class; I mean, Mercury only has 12 hp models on sale. If you want something smaller than 25 hp, Yamaha also makes an eight-horsepower model called the F8B. It has a slightly lower fuel efficiency than its counterpart because it uses an older technology known as carburetion to regulate combustion.

Yamaha’s high-powered portables are redefining the expectations for portable horsepower, from the F15 to the all-new F20 built on the same outstanding platform as the F25, a 2017 IBEX Innovation Award Winner. Their single-overhead-camshaft, two-cylinder designs create power to weight that’s not only eye-opening—but in the case of the F25, it’s also class-leading and category jumping. In fact, the Yamaha’s 25 hp is the lightest 25 on the water—two stroke or four stroke. Like its F15 and F20 siblings, the F25 has signature portable advantages like an oil-retention system for leak-free, on-side storage capability, carry handles and resting pads. So whether you’re headed duck hunting with a jon boat or on the way to a lake cottage and your 14-foot aluminum boat, your Yamahaportable’s ready to go. YAMAHA 25 HP 4 STROKE
