The motor features a compact and lightweight design, with a weight of only 312 kg (688 lbs), making it easy to install and maneuver.

The 6H4 also includes a number of convenience features, such as a large, easy-to-read digital display, a built-in fuel gauge, and a conveniently located oil filler cap. The motor's stainless steel propeller shaft and heavy-duty gearcase provide durability and reliability, while the motor's multi-function tiller handle and power trim and tilt system make it easy to adjust the motor's position for optimal performance and maneuverability.

Overall, the Yamaha 6H4-14985-01-00 is a top-of-the-line outboard motor that delivers impressive power, efficiency, and reliability. Whether you're cruising on a large fishing boat or a high-performance ski boat, this motor is sure to meet your needs and exceed your expectations.

Pros:

1. Power and Performance: With a 90 horsepower output, this motor provides excellent power and acceleration, making it suitable for larger boats and more demanding water conditions.

2. Lightweight: At just 172.5 kg (380 lbs), this motor is relatively lightweight for its power output, making it easier to install and maneuver.

3. Fuel Efficiency: Two-stroke engines are known for their fuel efficiency, and the Yamaha F90 is no exception. This can save boat owners money in the long run.

5. Reliability: Yamaha is a well-known and trusted brand in the marine industry, and the F90 motor is no exception. It is known for its durability and reliability.

Cons:

1. Noise Level: Two-stroke engines are known to be louder than their four-stroke counterparts, which can be a drawback for those seeking a quieter boating experience.

2. Maintenance: Two-stroke engines require more frequent oil changes and mixed fuel, which can be more time-consuming and costly than maintaining a four-stroke engine.

3. Emissions: Two-stroke engines produce more pollutants than four-stroke engines, which may be a concern for those seeking a more environmentally-friendly option.

In conclusion, the Yamaha F90 2-stroke outboard motor offers excellent power and performance, lightweight design, fuel efficiency, and versatility.

If you prioritize power, performance, and fuel efficiency, and are willing to deal with the noise and maintenance requirements, then the Yamaha F90 may be the right choice for you. However, if you seek a quieter and more environmentally-friendly option, a four-stroke motor may be a better fit.

In summary, the Yamaha F90 2-stroke outboard motor is a powerful and versatile option for those who prioritize performance and fuel efficiency, but it comes with the drawbacks of higher noise levels, more frequent maintenance, and higher emissions. Ultimately, the decision to purchase this motor depends on the individual's priorities and needs.
