Yamaha F8 8HP Outboard Engine FAQs

How heavy is the Yamaha F8? Is it easy to transport?

The Yamaha F8 is designed with portability in mind. It weighs in at approximately 39kg (87 lbs) for the short-shaft model. Its compact, two-cylinder SOHC design makes it one of the lightest in its class, meaning you can easily move it from your car boot to the transom of your tender or small fishing boat without a struggle.

What kind of performance can I expect from the 212cc engine?D

Don't let the "8HP" label fool you; this engine shares the same 212cc displacement as its big brother, the F9.9. This high displacement gives it exceptional torque and "punch" for its size. Thanks to a built-in acceleration pump, you’ll find the throttle response is incredibly crisp, helping your boat get onto the plane smoothly and quickly.

Is the Yamaha F8 noisy?

Not at all. Yamaha has engineered the F8 with a streamlined intake manifold and a high-quality intake silencer. This ensures that air flows directly into the engine with minimal noise, making for a much quieter and more peaceful experience when you're out on the lake or cruising the coast.

What shaft lengths are available, and how do I know which one I need?

We typically stock the F8 in both 15-inch (Short Shaft) and 20-inch (Long Shaft) versions.

• • Short Shaft: Usually best for inflatable tenders and small dinghies.
  • Long Shaft: Ideal for day boats or as a "kicker" / auxiliary engine for larger vessels.

Morgan Marine Tip: If you’re unsure, measure from the top of your boat’s transom to the bottom of the hull. Give us a call if you need help matching this to the engine!

Does it have a charging system for my battery?

Yes! The Yamaha F8 comes equipped with a 6-Amp Alternator. This is a fantastic feature for a portable engine, as it allows you to maintain the charge in your battery to power basic electronics, navigation lights, or fishfinders while you're under way.

How easy is it to steer and control?

The F8 features a newly designed, shorter tiller handle that is much more ergonomic and comfortable to use over long periods. It also features a 43-degree steering angle in both directions, giving you excellent manoeuvrability in tight marinas or when navigating narrow waterways.

What fuel should I use, and is it efficient?

The F8 is a four-stroke engine, so there’s no need to mix oil and petrol—just straight unleaded (minimum 87 octane). It is highly fuel-efficient and meets stringent C.A.R.B. 3-Star ratings for low emissions. We recommend using a Yamaha 10-Micron fuel/water separating filter to keep the fuel system in top shape.

Can I use the F8 in saltwater?

Absolutely. Yamaha engines are built for the marine environment. The F8 features through-propeller exhaust, which helps reduce noise and improves cooling. To protect your investment, we always recommend flushing the engine with fresh water after every use in salt or brackish water—something made very easy by Yamaha's accessible flushing points.

What is the warranty coverage?

When you buy your Yamaha from an authorised dealer like Morgan Marine, you benefit from Yamaha’s legendary reliability. For leisure use, the F8 typically comes with a limited 3-year warranty, providing you with total peace of mind on the water.
