Core Features of Your Yamaha F25SMHC 25 HP Outboard

Class-Leading Power-to-Weight Ratio

The F25SMHC features a redesigned 432cc SOHC In-line 2-cylinder powerhead. This innovative design results in a significantly lighter and more compact engine than its predecessors, making it the lightest 25 horsepower four-stroke outboard available. This substantial weight reduction enhances portability and boat performance, especially for smaller vessels.

Battery-less Electronic Fuel Injection (EFI)

One of the standout features of the F25SMHC is its battery-less EFI system. This cutting-edge technology eliminates the need for a battery to operate the fuel injection, simplifying rigging and reducing overall weight. It ensures effortless starts (even manual pull starts are made easier by an automatic decompression device), smooth idling, cleaner emissions, and optimal fuel efficiency across the entire RPM range, regardless of temperature or altitude.

Manual Start with Easy Decompression

The “M” in the model code signifies manual recoil start. This is ideal for those who prefer simplicity or for applications where a battery might not be practical. Yamaha’s F25 models are designed with an automatic decompression device that requires even less effort for manual starting, ensuring reliable starts with a pull.

Short (15-inch) Shaft

The “S” in F25SMHC indicates a 15-inch short shaft length. This makes it perfectly suited for a wide array of boats with lower transoms, such as many jon boats, canoes, square-stern dinghies, and smaller aluminum fishing boats, ensuring proper propeller depth and optimal performance in shallow conditions.

Multi-Function Tiller Handle

The “H” denotes a multi-function tiller handle. This ergonomic control integrates steering, throttle, and shifting directly at your fingertips. Many Yamaha tiller handles also feature the Variable Trolling RPM Switch (VTS®), allowing you to fine-tune your trolling speed in precise 50 RPM increments, which is highly beneficial for anglers. It also offers wide-angle steering for maximum maneuverability.

High Output Alternator

Equipped with a 16-amp alternator, the F25SMHC generates ample power to keep your boat’s battery charged (if you choose to add one for accessories) and run essential electronics, lights, and other accessories. This ensures you have reliable power for all your onboard needs.

Portable Design with Carry Handles and Resting Pads

The F25SMHC is specifically designed for portability. It features convenient carry handles for easy lifting and transport, as well as built-in resting pads that allow the engine to be stored on its side without oil leakage, simplifying storage in tight spaces.

Durability and Reliability

Built with Yamaha’s renowned quality, the F25SMHC features a robust design. It includes a CDI microcomputer, a wet sump lubrication system, stainless steel drive and prop shafts, YDC-30 aluminum alloy construction, and Yamaha’s Phaze Five™ paint system for superior corrosion resistance. Furthermore, an engine warning system helps monitor vital functions.

Freshwater Flushing Device

A convenient freshwater flushing device is integrated into the engine. This allows you to easily flush salt and debris from the cooling passages without running the engine, greatly extending the lifespan of your outboard, especially after saltwater use.
