Why the Yamaha F25SWTHC Stands Out: Power Trim & Tilt in a Portable Package

For boaters who demand effortless control and maximum convenience from a portable outboard, the Yamaha F25SWTHC, in fact, excels as a premium option. Primarily, its signature feature is the inclusion of Power Trim & Tilt (PTT). This allows you to effortlessly adjust the engine’s angle to optimize performance, run in shallow water, or fully tilt the motor out of the water with a simple push of a button on the tiller handle. This is a significant upgrade from manual tilt models, offering unparalleled ease of use and versatility.

Moreover, the “SWTHC” in its designation clearly spells out its key characteristics:

• S: Short Shaft (typically 15 inches)
• W: Electric Start with Manual Backup
• T: Power Trim & Tilt
• H: Tiller Handle Control
• C: (Often refers to a specific design or control type, though for this model, the T is the dominant feature differentiating it from the F25SWHC)

Despite incorporating PTT, the F25SWTHC maintains a remarkably low weight (approximately 146 lbs / 66 kg). While slightly heavier than manual tilt versions due to the PTT mechanism, it remains one of the lightest 25-horsepower outboards with this feature, making it genuinely easy to carry, mount, and store.

A key innovation shared across the F25 line is its battery-less Electronic Fuel Injection (EFI) system. This provides, for instance, exceptionally smooth and easy starts (even without a battery), optimizes fuel atomization for maximum efficiency, and ensures crisp throttle response across the RPM range.

Beyond that, the F25SWTHC features a powerful 16-amp high-output alternator, ensuring ample power for onboard electronics like fishfinders, GPS, and lights, even during extended periods of idling. Naturally, like all Yamaha outboards, it benefits from extensive corrosion prevention measures, including proprietary alloys and multi-layered paint finishes. This guarantees long-term durability in both freshwater and saltwater environments. Therefore, the F25SWTHC consistently delivers lightweight, efficient, and robust performance, now with the added convenience of power trim and tilt, making it an outstanding choice for any boater seeking a versatile and dependable portable outboard.

Core Features of Your Yamaha F25SWTHC 25 HP Four-Stroke Outboard

Power Trim & Tilt (PTT)

The “T” in F25SWTHC signifies its Power Trim & Tilt system. This provides, for instance, effortless, push-button control over the engine’s trim angle for optimal performance, and full tilt-up capability for shallow water navigation, trailering, or storage. This is a significant convenience feature, especially on heavier boats or when needing frequent trim adjustments.

Electric Start with Manual Backup

The “WH” indicates electric start with a manual backup pull-start. This provides, for instance, the convenience of push-button ignition for effortless starts, coupled with the security of a manual option should your battery run low or fail, ensuring you’re never left stranded.

Short (15-inch) Shaft

The “S” in F25SWTHC signifies a 15-inch (Short Shaft) length. This makes it ideal for transoms typically found on smaller aluminum boats, inflatables, and some utility boats, ensuring proper propeller depth.

Tiller Handle Control with VTS®

The “H” denotes a tiller handle control. This provides direct, intuitive steering and throttle control. Furthermore, it includes the Variable Trolling RPM Switch (VTS®), allowing you to fine-tune trolling speeds in precise 50-RPM increments (typically from 750 to 1050 RPM) directly from the tiller. This is highly beneficial for various fishing techniques.

25 Horsepower (Prop Shaft)

Delivering a robust 25 horsepower at the prop shaft, the F25SWTHC provides ample power. As a result, it offers brisk acceleration and efficient cruising for a wide range of smaller boats, including aluminum fishing boats, inflatables, and tenders.

Lightweight & Compact Design

Despite the added PTT, the F25SWTHC is engineered for class-leading lightness (approx. 146 lbs / 66 kg). This makes it one of the lightest 25 HP outboards with power trim and tilt available, significantly easier to carry, transport, and mount on your transom.

Battery-Less Electronic Fuel Injection (EFI)

A groundbreaking feature, the battery-less EFI system ensures instantaneous, reliable starting with less effort and provides optimized fuel efficiency across the entire RPM range, even without the need for a separate onboard battery.

Smooth 432cc In-Line 2 Engine

The F25SWTHC features a smooth and refined 432cc, 2-cylinder, SOHC (Single Overhead Camshaft) engine. This design, for instance, ensures consistent power delivery with minimal noise and vibration.

High-Output Alternator (16 Amps)

Equipped with a powerful 16-amp alternator, the F25SWTHC generates ample power. Consequently, this helps reliably run your boat’s lights, fishfinders, GPS, and other small electronics, even during extended idling.

Freshwater Flushing Device

A convenient Freshwater Flush Device is integrated into the engine. This allows you to easily flush salt and debris from the cooling passages without running the engine. Consequently, this significantly extends your outboard’s lifespan, especially after saltwater use, making maintenance simple.

Legendary Yamaha Reliability and Corrosion Protection

Yamaha built the F25SWTHC with legendary quality. It features a robust design, including a CDI Microcomputer ignition and superior corrosion protection (YDC-30 alloy, 5-stage paint). Yamaha engineers designed it to withstand rigorous marine environments, providing years of trouble-free operation.

CARB 3-Star Rating

The F25SWTHC holds a 3-Star C.A.R.B. (California Air Resources Board) rating. This, in turn, indicates ultra-low emissions, making it an environmentally conscious choice for discerning boaters.

Perfect Applications for Your Yamaha F25SWTHC 25 HP Outboard

The Yamaha F25SWTHC is an incredibly versatile and powerful choice for a variety of smaller recreational and utility boats that benefit from power trim and tilt:

• Smaller Aluminum Fishing Boats (e.g., Jon Boats, Small V-Hull Fishers): Indeed, it’s an excellent match for inshore and lake fishing, providing ample power for reaching spots, precise trim for varying loads and water conditions, and reliable trolling control. The short shaft is perfect for many smaller aluminum transoms.
• Inflatable Boats and RIBs (Rigid Inflatable Boats): Furthermore, its light weight, combined with the convenience of electric start and PTT, makes it ideal for powering inflatables where ease of launching, retrieving, and shallow water access are paramount.
• Small Fiberglass Utility Boats and Skiffs: Moreover, it’s well-suited for smaller fiberglass skiffs and utility runabouts used for general recreation, lake cruising, or light work, offering a blend of performance, portability, and sophisticated trim control.
• Tenders for Larger Vessels: Crucially, its compact size, PTT for easy lifting, and full features make it an excellent tender for larger boats.
