2025 Yamaha Outboards F250
Yamaha brings new levels of convenience and control to a proven performer. The next-generation 4.2-litre F250 Offshore outboard combines a high-performance, big block V6 featuring outstanding power and fuel efficiency with the availability of Yamaha-exclusive built-in Digital Electric Steering and Thrust Enhancing Reverse Exhaust.
Features may include:
SMOOTH, PRECISE DIGITAL ELECTRIC STEERING (DES)- The same smooth, fast, and precise Digital Electric Steering that was introduced on the XTO Offshore is now built-in to F300 and F250 variants. DEC models can be equipped with the new bolt-on Helm Master® EX Digital Electric Steering as well. The result is significantly easier rigging and an uncluttered bilge - with no steering pumps, hoses, hydraulic lines or connections, no bleeding procedure, less complexity and straightforward serviceability. Both use the latest in boat steering technology to provide smooth, fast steering and, unlike some conventional steering systems, draw battery amperage only when actively in use.
- Thrust Enhancing Reverse Exhaust (TERE) keeps exhaust bubbles above the anti-ventilation plate and out of the propeller below 2500 rpm when in reverse. This means the prop bites only clean water, resulting in outstanding reverse thrust and control to back down on fish. It’s especially effective when combined with the fast precision of Digital Electric Steering and the Helm Master EX Full Manoeuvrability joystick – very helpful around docks and confined spaces.
- The new Helm Master EX DEC control brings modern amenities like speed control, trim assist and station selection to all DEC installations, in addition to useful convenience features like single-lever operation and centre engine only to multi-engine DEC applications.
- Yamaha’s exclusive TotalTilt™ function allows complete tilt up from any position with a simple double-push of the “UP” trim/tilt button, or full tilt down (until trim ram contact) by the same double push of the “DOWN” trim/tilt button. For safety, a warning horn will sound just before and during these operations. Movement and the horn can be stopped anywhere in between by pressing the tilt button again. No more holding the trim button makes for effortless trailering and convenience when complete up or down tilt is desired. There’s also a new built-in integrated tilt limiter to help prevent inadvertent damage. Plus, built-in DES models tilt higher out of the water than previous models, which helps lessen the potential for corrosion.
- Optional for boats featuring the new and upgraded V6 Offshore with Helm Master EX Full Manoeuvrability, there is an available Integrated Helm Master Light. The light mounts directly in the rear apron of the outboard(s) rather than requiring independent lights on the transom. These clearly indicate the boat is actively in Full Manoeuvrability mode to anyone approaching from abaft (requires Helm Master EX Prop Light Kit).
- The engine flush hose can now be routed through a new rigging grommet inside the rigging tube, similar to XTO, which means automatic or manual on-board engine flushing systems can be used with ease (requires use of Flushing Kit). This means cleaner rigging and easier operation of one of the most important maintenance procedures for the longevity of the outboard(s). In addition, all V6 Offshore outboards still feature a built-in external flush attachment.
