EFFECTIVE January 15, 2021YAMAHA MARINE ENGINE SYSTEMS HOT SHEETV6 OFFSHOREDEC MODELUpdated Yamaha V6 OffshoreCombines New Benefits withReliable Performance LegacyBuilt-in Digital Electric Steering (DES), ThrustEnhancing Reverse Exhaust (TERE) and otherXTO-inspired features now available on F250and F300 DEC models*When Yamaha asked customers how to improve uponthe Yamaha V6 Offshore, they responded: “Don’t changethe basic design.” Why would we, when over 97 percent**of Yamaha 4.2-liter V6 Offshore models sold since 2014have never had a warranty claim? Customers also gaveYamaha some great ideas for how to make the reliableplatform even better. The result is the most feature-richV6 outboard Yamaha has ever produced. Yamaha hasupdated its F300 and F250 4.2-liter V6 Offshoreoutboards with benefits previously only available on itsflagship model, the XTO Offshore . Combining a highperformance, big block V6 featuring outstanding powerand fuel efficiency with the availability of built-in DigitalElectric Steering and a Thrust Enhancing Reverse Exhaustsystem (both Yamaha exclusives), Yamaha brings newlevels of convenience and control to a proven performer.*Mechanical F225, F250, and F300 models remain unchanged. **Refers to analysis of warrantyclaim data for powerhead, lower unit, and/or trim/tilt unit only on subject outboards. This datawas collected between January 1, 2014 and November 9, 2020, and incorporates outboards that arestill covered under warranty and which may generate additional warranty claims prior to warrantyexpiration. Except as explicitly stated in a product’s factory limited warranty statement or extendedservice contract, Yamaha Motor Corporation, U.S.A. makes no warranty of any kind, expressedor implied, including, but not limited to, implied warranties of merchantability and fitness for aparticular purpose, for such product.1The new V6 Offshore DECmodel is a product of Yamaha’sCommandBlue philosophy.TMCommandBlue representsYamaha’s commitment to moveengineering development intothe realm of the customer,ultimately delivering productsthat are easier to use andcreate greater satisfactionand confidence on the water.

V6 OFFSHORE DEC MODELYAMAHA MARINEENGINE SYSTEMSHOT SHEETSMOOTH, PRECISE DIGITAL ELECTRIC STEERING (DES)The same smooth, fast, and precise Digital Electric Steering that was introduced on the XTO Offshoreis now built-in to F300 and F250 variants. DEC models can be equipped with the new bolt-onHelm Master EX Digital Electric Steering as well. The result is significantly easier rigging and anuncluttered bilge - with no steering pumps, hoses, hydraulic lines or connections, no bleedingprocedure, less complexity and straightforward serviceability. Both use the latest in boat steeringtechnology to provide smooth, fast steering and, unlike some conventional steering systems,draw battery amperage only when actively in use.32 *32 *Built-in Digital Electric Steering (DES)Bolt-on Digital Electric Steering (DES)*Maximum available steering angle (does not account for possible physical obstruction).2

V6 OFFSHORE DEC MODELYAMAHA MARINEENGINE SYSTEMSHOT SHEETMORE CONVENIENCE AND CONTROLLittle things make big differences, and the new, upgraded 4.2-liter V6 Offshore has them.NEW BENEFITS INCLUDE: Stronger reverse and low-speed maneuvering – Thrust Enhancing Reverse Exhaust (TERE)keeps exhaust bubbles above the anti-ventilation plate and out of the propeller below 2500 rpmwhen in reverse. This means the prop bites only clean water, resulting in outstanding reversethrust and control to back down on fish. It’s especially effective when combined withthe fast precision of Digital Electric Steering and the Helm Master EX Full Maneuverabilityjoystick – very helpful around docks and confined spaces.: Exhaust: Water3

ilt-up functionV6 OFFSHORE DEC MODEL YAMAHA MARINEENGINE SYSTEMSHOT SHEETMore flexibility, more control – The new Helm Master EXDEC control brings modern amenities like speed control,trim assist and station selection to all DEC installations,in addition to useful convenience features like singlelever operation and center engine only to multi-engineDEC applications. Through easy-to-add Helm Master EXupgrades, boats can be equipped with Yamaha AutoPilotand even a Full Maneuverability Joystick. That includessingle outboard boats!*Smoother ride – Borrowed from the XTO Offshore, thelower motor mounts are larger and softer for lessvibration while properly harnessing motor movement.Faster, easier engine tilting– Yamaha’s exclusive TotalTilt function allows complete tilt upfrom any position with a simpledouble-push of the “UP” trim/tiltbutton, or full tilt down (until trimram contact) by the same doublepush of the “DOWN” trim/tiltbutton. For safety, a warning hornwill sound just before and duringthese operations. Movementand the horn can be stoppedanywhere in between bypressing the tilt button again.No more holding the trim buttonmakes for effortless trailering andconvenience when complete up or down tilt isdesired. There’s also a new built-in integrated tiltlimiter to help prevent inadvertent damage. Plus,built-in DES models tilt higher out of the waterthan previous models, which helps lessen thepotential for corrosion.Auto UpTilt rangeAuto DownTilt rangeManualTrim range*All mobility, AutoPilot, and SetPoint positioning functions work well in single-outboard Helm Master EX applications, exceptStayPoint and lateral operation resulting from direct input via the joystick, which do not function.4

V6 OFFSHORE DEC MODEL YAMAHA MARINEENGINE SYSTEMSHOT SHEETClean rigging – Optional for boats featuring the new and upgraded V6 Offshore withHelm Master EX Full Maneuverability, there is an available Integrated Helm Master Light. Thelight mounts directly in the rear apron of the outboard(s) rather than requiring independentlights on the transom. These clearly indicate the boat is actively in Full Maneuverability mode toanyone approaching from abaft (requires Helm Master EX Prop Light Kit, p/n 6KA-762A0-00-8Dfor gray V6 Offshore models, p/n 6KA-762A0-00-CE for white V6 Offshore models). Easier flushing – The engine flush hose can now be routed through a newrigging grommet inside the rigging tube, similar to XTO, whichmeans automatic or manual on-board engine flushingsystems can be used with ease (requires use ofFlushing Kit, p/n 6KA-762Y0-00). This meansBoat-mounted FlushingConnection/Manifoldcleaner rigging and easier operation of oneof the most important maintenanceprocedures for the longevity of theoutboard(s). In addition, all V6 Offshore Wateroutboards still feature a built-inexternalflush attachment.There’s05 F300F Enginemount prop.light (optional)even a new side exhaust cover to helpprevent inadvertent paint discolorationwithout sacrificing performance.5to cylinderwater jacketto cylinderwater jacket

V6 OFFSHORE DEC MODELYAMAHA MARINEENGINE SYSTEMSHOT SHEETINCREDIBLE POWER AND PERFORMANCEAs the only outboard manufacturer using a highly advanced, thermally applied plasma fusion processon the cylinder walls, Yamaha’s V6 Offshore outboards have no conventional steel cylinder sleeves,yet the cylinder walls are 60 percent harder than steel. That means larger cylinder bores for increaseddisplacement result in more power and torque without increasing outer cylinder dimensions. It alsoresults in significantly lighter weight, better cooling and “micro-textured” cylinder walls thatdramatically reduce internal friction loss, further increase performance and enhance reliability.OUTSTANDING FUEL ECONOMYAll air entering the engine block of each Yamaha V6 Offshore outboard is routed through a single75mm electronically-controlled throttle valve. Working in concert with the Precision Multi-Point FuelInjection System, these features help ensure the precise amount of air and fuel necessary for optimumpower and fuel efficiency. The reduction in friction from the micro-textured cylinder walls further addsto this outboard’s amazing fuel economy.8

V6 OFFSHORE DEC MODELYAMAHA MARINEENGINE SYSTEMSHOT SHEETMOUNTING BRACKETThe mounting bracket and dimensions for models featuring built-in DES are shown below. Pleasenote that built-in DEC models are mounted to the transom with six bolts, like Yamaha’s XTO Offshore,as the powerhead is mounted 71mm higher than standard bracket models. This provides the additionalheight needed for the built-in DES, and the ability to use these models in most flat-transomapplications. DEC models without built-in DES (for use with optional bolt-on DES) and mechanicallycontrolled models have no bracket changes from current 4.2-liter V6 Offshore models.9
