Compact and Light-weight
Yamaha is raising the bar with the introduction of the new F115 four-stroke outboard. The new F115 replaces it superseded model, a brilliant engine that is already the leader in its class. The F115 plays host to all the latest combination of innovative, efficient and performance oriented technology. Featuring a larger, all-new 1832cc, DOHC in-line 4-cylinder engine, this light-weight power plant has been engineered to be the first choice for boaters in the mid horse power category.
Weighing in at a category leading 171kg, the next-generation F115 is 15kg lighter than it supersedes; making it the lightest twin-cam 115HP 4-stroke on the market. The superior refinement of the silky-smooth 4 cylinder design and unmatched power-to-weight ratio, translates to unrivalled fuel economy, reliability and performance. Compact and light weight in design, the F115’s performance and efficiency makes it the ideal choice for boaters looking for the latest technology and innovation to power a new boat, or for boaters who are considering repowering.
1.8 Litre, EFI, DOHC, In-line 4-Cylinder, 16 valve engine
Yamaha is raising the bar with the introduction of the new F115B four-stroke outboard. The new F115B replaces the current F115A, a brilliant engine that is already the leader in its class. The F115B plays host to all the latest combination of innovative, efficient and performance oriented technology.
The engine compression ratio has been increased, and so has the full throttle operating range: 5,300-6,300rpm. The inclusion of an engine knock sensor, which is an uncommon feature in this class of outboard, allows the engine to operate safely and constantly at peak output. Class leading efficiency and performance is achieved throughout the complete rev range via the latest in Yamaha’s efficient multi-point EFI and ECM control and bigger displacement 4-cylinder DOHC (Dual Overhead Camshafts) 4-valve per cylinder design.
The multi-point EFI and ECM control delivers the optimum fuel mixture into the combustion chamber, whilst the DOHC, 4-big-valve, 4-cylinder design guarantees precise, efficient and reliable engine operation.
Previously only seen in larger capacity engines, the all-new F115 sees the introduction of a 5mm offset crankshaft which encourages efficient combustion transfer.
81mm Cylinder Bore
The cylinder bore size has been increased from 79mm to 81mm which provides more engine torque. Larger valves are used to increase both intake and exhaust transfer efficiency.
Multi-Point Electronic Fuel Injection
The ECM controlled multi-point electronic fuel injection system precisely measures the fuel and injects it into the combustion chamber at the optimum timing to increase performance and assure quick engine starting in various environmental conditions.
The four-stroke, four-valve per cylinder F115 is able to maximize combustion efficiency in a way that no two-stroke can, delivering the utmost in quiet power and performance.
60mm Throttle Body
The introduction of a 60mm size single bore throttle body minimises intake resistance and provides first rate response for acceleration and high speed operation.
Best in-class charging power
The F115 alternator delivers more power than before: A full 35 amps at wide open throttle, compared to 24 AMPS on the previous version. At only 1,000 RPM, the F115 alternator produces a full 28 AMPS, which ensures that plenty of power is available for engine starts – even after long periods at low RPM or when using multiple accessories.
Command Link (optional)
All our EFI engines can be linked, via Yamaha’s own digital network system, to a wide range of instruments – to help you get the best from your engine. A multi-function tachometer displays RPM, engine hours, trim angle, oil pressure and warning lamps. The combined Speed and Fuel Management gauge shows speed, fuel tank level and economy data, whilst the inclusion of the YCOP security will give peace of mind protection.
Variable Trolling Speed
Controlled by command link gauges, the operator can adjust the engine’s trolling speed from 600 to 1000 rpm in 50 rpm increments. This helps provide precise and consistent trolling speeds in an array of conditions.
The Variable Trolling feature allows anglers to adjust the boat trolling speed in small speed increments. The ability to fine tune lure presentations to even the fussiest species gives fishermen unprecedented advantages.
Multi-function Tiller Handle (optional)
Yamaha’s award winning Multi-function Tiller Handle offers the benefits demanded most in a tiller control. From its front mounted ignition key switch and gear shift controls, to the easy to use Variable Trolling RPM Switch, it’s ergonomic design provides maximum control with maximum comfort.
Shift Dampener System Propeller (SDS™)
Yamaha’s patent-pending Shift Dampener System (SDS) greatly reduces the noise commonly associated with shifting gears. Using a new design and components specific to Yamaha ‘K’ size propellers, much of the force of shifting is absorbed. Standard on Yamaha’s new K Series aluminium and polished Stainless Steel series of propellers, it means smooth and quiet operation when both shifting and while in gear. These propellers have been engineered for FT60-F130 Outboards and require no special hardware for operation.
