Yamaha F25SC 25HP Outboard – 15in Shaft, Electric Start

Description

Short-transom fiberglass runabouts achieve exceptional low-end acceleration when the Yamaha F25SC translates its 432cc displacement into instant thrust. The advanced Electronic Fuel Injection system meters gas precisely, pushing heavy aluminum side-consoles across choppy morning bays without carburetor hesitation. A quick tape measure check validates this 15 inch shaft remote steer outboard mounts safely without generating excessive hydrodynamic drag below the hull.

Execute flawless dock approaches in heavy crosswinds by leveraging the remote mechanical steering bracketry for precise directional control. You pilot fast coastal runabouts securely from a forward helm without relying on awkward tiller extensions. Engineers build the 58 kg assembly using specialized marine-grade aluminum alloys. This thick-wall casting survives submerged log strikes when repowering coastal utility boats for daily saltwater exposure.

Key Features of Yamaha F25SC

• Electronic Fuel Injection: Vaporizes gas instantly into the cylinders regardless of temperature, guaranteeing crisp throttle translation on lightweight fiberglass hulls.
• 15-Inch Short Shaft: Matches standard low transoms exactly, preventing excessive drag from a deep gearcase and increasing top-end speeds drastically.
• Remote Steering Bracketry: Accepts standard mechanical cables directly from your forward helm, integrating flawlessly for precise directional control on console dinghies.
• Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating physical pull strain completely during freezing early morning launches.
• 16-Amp Charging Alternator: Keeps your cranking battery topped off automatically, powering demanding fish finders and livewell pumps reliably all day.
• Manual Tilt Bracket: Adjusts the running angle physically, allowing the operator to lift the gearcase over shallow coastal reefs safely.
• 432cc Displacement Block: Produces massive low-end torque internally, lifting heavily loaded 14-foot rigid dinghies onto plane much faster.
• 2.08:1 Gearcase Ratio: Multiplies engine torque effectively, translating the 432cc displacement into relentless pushing force for loaded hunting skiffs.
• Impact-Deflecting Geometries: Reinforces the lower unit housing tightly, protecting internal gears against hidden submerged log strikes in shallow water.
• Four-Stroke Engineering: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.

Why Choose Yamaha F25SC

This exact model demands a 15-inch transom height paired with a complete forward helm station. Attaching it to a 20-inch transom leaves the cooling intakes completely dry. Tiller conversion requires extensive factory retrofits. Finding a low transom remote outboard fits specific classic sport hulls perfectly.

• Confirm your transom measures exactly 15 inches vertically down the centerline.
• Route mechanical steering and shift cables cleanly avoiding sharp pinch points.
• Operate legally on restricted waters using certified low-emission combustion processes.

Ideal Application and Vessel Fitment

Engineered for low-profile fiberglass micro-skiffs, classic aluminum bass trackers, and lightweight sport boats equipped with forward consoles, this 432cc block provides oversized displacement torque. Because the shaft length perfectly matches standard 15-inch transoms, the gearcase generates minimal hydrodynamic drag, maximizing top-end speed on ultra-light hulls. By utilizing the factory remote controls, operators navigating a shallow water remote steer outboard can maintain perfect forward visibility while flying across coastal bays.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Pleasure Warranty alongside exceptional factory support. Registered commercial applications fall under a strict 1-Year Commercial Warranty with separate terms applied to the block. Scheduled maintenance requires replacing gearcase lubricants and changing oil filters at manual-specified intervals. Always save all physical service records. Your engine serial number acts as the only way to source exact genuine replacement parts. Mulmotor provides pre-purchase product guidance and order-related customer support.
