2027 Yamaha Four Stroke In-Line DEC LF150XSA4
Description
Meet the 2027 Yamaha Four Stroke In-Line LF150XSA4 in Yamaha Classic White—a new, engine-only outboard listing built for boaters who want big-water confidence without big-engine bulk. This is Yamaha’s F150 platform: a 2.8L, 4-cylinder, 16-valve DOHC four-stroke that delivers 150 bhp (111.9 kW) at 5500 RPM, right in the sweet spot for many mid-size hulls that need strong, usable punch to get on plane quickly and stay there comfortably.
That 150-horse output pairs beautifully with bay boats, multi-species rigs, center consoles, and family runabouts that live in the “do everything” class—heavy enough to appreciate real torque, but still nimble enough that a responsive outboard makes the day more fun. The 2.00:1 gear ratio helps translate power into confident prop authority, especially when you’re carrying passengers, gear, or a full tank and want crisp acceleration without feeling strained. With a full-throttle range of 5000–6000 RPM, it’s designed to cruise efficiently and still have reserve when conditions change.
Fuel-wise, this outboard keeps ownership practical: it runs on regular gas and uses fuel injection for consistent starts and clean, predictable throttle response. An electric starter and remote steering control make it a natural fit for modern helm setups, while power trim lets you dial in running attitude for changing loads, chop, or speed targets—key for maximizing comfort and fuel economy at cruise.
Built for real marine duty, the LF150XSA4 is salt water capable and uses water (open loop) cooling. Yamaha also adds smart protection with a visual/audible engine alert system and emergency RPM reduction, helping you respond quickly if something needs attention.
This is a 25-inch shaft model and comes in at a 522 lb dry weight, a solid match for transoms designed around modern 150-class power. Need rigging flexibility? It’s also counter rotating capable, giving you options for multi-engine installations and handling balance.
Ask us about warranty coverage available on this new Yamaha outboard and how this Classic White F150 can be the perfect repower—or the perfect start—for your next build.
