2027 Yamaha Four Stroke Portable Heavy Load F20LWPB
Description
Meet the 2027 Yamaha F20LWPB Four Stroke portable outboard—a Yamaha Gray workhorse that’s sized to be easy to live with, yet built to push the kinds of hulls that actually get used. This is an engine-only listing (not a complete boat), perfect for repowering a small fishing skiff, tiller/remote utility rig, lightweight pontoon tender setup, or a compact aluminum jon-style hull that appreciates real midrange punch.
At the heart of this F20 is a 432cc, 2-cylinder in-line, SOHC 4-stroke with 4 valves (2 per cylinder). That displacement matters: it helps the 20 bhp (14.9 kW) feel confident when you’ve got extra gear onboard, a second passenger, or you’re pushing into chop. With a 2.00:1 gear ratio turning a propeller, the power is delivered with the kind of “get up and go” that suits small-to-mid lightweight hull classes that need solid torque to climb onto plane and stay there without feeling strained.
Cruise-friendly efficiency is part of the appeal here too. The fuel-injected fourstroke design runs on regular gas, and it’s happiest in its 5000–6000 RPM full-throttle range (rated at 5500 RPM), giving you a practical blend of usable speed and sensible fuel economy when you settle into a comfortable cruise.
Built for real marine conditions, it uses open-loop water cooling and is salt-water capable—ideal for bays, brackish rivers, and coastal inlets. Yamaha also adds peace of mind with a visual/audible engine alert system plus emergency RPM reduction, helping protect your day on the water when conditions (or maintenance schedules) get unpredictable.
This Yamaha F20LWPB features a 20-inch shaft and remote outboard steering control, making it a strong match for many transoms in the “long shaft” class. Starting is flexible with electric start or pull start, and the manual trim system offers 4 trim positions so you can dial in your running angle for load, chop, or shallow approaches. You’ll also appreciate the onboard 16-amp alternator output for supporting basic charging needs while underway.
Dry weight is 146 lbs (66 kg), striking a smart balance between portability and the confident feel of a substantial, heavy-load-capable outboard. If you’re looking for a Yamaha Gray 20-horse fourstroke that’s ready to work, this one is ready to earn its spot on your transom. Warranty coverage varies—contact us and we’ll confirm the applicable Yamaha warranty for this new engine.
