Yamaha F4LMHA – 4HP Long Shaft Portable Outboard Motor For Sale

The 4 HP outboard motor Yamaha (F4LMHA) brings the reliable 4 HP 4-stroke performance of Yamaha’s portable series to a 20″ long shaft configuration — the ideal choice for standard-height transoms, fiberglass tenders, and displacement hulls that require deeper propeller submersion for efficient, smooth, aeration-free thrust. At 61 lbs, this 4 HP Yamaha outboard motor for sale strikes the perfect balance between genuine portability and sufficient pushing power for a wide range of small watercraft, making it one of the most versatile entries in the Yamaha portable lineup.

Yamaha rates the F4LMHA at 4 horsepower at 4500 RPM — a slightly lower peak RPM than the short-shaft F4SMHA, delivering a smoother, lower-rev power curve that suits displacement hull operation and fuel-conscious cruising at trolling speeds. The 20″ shaft ensures the propeller stays properly submerged even when the transom lifts slightly at speed, preventing surface aeration and maintaining consistent, predictable thrust. For sailors outfitting a fiberglass dinghy or boaters with mid-height transoms, the F4LMHA eliminates the prop-out-of-water problem that plagues short-shaft engines on higher-sided boats.

Whether you’re outfitting a sailboat dinghy, a fiberglass tender, or a pontoon-style inflatable with a 20″ transom, the F4LMHA is one of the most versatile Yamaha portable outboard motors for sale in our New York inventory.
