Yamaha F2.5 2024: Compact 2.5HP Four Stroke Power for Small Boats
The 2024 Yamaha F2.5 is a 2.5 horsepower, single-cylinder OHV four stroke portable outboard motor built for small craft duty. With a 72cc displacement, a dry weight starting at just 37 lbs, and shaft lengths of 15″ (S) or 20″ (L), the F2.5 is the smallest engine in the Yamaha portable family — and one of the most popular tender and dinghy motors in the USA. It pairs a dependable manual (recoil) start with a twist-grip tiller, full 360° swivel steering for instant reverse thrust, and Yamaha’s Easy Storage Oil Retention System, which lets you lay the engine down on either side or the front grip without oil leakage. If you need grab-and-go auxiliary power for an inflatable, jon boat, canoe transom, or sailboat, this is the benchmark engine in the 2.5HP outboard class.

Benefits
Four stroke reliability means no premixing fuel, lower noise, and dramatically better fuel economy than old two strokes. The F2.5’s light weight makes it the easiest Yamaha to carry down a dock, stow in a lazarette, or clamp onto a tender in choppy water. Its 360° steering gives you reverse without a reverse gear complication, and Yamaha’s oil retention system removes the biggest headache of storing small outboards in a vehicle or locker.
Applications
Best suited for: inflatable dinghies and tenders, jon boats up to ~10 ft, canoes and square-stern kayaks, small sailboat auxiliary power (choose the 20″ long shaft), duck boats, and marina hop duty. If you regularly carry two or more adults or fight current, step up to the Yamaha F4 2024.
