This Enduro Short Shaft Boat Engine is built for Alaska boaters who need dependable, no-nonsense power for both personal and commercial use. Known for its durability and simplicity, the Enduro series is trusted worldwide in harsh marine environments—making it a strong fit for Alaska’s rivers, lakes, and near-shore waters.

This lightweight two-stroke outboard delivers excellent low-end torque and fast throttle response, ideal for hauling gear, navigating currents, and operating in shallow or remote areas. The short shaft design (15″) is well suited for jon boats, river skiffs, and utility vessels with lower transoms.

With fewer moving parts than four-stroke engines, the Yamaha 40HP Enduro is easier to maintain and repair in remote locations, a key advantage for commercial operators and off-grid users who rely on consistent performance day after day.
