It works similarly to most outboard gearcases, but the trailiing prop is connected to the reverse gear. When it's in Forward, both gears are engaged. In Reverse, only the front prop engages in reverse and the trailing prop just goes along for the ride.

go to a yamaha parts page and look at the gearbox pictures and exploded diagrams for a DX150 (ox66) or D150 (carb) Vmax 150 they use the same gearbox.
