A reverse gear for watercrafts includes an input shaft that receives rotational power of a main engine. A forward/reverse switching mechanism includes a reduction function and switches the rotational power of the input shaft among forward, neutral, and reverse states. An output shaft outputs the rotational power of the forward/reverse switching mechanism and rotates at a rotational speed that differs from a rotational speed of the input shaft due to the reduction function of the forward/reverse switching mechanism. A reduction mechanism includes a fixed reduction ratio, and reduces the rotational power of the output shaft and transmits the reduced rotational power to a propeller shaft. A forward/reverse housing accommodates the forward/reverse switching mechanism. A reduction housing accommodates the reduction mechanism. The forward/reverse housing and the reduction housing are detachably coupled one behind the other in an axial direction of the output shaft.
