PROBLEM TO BE SOLVED: To provide a speed change mechanism capable of miniaturizing and also obtaining free speed change ratios in a marine propelling apparatus having a prime mover, a marine gear and speed change gear. SOLUTION: In the marine propelling apparatus having the prime mover 1, the marine gear 20 and the speed change gear 3, the marine gear 20 is provided with a forward and reverse clutch, and the speed change gear 3 is arranged between the prime mover 1 and the forward and reverse clutch. A clutch shaft mechanism is arranged in an outer periphery of an input shaft 37 to the speed change gear 3, and arranged numbers of the clutch shaft mechanism are more than numbers of speed change. The aforementioned clutch shaft mechanism having the same speed change ratio is disposed to the position of a point of symmetry or the position closer to the point of symmetry against the aforementioned input shaft 37.
