Abstract (en)
[origin: EP1873374A1] An outboard motor S has: a first drive shaft 31 interlocked with an internal combustion engine, a second drive shaft 32 interlocked with the first drive gear 31, an output gear mechanism 50 driven by the second drive shaft 32, a propeller shaft 17, and a gear case 13 holding the output gear mechanism 50 and the propeller shaft 17 and having a normally submerged gearing holding portion 21. The second drive shaft 32 is disposed rearward of the first drive shaft 31 with respect to a longitudinal direction. The gearing holding portion 21 has a tapered part 21a extending forward from a position corresponding to the second drive shaft 32 and having a front end 21c. The tapered part 21a is tapered toward the front. The disposition of the second drive shaft 32 rearward of the first drive shaft 31 enables forming the gear case 13 in a small size and reduces underwater resistance to the gear case 13.
