Document Type and Number:
Japanese Patent JP2016142238
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve operability of a hull by sufficiently securing a steering angle in turning when a plurality of outboard motors are disposed in parallel on the hull, and improve turning performance of the hull by securing thrust of the outer outboard motor in turning.SOLUTION: A left bank of an engine 11 is provided with a left exhaust passage 41 communicated to an exhaust port disposed on the left bank and including a catalyst converter 53 inside, at an outer side in an outboard motor width direction with respect to a cylinder, and a right bank of the engine 11 is provided with a right exhaust passage 42 communicated to an exhaust port disposed on the right bank and including a catalyst converter 53 inside, at an outer side in the outboard motor width direction with respect to the cylinder. A drive shaft 22 for transmitting driving force from the engine 11 disposed at an upper portion to a propeller 25 disposed at a lower portion, is vertically disposed on an outboard motor main body 10A, and central positions O of the left exhaust passage and the right exhaust passage are located at a front part with respect to the drive shaft 22 in a longitudinal direction of the outboard motor.SELECTED DRAWING: Figure 4
