A marine engine propelling apparatus (10) is mounted to an outboard portion at a rear end of a boat. The engine propelling apparatus (10) has a power generating portion (13), a power transmitting portion (17) provided below the power generating portion (13), a propelling force generating portion (28) provided below the power transmitting portion (17), and a height adjustment mechanism (25). The power generating portion (13) includes an engine (11) equipped with a crankshaft (11C), and the crankshaft (11C) is arranged substantially parallel to a front-rear direction of the boat and is substantially horizontal. The power transmitting portion (17) has a power transmission mechanism forming a linear power transmission route (D2) extending from the vicinity of a front end of the crankshaft (11C) to the vicinity of a front end of the propelling force generating portion (28). The propelling force generating portion (28) includes a propeller shaft (22) extending rearwards from the power transmitting portion (17), and a propeller (27) provided at a rear portion of the propeller shaft (22). The height adjustment mechanism (25) is configured to vary inclination of a part of the propeller shaft (22) with respect to the boat to thereby vary height of the propeller (27) with respect to the boat. |
