Abstract
An outboard drive includes a prime mover having an output shaft. A driveshaft is coupled with the output shaft. Both shafts having axes that extend at least generally parallel to each other. A propulsion device is coupled with the driveshaft. The prime mover rotates the output shaft to drive the propulsion device through the driveshaft. A speed change mechanism is positioned between the output shaft and the driveshaft. The speed change mechanism changes a rotational speed of the output shaft transmitted to the driveshaft.
