Abstract: A drive train in a marine vessel includes a marine pod drive unit and an inboard engine operatively connected by a driveshaft. To protectively enclose the driveshaft, a guard sleeve having a tubular configuration is disposed around the driveshaft and extends between the marine pod drive unit and the inboard engine. The first sleeve end of the guard sleeve is coupled to a first coupling collar on the marine pod drive unit using a first annular packing and the second sleeve end is coupled to a second coupling collar on the inboard engine using a second annular packing. The first and second annular packings enable relative angular displacement between the guard sleeve and the marine pod drive unit or the inboard engine.

Abstract: An example of controlling a marine vessel is described herein. Some examples involve receiving an input to place a drive system of a marine vessel into an operation mode; positioning, by the device, two or more marine drive units of the drive system in a first configuration based on the input; identifying, by the device and while the drive system is in the operation mode, that respective throttles associated with the two or more marine drive units are in a same drive position; and repositioning, by the device, the two or more marine drive units to a second configuration based on identifying that the respective throttles are in the same drive position.
