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.
