Abstract
The drive transfers power from an engine driven drive shaft to a propeller shaft, through the hull (not the stern) of a boat. The power is transferred by a chain and sprockets which are fully enclosed and lubricated by oil inside the drive. The tension in the chain is adjustable without disassembling the drive. The propeller shaft is carried on bearings in the main housing of the drive which is made up of a top plate, a streamlined hollow strut and the propeller shaft pod. The drive shaft is carried in a sub housing made up of top and bottom halves. The chain is installed before the top half of the sub housing and the bearings for the drive shaft are installed. This method allows for the slack and clearance (sidewise from the chain) for connecting the ends of the chain together. When the drive is fully assembled, the gap between the main and sub housing is mechanically adjustable to adjust chain tension. A sealing system seals the variable width gap to retain the oil in the drive.
