Excerpt: ...engine base is continued to support the reverse gear r, Fig. 1, put in the propeller shaft, put on the stuffingbox and separate stern bearing if one is used, and, if the propeller shaft is to be coupled by means of a sleeve coupling, see that the ends of the shaft project into each end half way, with the key removed, and that the propeller shaft turns freely. If a compression coupling d, Fig. 1, is used, see that both shafts are in line. If the two shafts are flanged, sec that they come fairly together, moving the engine slightly, if necessary, in order to get the shafts absolutely in line, and blocking up the forward or after end of the engine, if necessary, being particular that the propeller shaft does not touch the side of the lead sleeve in the shaft log a, Fig. 1. If a brass sleeve is used, it should not be fastened until the engine is lined up, as stern bearings and stuffingboxes are usually screwed into the brass sleeve. Lead sleeves are usually considerably larger than the shaft; their ends are flanged over and copper-nailed, after being bedded in putty consisting of white lead stiffened to the proper consistency with red lead. Where no sleeves at all or lead sleeves are used, stern bearings and stuffingboxes should be fastened flush with the ends of the shaft log, by means of bronze screws when the stuffingboxes and stern bearings are of bronze, and by means of iron or steel screws when iron stern bearings are to be used. Iron or steel stern bearings should never be used around salt water, except with very large shafts, lignum-Vitw bushed stern bearings and bronze bushings always being used on steel shafts. While bronze lag or coach screws as sent out from the factories are usually employed, a much better custom is to use bronze...
