SERIES 'A'
This sterntube assembly is used where the propeller shaft overall length is such that it requires intermediate bearing and distance between the dead and FWD face of the rudder is less, due to this outer bearing gland is not possible to use. It includes outer bearing a bronze tube & water lubricated gland assembly with half bearing.

SERIES 'B'
This sterntube assembly is used where the engine is flexibly mounted, so there is no use of intermediate bearing and the distance between the deadwood and forward face of the rudder prohibits the use of outer bearing. It includes a outer bearing, a bronze tube and a flexible inboard gland assembly. The bearing is lubricated by water, usually supplied from the engine cooling system.
