Abstract
The lubrication of a steerable thruster of a marine vessel is based on splash-type lubrication at the pod and full bath lubrication in the stembox and in the shank. The lubrication oil enters the pod both from the stembox and the shank via a constriction and directly from the oil tank. The oil is further circulated from the pod to the oil tank by means of pumps.
