propeller shaft lubrication OLD Maramu 1989 #261

There are 3 hoses attached to the propeller shaft, one hose has a greese container with a T handle to turn and force the grease into (or around) the shaft. What kind and grade of grease should be refilled. Also the other 2 hoses are connected to an oil reservoir through a copper coil. What type and grade oil is this and should it be replaced? Thanks in advance, Ross Maramu. 1989 #261
