LEAKAGE CHECK
To check for oil seal or o-ring leakage, use oil leakage tester.
Before leakage check, temporarily fasten the driveshaft bear-
ing housing to gearcase using two bolts and nuts (placed through
the two diagonally opposite gearcase mounting holes).
Apply the specified pressure through the oil level hole and ro-
tate the drive and propeller shafts.
If pressure does not fall, sealing performance is correct.
