Repair - lower gear housing,
sailboat drive
1. Clean the outside of the drive. Remove the propel-
ler and remove the fishing line cutter. Unscrew the
drain plug and drain off the oil.
2. Remove the locking wire from the four socket cap
screws below the division line of the drive, two on
each side. Throw the wire away.
Then remove all the (10) screws.
3. Separate the upper and lower gear housings. Re-
move and scrap the gasket at the division line.
Remove the shims. Note the number of shims.
Remove the spacer ring ( 1 ). Tap the shaft lightly with
a plastic-faced hammer.
4. Fix fixture 884753 in a vise. Install the lower gear
housing in the fixture, so that the four pins fit the cut-
outs in the shaft nut. Fix the gear housing with four of
the socket cap screws.
Install tool 884264 or 884830 on the shaft. Use a
17 mm socket and undo the nut by turning the shaft
clockwise.
NOTE ! Only turn enough to make the nut just come
into contact with the fixture.
Remove the fixture from the lower gear and screw the
nut off the shaft.
