Boot
To verify the preload of the boot no. 10, proceed
as follows:
NOTE: To verify the boot preload and free length,
jet pump and drive shaft must be installed.
Measure boot length when normally installed on
drive shaft. Ensure circlip no. 5 is properly in-
stalled into groove.
1. Boot
A. Measure here
Push floating ring to compress boot; then, remove
circlip out of drive shaft groove.
1. Push floating ring
2. Remove circlip
Slide floating ring far enough forward in order to
release it from carbon ring.
Measure boot free length.
Subtract the installed length measurement from
the free length measurement. A difference of 4 mm
to 12 mm (5/32 in to 15/32 in) should be obtained.
If the length is less than 4 mm (5/32 in), install a
spacer (P/N 293 250 017) between boot and thru
hull fitting.
1. Spacer
NOTE: Drive shaft must be removed to install
spacer.
INSTALLATION
Installation is essentially the reverse of removal
procedure. However, pay particular attention to
the following.
Drive Shaft and Dampers
Install dampers no. 13 on drive shaft no. 12.
NOTE: Make sure dampers were not left in PTO
flywheel or impeller.
Install drive shaft and jet pump at the same time.
Insert drive shaft through carbon ring no. 8 and
floating ring no. 6.
NOTE: Make sure to install floating ring before in-
serting the drive shaft in the PTO flywheel.
While holding jet pump, guide and engage drive
shaft splines in PTO flywheel. Rotate shaft to
properly index splines. Make sure boot is well po-
sitioned over shaft end.
