Shaft-Transmission Alignment
Alignment between the engine transmission
output shaft and the propeller is very critical.
The alignment has been performed at the fac-
tory and was rechecked by the dealer after the
boat had been in the water for 48 hours.
•
An alignment inspection should be per-
formed by a marine mechanic as part of
the routine maintenance program after the
initial 30 hours of operation, then every 60
hours and whenever unusual noise or
vibration is noticed.
•
Shaft-transmission alignment should be
performed by a marine mechanic since it
requires moving the engine and prop shaft.
•
To insure proper alignment after a haulout
or dry storage, wait 48 hours after launch-
ing before final alignment adjustments by
a marine mechanic are made.
Shaft Log Packless Sealing System
The shaft log packless sealing system’s shaft seal is a maintenance-free, watertight seal that doesn’t require packing
or adjustments.
Oil Change System (Option)
Your yacht may be equipped with an oil change
pump to simplify draining and filling engine and
generator oil. See the operationing instructions
included in your owner’s packet for information
on the use of this system.
