Proper.performance.of.the.shaft.seal.is.directly.
dependent.upon.correct.propeller.shaft.alignment..
Propeller.damage,.a.bent.strut.or.shaft,.or.abnormal.
wear,.settling,.etc.,.are.common.reasons.for.misalign-
ment..Therefore,.periodically.have.the.shaft.alignment.
checked.and.have.adjustments.made.when.neces-
sary..
C. Propeller Shaft
NOTICE
When.lifting.the.boat,.always.position.the.lifting.
straps at the corresponding “sling” labels.
Lifting.the.boat.with.lifting.straps.over.the.prop.
shafts.will.cause.the.shafts.to.become.bent..
Improper.lifting.technique.will.not.be.covered.
under.warranty.
.
To.prevent.personal.injury,.keep.away.
from.the.propulsion.machinery.during.
its.operation.or.whenever.the.boat.is.in.
motion..Movement.of.water.past.a.pro-
peller.can.cause.the.propeller,.propeller.
shaft,.and.other.propulsion.machinery.
to.rotate.even.if.that.equipment.is.not.
being.operated.intentionally.
The.prop.shafts.of.all.our.V-drive.boats.are.aligned.at.
the.factory..Prop.shaft.alignment.should.be.checked.
by.your.dealer.during.pre-delivery.service..Shaft.
alignment.should.be.checked.again.forty-eight.hours.
after.initial.commissioning..Periodic.checks.of.shaft.
alignments,.and.engine.V-drive.mounting.bolts.should.
be.made;.especially.if.noise.or.vibration.occurs.

NOTICE
Prop Shaft
Strut
Zinc Anode
Excessive vibration, abnormal shaft log wear,
or broken propeller shaft coupling bolts are an
indication of misalignment. Misalignment can
also cause severe damage to shaft logs, struts,
shafts and the engine transmission or v-drive.
Realignment should only be performed by a
qualified service person. The following proce-
dures are provided so a boat owner can
determine if service work is required.
Shaft Log

Assembly
Figure E-3: Underwater Equipment
The.propeller.shaft.coupling.and.engine/V-drive.output.
flange coupling must be aligned to within 0.004
inches..Always.be.sure.the.prop.shaft.is.centered.in.
the.strut.bearing.and.shaft.log.before.alignment.
adjustments.are.made..Refer.to.Figure.E-4.
To prevent water from entering into the boat,
always be sure the lock nuts are tightened
securely to prevent the packing nuts from
loosening. DO NOT attempt to tighten the lock
nuts without the proper equipment to hold the
packing nut stationary.
B. Strut
The.strut.secures.the.lower.end.of.the.propeller.shaft..
Seasonal.inspection.of.each.strut.should.be.made.to.
insure.no.damage.has.incurred.and.the.strut.bearing.
is.not.worn.excessively.
When.the.boat.is.removed.from.the.water.for.winter-
ization.or.general.maintenance,.apply.a.light.water.
proof.grease.to.the.strut.bearing.(rubber.sleeve.in.the.
strut).and.the.shaft.where.it.penetrates.the.strut.
bearing..This.will.keep.the.strut.bearing.from.drying.
out..Replace.the.strut.bearing.should.it.become.worn.
or.cracked.
