Application
This unit describes the performance outcomes required to inspect and service inboard propeller drive systems on vessels. It involves preparing for the task, inspecting the system, reporting the inspection findings, servicing and adjusting the system, and completing workplace processes and documentation.
It applies to those working in the marine service and repair industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

3. Service propeller drive system | 3.1 Service and adjustments are carried out according to manufacturer specifications, workplace procedures, and safety requirements, and without causing damage to components or systems 3.2 Post-service testing is carried out according to workplace procedures |
4. Complete work processes | 4.1 Final inspection is made to ensure work is to workplace expectations and vessel is presented ready for use 4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected 4.3 Tools and equipment are checked and stored according to workplace procedures 4.4 Workplace documentation is processed according to workplace procedures |
Evidence of Performance
Before competency can be determined, individuals must demonstrate they can perform the following according to the standards defined in this unit’s elements, performance criteria, range of conditions and foundation skills:
inspect and service three different vessels with inboard propeller drive systems.
Evidence of Knowledge
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to inspecting and servicing inboard propeller drive systems, including procedures for identifying hazards and controlling risks associated with working with rotating shafts and component sharp edges
identification and function of inboard propeller drive system components, including:
stern tube
propeller shaft and coupling
'A' frame strut
'I' strut
cutlass bearing
stern tube bearings
basic operation of inboard propeller drive systems
types and applications of lubricants and lubricating fluids for inboard propeller drive systems
inspection procedures for inboard propeller drive systems, including procedures for checking clearances
service and adjustment procedures for inboard propeller drive systems, including:
adjusting or replacing components
greasing components
post-service testing procedures for inboard propeller drive systems, including procedures for:
checking alignment
checking for abnormal noises.
Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the marine inboard propeller drive systems that they have worked on, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
marine repair workplace or simulated workplace
workplace instructions
manufacturer inboard propeller drive system specifications
three different vessels with inboard propeller drive systems requiring servicing
tools, equipment and materials appropriate for inspecting and servicing marine inboard propeller drive systems.
