Application
This unit describes the performance outcomes required to performance test a marine engine in a water tank. It involves preparing for the task, setting up the test equipment, performance testing the engine, 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.

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:
water test two different marine engines in tanks, including one outboard engine.
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 testing marine engines in water tanks, including procedures for:
lifting and supporting marine engines
working with rotating engine components
placing marine engines in test tanks
environmental requirements, including procedures for trapping, storing and disposing of fluids released from marine engines during water testing
application, purpose and operation of water testing tanks, including:
methods of mounting engines to test tank
engine test propellers
application, purpose and operation of marine engine test equipment, including:
oil pressure gauges
fuel pressure and flow gauges
tachometers
temperature probes
procedures for performance testing marine engines in water tanks, including load testing
procedures for compiling engine performance reports.
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 vessels or engines that they have tested in water tanks, 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 engine specifications
water tank for testing marine engines
two different marine engines requiring water testing in tanks
marine engine test equipment as specified in the knowledge evidence
tools, equipment and materials appropriate for water testing marine engines in tanks.
Foundation Skills
This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.
Skills | Description |
Learning skills to: | locate appropriate sources of information efficiently. |
Reading skills to: | interpret information from manufacturer and workshop literature when seeking marine engine’s specifications and procedures. |
Writing skills to: | legibly and accurately fill out engine performance report documentation when reporting findings and recording parts and material used. |
Oral communication skills to: | clarify instructions and report findings. |
Numeracy skills to: | interpret numbers on gauges and test instruments use basic mathematical operations, including addition and subtraction, to calculate deviations from manufacturer specifications. |
Planning and organising skills to: | plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes. |
Problem solving skills to: | determine most appropriate method of placing engine in test tank determine most appropriate testing equipment to gather data to required accuracy. |
Technology skills to: | use gauges and test instruments, such as oil pressure gauges, fuel pressure and flow gauges, tachometers and temperature probes. |
