Description
This unit involves the skills and knowledge required to operate inboard and outboard motors, and to diagnose basic faults.
Notes
Elements and Performance Criteria
1 Operate inboard and outboard motors
  • 1.1 Pre-start checks are performed on the motor
  • 1.2 Fuel is checked to ensure there is adequate fuel, including a reserve, on board
  • 1.3 Motor is started and stopped safely and correctly
  • 1.4 Motor controls are used to manoeuvre the vessel safely to complete work tasks
  • 1.5 Motor is operated within safe limits during normal manoeuvres
2 Secure vessel on completion of work task
  • 2.1 Vessel is moored safely
  • 2.2 Fuel system is closed down
  • 2.3 Vessel is secured
  • 2.4 Fuel is stored to minimise environmental and fire hazards where appropriate
  • 2.5 Unserviceable equipment is reported and tagged out as unserviceable
3 Maintain inboard and outboard motors
  • 3.1 Fuel filters are drained of excess water
  • 3.2 Batteries and connections are maintained to ensure reliable electrical supply to the motor
  • 3.3 Engine and gearbox oil is checked and lubrication is applied
  • 3.4 Engine mounting gear is checked as necessary
4 Identify basic inboard and outboard motor faults
  • 4.1 Operating difficulties caused by fuel-related factors are identified
  • 4.2 Electrical faults are identified, tagged out and reported
  • 4.3 Motor propulsion faults are identified, tagged out and reported
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.
Pre-start checks may include:
Amount of fuel in the fuel tank
Appropriate fuel
Cooling water intake submerged
Fuel hose connected, full and free of restrictions
Fuel tank depressurised
Motor attachment points
Water depth
Started may include:
Electric start
Pull start
Propulsion faults may include:
Bent or broken propeller
Broken shear pin or drive spline
Fouling
Spark plugs

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, the required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the Elements, Performance Criteria, Required Skills, Required Knowledge and include:
working safely at all times
scheduling manufacturer specified maintenance.
Context of and specific resources for assessment
Performance is demonstrated consistently over time and in a suitable range of contexts.
Resources for assessment include access to:
industry-approved marine operations site where using an inboard and outboard motor to handle a vessel in sheltered waters may be conducted
tools, equipment and personal protective equipment currently used in industry
relevant regulatory and equipment documentation that impacts on work activities
range of relevant exercises, case studies and/or other simulated practical and knowledge assessments
appropriate range of relevant operational situations in the workplace.
In both real and simulated environments, access is required to:
relevant and appropriate materials and equipment
applicable documentation including workplace procedures, regulations, codes of practice and operation manuals.
Method of assessment
Practical assessment must occur in an:
appropriately simulated workplace environment and/or
appropriate range of situations in the workplace.
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate to this unit:
direct observation of the candidate using an inboard and outboard motor to handle a vessel in sheltered waters
direct observation of the candidate applying relevant WHS/OHS requirements and work practices.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
In all cases where practical assessment is used it should be combined with targeted questioning to assess Required Knowledge.
Assessment processes and techniques must be appropriate to the language and literacy requirements of the work being performed and the capacity of the candidate.
