Clutch Selection for American MarineZ-Drive
Product

• ETM 5121 Project Proposal
• Phillip Magee
• Feb 16, 2004

2

• Introduction
• Proposal
• Individual effort
• Introduce self selected project to American
  Marine Management and MSETM Faculty
• Unclassified
• Company names, product names, and data are
  sanitized to protect trade secrets and
  proprietary information

3

• Opportunity Statement
• American Marine designs and manufactures z-drive
  marine power systems
• Z-drive product description
• Transmit power from an automotive style engine to
  a propeller
• Steer, trim, and trailer the gearcase and
  propeller
• Provide for shifting power (Forward Neutral
  Reverse)

4

• Opportunity Statement
• American Marine currently produces the following
  z-drive products to serve the recreational and
  light commercial marine market
• Charlie drive
• Basic design 1965
• 130 300 HP
• Single propeller only
• Several gear ratios
• Delta Drive
• Basic design 1986
• 230 575 HP
• Single sport, low speed, and dual propeller
• Several gear ratios
• Standard, Diesel, Performance, and Racing versions

5

• Opportunity Statement
• Charlie and Delta drives are similar simple and
  robust
• 2002 and 2003 J.D. Power surveys ranked them
  below their only major competitor (Volvo) in
  shift characteristics
• Small incremental improvements have been made to
  the clutch and drivetrain components for over 40
  years
• The current shift mechanism designs are nearing
  the end of their life span and are difficult to
  improve
• A new z-drive program has been approved and
  opportunities to improve the shift
  characteristics (Noise, Vibration, Harshness) are
  available

6

• Measures
• Timeliness
• Projected schedule vs. actual schedule
• Professionalism
• Clear and concise documentation
• Team Member Buy-In
• How many other decisions uses these processes in
  2004 and 2005?
• Ability to select clutch and obtain approval
• Is the outcome of the effort successful?

7

• Project Objectives
• Provide useful and relevant information to
  American Marine Mgmt. regarding clutch selection
  for future z-drive products
• Information on available clutch types
• Information on clutch safety
• Information on clutch performance attributes and
  cost
• Suggestion for future clutch type

8

• Specific Deliverables
• Benchmark study
• Internal, competitive, functional
• Energy trace and barriers diagram (ETBD)
• Preliminary hazard list
• Preliminary hazard analysis
• Failure modes and effects analysis process
• Decision analysis

9

• Alternatives to be Considered
• Clutches currently used in the marine,
  automotive, or off-highway vehicles will be
  considered
• Dog Clutch
• Charlie drive, all outboard engines
• Cone Clutch
• Delta drive, all Volvo drives
• Wet Disk Clutch
• Inboard marine transmissions, automatic
  automotive and off-highway transmissions
• Dry Disk Clutch
• Manual or automated manual automotive and
  off-highway transmissions

10

• Project Approach Criteria for Evaluating
  Alternatives
• Proposal Completion
• Individual effort
• Benchmarking Research and Documentation
• Individual effort with support of internal
  experts
• ETBD
• Individual effort that diagrams energy flow and
  barriers to better understand the clutchs role
  in safe operation
• Preliminary Hazard List
• Team brainstorming effort, Benchmarking and
  ETBD will be presented to team

11

• Project Approach Criteria for Evaluating
  Alternatives
• Preliminary Hazard Analysis
• Team FMEA
• Decision Analysis
• Team effort, criteria for evaluating clutch
  alternatives will be generated and weighted
• Project Documentation and Final Report
• Individual effort, combines the data from all
  of the processes and contains suggestion for
  clutch selection

15

• Planned Use of ETM Materials
• Benchmarking
• The benchmarking portion of this report will
  use the concepts learned for process
  benchmarking in a light product benchmarking
  exercise.
• System Safety
• The PHL and PHA processes learned in the system
  safety class will be utilized in order to help
  direct a design choice in early design stages.
• Failure Modes and Effects Analysis
• FMEA processes presented in the FMEA course will
  be used to complete the PHA
• Problem Solving and Decision Making
• The Kempner Tregoe decision analysis process
  presented in the problem solving and decision
  analysis course will be utilized to evaluate the
  clutch alternatives
