  1. AM Clutch Selection for American MarineZ-Drive Product ETM 5121 Project Proposal Phillip Magee Feb 16, 2004

  2. AM • 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. AM • 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. AM • 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. AM • 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. AM • 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. AM • 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. AM • 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. AM • 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. AM • 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 clutch’s role in safe operation • Preliminary Hazard List • Team brainstorming effort, Benchmarking and ETBD will be presented to team

  11. AM • 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

  12. AM • Project Plan

  13. AM • Project Plan

  14. AM • Project Plan

  15. AM • 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
