BWC Test Results
6
Repeat Testing at Grady White
No degradation in capacity was identified
7
Summary

• Testing showed no degradation in capacity due to
  moisture or liquid gasoline exposure
• Regenerable carbon capacity was maintained
  throughout test period
• Carbon capacity was unaffected by physical
  stresses associated with marine use
• Carbon canisters did not affect performance of
  boats

8
Future Work

• Carbon canisters will be removed from boats and
  tested for particle size distribution, heel
  analysis, and capacity
• Two canisters will remain on boats for long-term
  testing
