  • Emissions data is mostly sourced from the USA EPA certification database.   Each manufacturer conducts their own testing, to ISO8178 Test cycle E4 and submits the data to the USA EPA, for audit.
  • The star rating is our own scoring system, and is based on the CARB system.
    • Zero Stars – over 250g/kw/hr  HC+Nox
    • One star  - 64.8 to 250
    • Two star – generally  less than 64.8
    • Three Star  - generally less than 30, for up to 4hp and as low as 16.1 for the largest outboards.

     

    For the mathematically inclined the two and three star scales are exponential: a sliding scale that asks for tougher standards for larger engines.

    2 Star

    Outboards that do not meet 3 Star may be rated 2 star which is identical to CARB 2 Star.    The upper limit is not 64.8, but on a sliding scale from 64.8 for the smallest outboards down to 36.0 for the largest engines The formula, is

    Where p is in kW a P>4.3kW

    If p< 4.3kW  the limit =64.8

     

    3 Star

    Starting at the highest level the 3 star is exactly equal to the CARB 3 Star scheme. The upper limit is not 30, but on a sliding scale from 30 for the smallest outboards down to 16.1 for the largest engines as illustrated in figure 1.    The formulae for the limit of HC+NOx in g/kw/hr is:
