Glenn,
Mike,
Alan,

The
attached
email
covers
some
of
the
discussions
I've
had
with
Jeff
Lowry
at
CARB
regarding
the
over
500
Hp
engines.
I
believe
he
discussed
the
default
value
with
you
and
said
that
you
were
planning
on
setting
it
at
30
g/
kW­
hr.
The
other
issues
are
useful
life
and
emissions
warranty
which
need
to
be
modified,
as
these
are
highly
stressed,
short
lifetime
engines.

If
we
can
agree
to
these
items,
then
the
only
other
real
issue,
for
these
engines,
is
how
the
Averaging
and
Trading
is
handled
for
companies
that
need
it.
Jeff
has
indicated
that
CARB
wants
to
be
in
alignment
with
EPA
on
this
issue.

Regards,

Re:

Thanks,

Most
of
these
requests
seem
reasonable
to
me
although
I'll
need
to
review
the
warranty
provisions
to
see
what
we
can
allow.
I'll
pass
this
on
to
my
management.
Thanks.

Jeff,

Per
our
discussion
today,
here
are
our
proposed
changes,
for
over
500
Hp
engines,
in
the
SI
Marine
Engine
Rule:

Default
Emissions
Value:

You
and
EPA
have
suggested
30
g/
kW­
hr
HC
+
NOx.
We
concur.
We
do
want
the
option
of
testing,
and
using
actual
values,
if
desired
(
harmonizes
with
EPA
approach).

Useful
Life:

Under
650
Hp
Engines
­
75
hours
Reason:
These
engines
have
stock
blocks,
but
High
Performance
Heads.
Some
have
Superchargers.
Primary
durability
issue
is
the
Heads.

Over
650
Hp
Engines
­
50
hours
Reason:
These
are
Racing
Blocks
and
Heads,
and
are
extremely
highly
stressed
engines.
They
run
large,
or
multiple
Superchargers.
Recommended
interval
for
rebuilding
heads
is
50
hours.

Emissions
Warranty:

Under
650
Hp
Engines
­
1
year
(
We
also
request
that
you
consider
allowing
us
to
either
use
hours
or
time.
If
hours
we
proposes
75
hours
­
useful
life).

Over
650
Hp
Engines
­
Minimum
90
days,
but
must
match
engine
warranty.
In
our
case
the
850
Hp
has
a
6
month
warranty
and
the
1075
Hp
has
a
90
day
warranty.
(
We
also
request
that
you
consider
allowing
us
to
either
use
hours
or
time.
If
hours
we
proposes
50
hours
­
useful
life).

OBD­
M:

Per
our
discussion,
the
references
for
relief
on
implementation
need
to
be
changed
from
2007
to
2008
to
preserve
the
amount
of
relief
time
available.

Please
feel
free
to
call
me
to
discuss
this,
or
any
other
issues.
I
look
forward
to
working
with
you
towards
resolving
all
of
the
open
issues.
