password,

the

process

proceeds

to

S30

as

a

wrong

password,

thereby

stopping

the

communication

with

the

transponder

9.

[0049]

On

the

other

hand,

when

the

password

in

the

received

ID

code

coincides

with

the

regular

password,

the

process

proceeds

to

S27

in

which

the

display

section

18

corresponding

to

the

engine

speci?cation

determined

in

S20

to

S24

is

?ashed

(S27).

This

allows

an

operator

to

be

noti?ed

of

the

engine

speci?cation

corresponding

to

a

to-be-prepared

ID

code

of

a

transponder.

When

there

is

no

correspondence

with

any

of

the

previously

speci?ed

engine

speci?cations

in

S20

to

S24,

the

process

proceeds

to

S25

in

which

commu

nication

with

the

transponder

9

is

determined

to

fail.

[0050]

Next,

the

power

source

terminal

b

in

the

micro

computer 14

is

monitor

(S28)

in

which,

when

the

power

source

terminal

b

is

in

the

HI

state

(i.e.,

state

in

which

the

currently-used

lock

plate

5

is

inserted

to

the

stop

switch

knob

3),

time

monitoring

is

carried

out

(S31)

and,

when

three

minutes

have

passed

since

the

HI

state

is

continually

provided,

the

process

proceeds

to

S32

in

which

the

stand-by

state

is

provided

(and

LED

stops

?ashing).

On

the

other

hand,

when

the

power

source

supply

to

the

power

source

terminal

b

is

in

the

LO

state

within

three

minutes

(i.e.,

state

in

which

the

currently-used

lock

plate

5

is

disengaged

from

the

stop

switch

knob

3),

the

LED

in

the

display

section

18

stops

?ashing

(S29).

[0051]

Then,

the

lock

plate

5

attached

with

another

tran

sponder

is

inserted

to

the

stop

switch

knob

3.

Another

transponder

has

an

ID

code

in

which

only

an

engine

speci

?cation

is

previously

speci?ed

and

no

unique

password

is

written.

Speci?cally,

in

this

embodiment,

only

a

unique

password

in

the

regular

ID

code

of

the

transponder

is

written

to

another

transponder

to

prepare

a

back-up

transponder

(lock

plate).

Alternatively,

both

of

the

engine

speci?cation

and

unique

password

in

the

regular

ID

code

of

the

transpon

der

may

be

written

to

another

transponder.

[0052]

When

another

lock

plate

(the

one

attached

with

a

blank

transponder)

is

attached

by

S33

is

determined,

then

what

is

the

information

for

specifying

engine

performance

that

the

transponder

has

previously

speci?ed

is

determined

(S34

to

S38).

When

the

information

is

determined

as

speci

fying

any

of

the

previously

speci?ed

engine

speci?cations,

the

process

proceeds

to

S40

in

which

the

regular

password

of

the

transponder

is

written

to

the

transponder

attached

to

another

lock

plate.

When

the

information

is

determined

as

not

specifying

any

of

the

previously

speci?ed

engine

speci

?cations

in

S34

to

538,

the

process

proceeds

to

S39

in

which

it

is

determined

that

communication

with

a

new

transponder

is

determined

to

fail.

[0053]

When

the

regular

password

of

the

transponder

is

written

to

the

transponder

attached

to

another

lock

plate,

S41

locks

further

processings

in

order

to

prevent

the

transponder

from

being

written

again.

Thereafter,

the

new

transponder

is

communicated

again

to

check

the

written

password

(S42).

When

the

password

is

con?rmed

as

the

regular

one,

the

LED

in

the

display

section

18

corresponding

to

the

speci?ed

engine

speci?cation

is

?ashed,

thereby

allowing

the

micro

computer 14

to

restart

the

monitoring

of

the

power

source

terminal

b

(S45).

[0054]

On

the

other

hand,

when

S41

determines

that

the

password

written

to

the

new

transponder

is

different

from

the

regular

one,

the

process

proceeds

to

S43

in

which

the

LED

Dec.

23,

2004

corresponding

to

the

speci?ed

engine

speci?cation

in

the

display

section

18

is

?ashed

at

double

speed,

then

allowing

S45

to

monitor

the

power

source

terminal

b.

When

the

power

source

supply

to

the

power

source

terminal

b

is

in

the

HI

state

(i.e.,

when

the

new

lock

plate

is

inserted

to

the

stop

switch

knob),

then

time

monitoring

is

carried

out

(S46).

When

three

minutes

have

passed

since

the

HI

state,

the

process

proceeds

to

S47

in

which

the

stand-by

state

is

provided

(and

the

LED

stops

?ashing).

On

the

other

hand,

when

the

power

source

supply

to

the

power

source

terminal

b

is

in

the

LO

state

within

three

minutes

(i.e.,

when

the

new

lock

plate

is

disengaged

from

the

stop

switch knob),

the

LED

in

the

display

section

18

stops

?ashing

(S48).

[0055]

In

this

way,

the

operation

for

writing

the

regular

ID

code

of

the

transponder

to

another

transponder

is

completed.

In

order

to

carry

out

the

same

writing

operation

for

other

transponders,

the

subsequent

steps

of

S49

(in

which

a

lock

plate

attached

with

other

transponders

is

inserted

to

a

stop

switch

knob)

and

S50

(in

which

an

ID

code

is

written

to

the

transponder)

are

performed.

The

engine

control

apparatus

for

the

small

motorboat

according

to

the

above

embodiment

allows

a

user

to

prepare

a

back-up

transponder

in

an easy

manner.

[0056]

The

embodiment

is

described

as

in

the

above,

however,

the

present

invention

is

not

limited

to

this.

For

eXample,

the

transponder

9

also

may

be

inserted

to

and

buried

in

the

lock

plate.

Alternatively,

the

LED

as

the

display

section

18

also

may

be

provided with

another

position

in

the

switch

case

1

in

addition

to

the

position

in

this

embodiment.

The

display

section

18

(not

limited

to

LED)

also

maybe

provided

at

a

position other

than

the

one

in

the

switch

case

1.

[0057]

The

writing

section

16

according

to this

embodi

ment

attaches

or

detaches

from

the

writing

code

16a

to

allow

the

microcomputer

14

in

the

control

section

11

to

determine

whether

the

operation

is

a

normal

operation

or

a

writing

operation.

Instead

of

this,

the

switches

are

placed

in

the

wiring

L5

(see

FIG.

5),

and

determination

between

a

normal

operation

and

a

writing

operation

also

may

be

carried

out

by

turning

the

above

switches

on/off.

Although

this

embodi

ment

is

applied

to

a

small

motorboat,

this

embodiment

also

maybe

applied

to

other

machines

(e.g.,

ATV

or

snowmo

bile).

[0058]

According

to

the

invention

of

Aspect

1,

the

writing

section

can

be

used

to

write

a

regular

ID

code

of

a tran

sponder

to

another

transponder,

thus

allowing

the

user

to

easily

prepare

a

back-up

transponder

in

a

case

where

the

transponder

is

lost.

[0059]

According

to

the

invention

of

Aspect

2,

the

control

section

changes

the

engine

performance

based

on

the

ID

code

from

the

transponder.

When

the

writing

section

writes

a

regular

ID

code

of

a

transponder

to

another

transponder,

a

to-be-speci?ed

engine

performance

can

be

changed.

Thus,

a

plurality

of

back-up

transponders

for

which

an

engine

per

formance

can

be

speci?ed

arbitrarily

can

be

prepared.

[0060]

According

to

the

invention

of

Aspect

3,

the

display

section

is

provided

for

displaying

the

differences

in

engine

performance

speci?ed

for

the

transponder.

Thus,

the

differ

ences

in

of

the

performance

can

be

recogniZed

and

checked

both

in

a

normal

operation

and

a

writing

operation.
