switch to MANUAL and listening for the pump

running and check to see that bilge water is

being pumped overboard.

Close engine compartment.

4. Check fuel level. Be sure

you have enough fuel for

your trip. Remember the

“1/3 Rule”: Use no more

than 1/3 of your fuel for

outbound trip; use 1/3 of

the fuel for return trip; keep

1/3 for reserve in case of

emergency.

5. Run bilge blowers for at

least 4 minutes before

attempting to start engine

Unlike your automobile

engine which is naturally

ventilated even when it is

not moving, your boat

engine compartment (the bilge) does not have

sufficient natural ventilation when the boat is not

moving or moving slowly. That is why the engine

compartment must have forced ventilation,

using the bilge blower, to remove potentially

explosive gasoline vapors, before the engine is

started and when the boat is moving slowly.

Because it may be difficult to remember to turn

on the bilge blower every time you slow down

the boat, it is recommended that the bilge blower

run all the time the engine is running.

6. Place drive unit in full DOWN/IN position.

7. Put throttle and shift

control lever into neutral;

then for a:

COLD ENGINE - press

THROTTLE ONLY button

lever forward to full open

throttle, then return to

about 1/4 throttle. In cold weather, it may be

necessary to pump lever several times before

engine will start.

WARM ENGINE - Press THROTTLE ONLY

button and move shift/throttle lever about 1/4

open throttle position. Do not pump lever.

FLOODED ENGINE - press THROTTLE ONLY

button and move shift/throttle lever to full open

position. DO NOT pump lever. When the engine

starts, move shift/throttle lever back rapidly to

decrease engine speed to between 1000 and

1500 RPM.

8. TO START ENGINE:

Turn ignition key

clockwise, as in a car, and

release when engine

starts. Do not crank

engine for more than a few

seconds if it doesn’t start.

Engine may be very cold

or flooded; see step 7.

9. After engine starts, reduce speed to between

1000 and 1500 RPM and check oil pressure.

10. If oil pressure is correct,

let engine warm up to

normal temperature range

as specified in the engine

manual, before shifting into

forward or reverse gear.

IF ENGINE

TEMPERATURE GOES

ABOVE NORMAL

RANGE. SHUT DOWN

THE ENGINE

IMMEDIATELY. GET

TRAINED HELP TO

FIND AND FIX THE
