Test Preparations
WARNING!
NEVER leave the helm unattended
when performing tests with the boat in the
water.
NOTICE: During operation ensure that the engine
seawater pump suction does not collapse the hose
to the water source, causing the engine water
supply to stop.
1. Ensure that there is a sufficient supply of
coolant to the drive unit seawater inlet holes
and / or the through-hull-seawater inlet holes.
2. Use the correct flushing attachment for the
seawater pickup found on the drive unit.
CAUTION!
If using a flush test device
(attachment), install over the seawater intake
holes and connect a water hose. NEVER use
full water tap pressure. Also, avoid operating
the engine above 1500 rpm, because the
suction created could cause the water hose
to collapse causing the water supply to be cut
off.
3. Check all engine-related items as specified by
the engine manufacturer. See the engine
manufacturer's instructions.
Note: See the
Operation Manual
provided with
your engine / vessel for operating
specifications and fluid capacities.
4.
NOTICE: The drive unit oil level in the oil
reservoir will rise and fall during the drive unit
operation. Always check the oil level in the
reservoir when the drive unit is cool and when
the engine is shut down.
5. Check the drive unit oil level in the oil reservoir.
6. Test the audio warning system, if equipped.
Engine Operation Tests
WARNING!
If engine is to be tested with the
boat out of the water, the propeller must be
removed to avoid injury.
CAUTION!
Overheating from insufficient
coolant will cause engine and drive unit
damage. Ensure that there is sufficient water
available at the water inlet holes during
operation.
1. Ensure that the coolant system drain plugs and
petcocks are installed and tight.
2. Ensure that the coolant system hoses are
installed and clamped securely.
Out-of-Water Testing
The following information is for engine operation
tests with the boat out of the water:
NOTICE: On vessels with the drive unit seawater
inlet blocked off at the gimbal housing and using a
through-the-hull seawater inlet, a constant supply
of coolant must be available for both the drive unit
and the engine during operation.
1. Install a flushing attachment over the drive unit
and / or the alternate seawater inlet pickup
holes.
2. Connect a hose between the flushing
attachments and a water source.
NOTICE: If using a flushing attachment
(sometimes referred to as a flush test device)
over the seawater inlet holes and a water hose as
shown, NEVER use full water source pressure.
Open the water source about 1/2 maximum.
NEVER use full water pressure.
