3. Open the seacock.
NOTICE
Without sufficient cooling water, the engine, the water pump, and other components will overheat and suffer damage. Provide
a sufficient supply of water to the water inlets during operation.
4. Verify that the seawater pickup pump is supplied cooling water.
5. Start the engine and check for leaks.
Boat Bottom Care
To achieve maximum performance and fuel economy, the boat bottom must be kept clean. Accumulation of marine growth or
other foreign matter can greatly reduce boat speed and increase fuel consumption. To ensure best performance and efficiency,
periodically clean the boat bottom in accordance with manufacturer's recommendations.
In some areas, it may be advisable to paint the bottom to help prevent marine growth. Refer to the following information for
special notes about the use of antifouling paints.
Drive Belt
Serpentine Belt Failure Identification
Appearance
Description Cause Solution
Abrasion
Each side of the belt appears
shiny or glazed. Severe
condition: Fabric is exposed.
Belt is in contact with an object.
Can be caused by improper belt
tension or tensioner failure.
Replace the belt and
inspect for contact with an
object. Verify the belt
tensioner is functioning.
Pilling
Belt material is sheared off from
the ribs and builds up in the belt
grooves.
There are a number of causes
including lack of tension,
misalignment, worn pulleys, or a
combination of these factors.
When pilling leads to belt
noise or excess vibration,
the belt should be
replaced.
Improper install
The belt ribs begin separating
from the joined strands. If left
unattended, the cover will often
separate, causing the belt to
unravel.
Improper belt installation is a
common cause of premature
failure. One of the outermost belt
ribs is placed outside the pulley
groove, causing a belt rib to run
without a supporting or aligning
pulley groove.
The belt life has been
severely limited and
should be replaced
immediately. Ensure all
ribs of the replacement
belt fit into the pulley
grooves. Run the engine.
Then, with the engine off
and battery disconnected,
inspect the belt for proper
installation.
