ENGINE ADJUSTMENTS
ENGINE COMPRESSION TEST
To check the engine's compression pressure, warm up the
engine, then shut it down.
1. Remove both spark plug caps and both spark plugs.
2. Install a compression adapter and gauge in a spark
plug hole.
3. Close the thru hull valve (seacock).
4. Crank the engine several times quickly so that the gauge
pointer reaches it's maximum.
STANDARD COMPRESSION PRESSURE AT 5DD RPM:
71 PSI (5± 1 Kg/cm') (D.4± D.1 MPa)
5. Test the compression pressure on the other cylinder.
If either cylinder is below the standard
try adding a
small amount of engine oil through the spark plug hole
and repeat the test.
(a) If additional oil causes an increase of pressure,
the piston ring and/or cylinder may be worn
or damaged.
(b) If additional oil does not increase compression
pressure suspect poor valve contact, valve seizure
or valve wear.
6. Reinstall the two plugs, connect the wires and open the
thru hull valve (seacock).
WATER PUMP BELT
To remove, replace or adjust the belt, loosen the pivot bolt
and release the adjusting bolt. Slide the water pump bracket
to slacken the belt for removal. When replacing and
adjusting the belt, set the belt very tight and tighten the bolt
and nut.

REMOTE OIL FILTER (OPTIONAL)
INSTALLATION
This popular accessory is used to relocate the engine's oil
filter from the engine to a more convenient location such as
an engine room bulkhead.
NOTE:
Refer to ENGINE OIL CHANGE in this manual for
instructions on removing the oil filter.
A
CAUTION:
.It is vital to install the oil lines cor-
rectly. If the oil flows in the reverse direction, the by-
pass valve in the filter assembly will prevent the oil
from reaching the engine causing an internal engine
failure. If there'is no oil pressure reading, shutdown
imnledJ
