Priming The Oil System - Evinrude E-TEC 90 H.O. Original Instructions Manual

You must use an oil tank equipped with a filter
and an oil supply hose. The oil system must
be purged if air is in the oil supply hose. Refer
to Priming the Oil System on page 19.
Install the oil tank following the instructions
provided with the unit.
NOTICE
Consider the installation loca-
tion of the oil tank carefully. The oil tank is
vented to the atmosphere. To avoid seri-
ous powerhead damage, be sure the oil
tank is installed in a location that does not
allow constant exposure to sunlight, rain,
bilge water, or spray. Periodically inspect
the oil tank for evidence of water.
Filling the Oil Tank
Remove the filler cap and fill the tank with rec-
ommended outboard lubricant, as specified in
Oil Requirements on page 18. Replace the
filler cap and tighten securely. If you run the
