GENERAL INFORMATION and SPECIFICATIONS - 1-1790-817643R1 DECEMBER 1996
Periodic Inspection
Conduct a periodic, systematic inspection to uncover and
correct a failure before it can cause inconvenience or me-
chanical damage. Inspection interval is based on average
operating conditions in recreation service. Under severe
conditions, the inspection interval should be shortened. In-
spection includes:
1. Clean entire unit thoroughly, including all accessible
powerhead parts.
2. Check entire unit for loose, damaged or missing parts.
Tighten or replace as required.
3. Lubricate gear housing.
4. Lubricate other points as indicated, previously.
5. Lubricate starter motor shaft with light film of SAE 10W
motor oil. Do not over-lubricate.
6. Service spark plugs. Inspect spark plug leads and
electrical leads for damage or deterioration, as ex-
plained in Section 2 “Electrical and Ignition”.
7. Inspect fuel lines for damage or deterioration and ser-
vice fuel filters as indicated in Section 3 “Fuel System
and Carburetion.”
8. Remove propeller and inspect. Trim nicks and burrs
with a file, being careful not to remove more metal than
absolutely necessary. Inspect for cracks, damage or
bent condition. If condition is doubtful, refer to autho-
rized Quicksilver Propeller Repair Station facilities.
Before reinstalling propeller, coat propeller shaft with
Quicksilver Special Lubricant 101, Anti-Corrosion
Grease or 2-4-C w/Teflon Marine Lubricant.
9. Inspect the outboard surface finish for damage or
corrosion. Thoroughly clean damaged or corroded
areas and apply matching paint (Quicksilver Spray
Paints).
10. Check trim tab and galvanic corrosion sacrificial anode
for damage or for deterioration from salt water
operation.
11. Check remote controls and steering. Be sure that all
connections and fittings are in good condition, properly
secured and correctly adjusted.
Flushing Outboard Cooling System
! WARNING
When flushing, be certain that area in vicinity of pro-
peller is clear and that no person is standing nearby –
to avoid possible injury. It is recommended to remove
propeller as a precautionary measure.
1. Install Quicksilver Flushing Attachment (73971A2) [or
equivalent tool] on the gear housing from the FRONT
side, positioning the rubber cups over the water intake
openings.

a - Water Hose (1/2 in. [13mm] I.D. or Larger)
b - Flushing Attachment (73971A2)
(Typical Gear Housing)
2. Connect hose (1/2 in. [13mm] I.D. or larger) between
flushing attachment and water tap.
IMPORTANT: To prevent water pump damage, do not
start or run engine unless cooling water is flowing.
3. With the outboard in normal operating position (verti-
cal), partially open water tap (IT MAY NOT BE NECES-
SARY to use full water pressure) and adjust water flow
so that there is a significant water loss around the rub-
ber cups.
