90-824052R3 JUNE 2002 IMPORTANT INFORMATION - 1C-5
Propeller Selection
For best all around performance from your
outboard/boat combination, select a propeller that
allows the engine to operate in the upper half of the
recommended full throttle RPM range with the boat
normally loaded (refer to Specifications). This RPM
range allows for better acceleration while
maintaining maximum boat speed.
If changing conditions cause the RPM to drop below
the recommended range (such as warmer, more
humid weather, operation at higher elevations,
increased boat load or a dirty boat bottom/gear case)
a propeller change or cleaning may be required to
maintain performance and ensure the outboard’s
durability.
Check full-throttle RPM using an accurate
tachometer with the engine trimmed out to a
balanced-steering condition (steering effort equal in
both directions) without causing the propeller to
“break loose”.

Propellers & Gear Housings
WARNING
Avoid serious injury from flying debris. Avoid se-
rious injury from airborne particles. Use eye and
breathing protection with proper ventilation.
PROPELLERS
1. Sand the entire area to be painted with 3M 120
Regalite Polycut or coarse Scotch-Brite, disc or
belts.
2. Feather edges of all broken paint edges. Try not
to sand through the primer.
3. Clean the surface to be painted using PPG
Industries DX330 Wax and Grease Remover or
equivalent (Xylene or M.E.K.).

Quicksilver’s Light Gray Primer.
5. Allow a minimum of 1 hour dry time and no more
than 1 week before applying the finish coat.
6. Apply the finish coat using Quicksilver’s EDP
Propeller Black.
GEAR HOUSINGS
The following procedures should be used in refinish-
ing gear housings. This procedure will provide the
most durable paint system available in the field. The
materials recommended are of high quality and
approximate marine requirements. The following
procedure will provide a repaint job that compares
with a properly applied factory paint finish. It is rec-
ommended that the listed materials be purchased
from a local Ditzler Automotive Finish Supply Outlet.
The minimum package quantity of each material
shown following is sufficient to refinish several gear
housings.
Procedure:
1. Wash gear housing with a muriatic acid base
cleaner to remove any type of marine growth,
and rinse with water, if necessary.
2. Wash gear housing with soap and water, then
rinse.
