CHANGING ENGINE OIL
Changing Oil Filter
1
Place a rag or towel below the oil filter to absorb any spilled oil.
2
Unscrew old filter by turning the filter to the left (a).
3
Clean the mounting base. Apply film of clean oil to filter gasket. Do not use
grease. Screw new filter on until gasket contacts base, then tighten 3/4 to 1
turn.
Oil Filling
4
Remove the oil fill cap (b) and add oil to proper operating level.
5
Idle engine for five minutes and check for leaks. Stop engine and check oil level
on dipstick. Add oil if necessary.

GEAR CASE LUBRICATION

When adding or changing gear case lubricant, visually check for the presence of
water in the lubricant. If water is present, it may have settled to the bottom and will
drain out prior to the lubricant, or it may be mixed with the lubricant, giving it a milky
colored appearance. If water is noticed, have the gear case checked by your
dealer. Water in the lubricant may result in premature bearing failure or, in freezing
temperatures, will turn to ice and damage the gear case.
Examine the gear case lubricant for metal particles. A small amount of metal filings
or fine metal particles indicates normal gear wear. An excessive amount of metal
filings or larger particles (chips) may indicate abnormal gear wear and should be
checked by an authorized dealer.
Draining Gear Case
1
Place outboard in a vertical operating position.
2
Place drain pan below outboard.
3

GEAR CASE LUBRICATION (CONTINUED)
Checking Lubricant Level and Filling Gear Case
1
Place outboard in a vertical operating position.
2
Remove the front vent plug (a) and rear vent plug (b).
3
Place lubricant tube (c) into the fill hole and add lubricant until it appears at the
front vent hole (d). At this time install the front vent plug and sealing washer (a).
4
Continue adding lubricant until it appears at the rear vent hole (e).
5
Stop adding lubricant. Install the rear vent plug and sealing washer (b) before
removing lubricant tube.
6
Remove lubricant tube and reinstall cleaned fill/drain plug and sealing washer (f).

SUBMERGED OUTBOARD

A submerged outboard will require service within a few hours by an authorized
dealer once the outboard is recovered from the water. This immediate attention by
a servicing dealer is necessary once the engine is exposed to the atmosphere to
minimize internal corrosion damage to the engine.

STORAGE PREPARATION

The major consideration in preparing your outboard for storage is to protect it from
rust, corrosion, and damage caused by freezing of trapped water.
The following storage procedures should be followed to prepare your outboard for
out-of-season storage or prolonged storage (two months or longer).
Never start or run your outboard (even momentarily) without water circu-
lating through the cooling water intake in the gear case to prevent dam-
age to the water pump (running dry) or overheating of the engine.

Fuel system
IMPORTANT: Gasoline containing alcohol (ethanol or methanol) can cause
a formation of acid during storage and can damage the fuel system. If the
gasoline being used contains alcohol, it is advisable to drain as much of the
remaining gasoline as possible from the fuel tank, remote fuel line, and
engine fuel system.
Fill the fuel system (tank, hoses, and engine fuel system) with treated (stabilized)
fuel to help prevent formation of varnish and gum. Proceed with following
instructions.
1. Portable Fuel Tank – Pour the required amount of Gasoline Stabilizer (follow
instructions on container) into fuel tank. Tip fuel tank back and forth to mix
stabilizer with the fuel.
2. Permanently Installed Fuel Tank – Pour the required amount of Gasoline
Stabilizer (follow instructions on container) into a separate container and mix
with approximately one quart (one liter) of gasoline. Pour this mixture into fuel
tank.
3. Place the outboard in water or connect flushing attachment for circulating
cooling water. Run the engine for ten minutes to allow treated fuel to fill the
engine fuel system.
