8. Connect the steering and shift cables.
9. Shift and steer the unit through the entire range and check for any binding or stiffness. Correct adjustments as necessary.
10. Shift to forward position and check that the reverse gate is not preloaded. You should be able to slightly rock the reverse gate
up and down. Excessive play requires shift cable adjustment.
11. Check that the bottom edge of the reverse gate is above the outside diameter of the rudder. If the reverse gate is below the
outer diameter of the rudder, do not operate the boat. See an authorized Mercury Marine dealer for proper adjustment.
IMPORTANT: Adjust the shift cable so that the reverse gate does not interfere with water flow coming out of the rudder. If
the reverse gate is hanging in the water flow, a strong vibration may be felt in the control box and failure of the forward stop
or other components will result.
Submerged Power Package
A submerged power package requires prompt service by an authorized dealer after recovery. This immediate attention 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).
NOTICE
Without sufficient cooling water, the engine, the water pump, and other components will overheat and suffer damage. Provide
a sufficient supply of water to the water inlets during operation.
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, fuel pumps, and fuel injection systems) with treated (stabilized) fuel to help prevent formation of
varnish and gum. Proceed with the following instructions.
1. Portable fuel tank ‑ Pour the required amount of Quicksilver Gasoline Stabilizer (follow instructions on container) into the fuel
tank. Tip the fuel tank back and forth to mix stabilizer with the fuel.
2. Permanently installed fuel tank ‑ Pour the required amount of Quicksilver Gasoline Stabilizer (follow instructions on container)
into a separate container and mix with approximately 1 liter (1 US quart) of gasoline. Pour this mixture into the fuel tank.
