It is important to note, during any maintenance procedure replacement fasteners must have the same measurements and strength as those removed. Numbers on the heads of the metric bolts and on the surfaces of metric nuts indicate their strength. American bolts use radial lines for this purpose, while most American nuts do not have strength markings.

Page 27: Storage Preparations
MAINTENANCE Storage Preparations 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.
-
Page 28: Positioning Outboard For Storage
MAINTENANCE Positioning Outboard for Storage Store outboard in an upright position to allow water to drain out of outboard. CAUTION If outboard is stored tilted up in freezing temperature, trapped cooling water or rain water that may have entered the propeller exhaust outlet in the gearcase could freeze and cause damage to the outboard.

30% relative humidity, at 25 C (77 F) temperature and a barometric pressure of 29.61 inches of mercury. Summer conditions of high temperature, low barometric pressure and high humidity all combine to reduce the engine power.
-
Page 32: Boat
GENERAL INFORMATION Due to the horsepower/RPM characteristics of an engine, this will result in further loss of horsepower at the propeller with another decrease in boat speed. This secondary loss, however, can be regained by switching to a smaller pitch propeller that allows the engine to again run at recommended RPM.
-
Page 33: Engine
GENERAL INFORMATION CAVITATION Cavitation is caused by water vapor bubbles forming either from a sharp edge or angle on the gear case or from an irregularity in the propeller blade itself. These vapor bubbles flow back and collapse when striking the surface of the propeller blade resulting in the erosion of the propeller blade surface.
-

5. Pour alcohol into carburetor throats (alcohol will absorbed water). Again rotate flywheel. 6. Turn engine over and pour alcohol into spark plug openings and rotate flywheel. 7. Turn engine over (place spark plug openings down) and pour engine oil into throat of carburetors while rotating flywheel to distribute oil throughout crankcase.

(steering effort equal in both directions) without causing the propeller to break loose. Refer to Mercury Precision Parts/Quicksilver Accessory Guide for a complete list of available propellers. 1. Select a propeller that will allow the engine to operate at or near the top of the recommended full throttle RPM range (refer to Section 1A — Specifications preceding) with a normal load.

Page 36: Propeller Removal/Installation
GENERAL INFORMATION Propeller Removal/Installation WARNING If the propeller shaft is rotated while the engine is in gear, there is the possibility that the engine will crank over and start. To prevent this type of accidental engine starting and possible serious injury caused from being struck by a rotating propeller, always shift outboard to neutral position and remove spark plug leads when you are servicing the propeller.

GENERAL INFORMATION 6. Install forward thrust hub, propeller, rear thrust hub and propeller nut onto the shaft. Forward thrust hub Propeller Rear thrust hub Propeller nut 7. Place a block of wood between gear case and propeller and tighten propeller nut. -
Page 38: Compression Check
15% or compression for both cylinders is less than 685kPa (100psi), the powerhead should be disassembled and inspected. 6. Compression check is important because an engine with low or uneven compression cannot be tuned successfully to give peak performance. It is essential, therefore, that improper compression be corrected before proceeding with an engine tuneup.

Page 143: Oxides Of Nitrogen — Nox
EMISSIONS Oxides of Nitrogen — NOx NOx is a slightly different byproduct of combustion. Nitrogen is one of the elements that makes up the air going into the engine. Under extremely high temperatures it combines with oxygen to form oxides of nitrogen (NOx). This happens in the engine’s combustion chambers when temperatures are too high.
-
Page 144: Stratified Vs. Homogenized Charge
EMISSIONS Stratified vs. Homogenized Charge DFI engines use a stratified charge inside the combustion chamber to aid in reducing emissions. All other models use a homogenized charge. The difference between the two Homogenized Charge A homogenized charge has the fuel/air particles mixed evenly throughout the cylinder. This mixing occurs inside the carburetor venturi, reed blocks and crankcase.
-
Page 145: Stratified Charge
EMISSIONS Stratified Charge A stratified charge engine only pulls air through the transfer system. The fuel required for combustion is forced into the cylinder through an injector placed in the top of the cylinder (head). The injector sprays a fuel/air mixture in the form of a bubble into the cylinder. Surrounding this bubble is air supplied by the transfer system.
