1/General Information
1.1 General
The EdgeWater 145CC is a semi-custom fishing vessel designed to be powered by a single
outboard engine.
1.2 Owner / Operator Responsibilities
Registration
Registering your boat is important to you. Federal Law requires that all powered, undocumented
vessels be registered in their state of principal use. Contact the appropriate agency in your local
state to obtain specific registration information.
Reporting Boating Accidents
All boating accidents must be reported to the proper authorities in the state which the accident
occurred. If someone dies or disappears as a result of the recreational boating accident, it must
be reported immediately, with a formal report being made within 48 hours. If there is damage of
more than $500, or if the boat is completely lost, a formal report must be made within 10 days.
Questions regarding accidents may be directed to the Boating Safety Hotline, 800-368-5647.
Education
Whether or not you are an experienced boater, attending a Boating Education Course can be
beneficial. If you are inexperienced, it is the best, safest way to begin your life on the water. If you
are an experienced boater, it’s always good to sharpen your skills.
Required Equipment
The U.S. Coast Guard requires certain equipment on each boat. In addition, they also set
minimum equipment and safety standards. For more detailed requirement information, obtain
“Federal Requirements And Safety Tips For Recreational Boats”, by contacting the Boating Safety
Hotline,
800-368-5647.
Some states and local agencies require equipment that is not required by the U.S. Coast
Guard. Your local agency or dealer can provide specific information regarding these non-
standard requirements.

2/Helm Control Systems
2.1 General
The helm station is the control center for the boat. The main control systems are the engine
throttle/shift controls and the steering system. These provide the operator the ability to control
speed, direction, boat trim, and attitude. Each manufacturer provides manuals on the operation
and use of their systems.
2.2 Steering System
General
The manual which comes with your steering system provides specific information on your steering
system.
While running at slow speeds, most boats tend to wander slightly back and forth. Keeping the
wheel in the center without overcompensating for the slight wandering will prevent over steering
and reduce the tendency to wander.
Steering System Maintenance
Routine system inspection should occur regularly. Cables, linkage, and helm assemblies should
be inspected for wear, corrosion, cracking, or deterioration. Cleaning and light grease should be
applied to all exposed metal parts and other damaged or deteriorated parts should be replaced as
soon as possible.
2.3 Engine Throttle and Shift Controls
Refer to the engine manual supplied with your engine for specific information on your controls.
There are three major components of the engine throttle and shift controls: handles, throttle cable,
shift cable. Throttle and shift cables are push-pull and are connected to the fuel system
(carburetor or fuel injection) and the other to the shift rod linkage. By moving the handles forward
and back, the operator engages the cables thus controlling the amount of fuel being used and the
gear selector for forward, neutral and reverse. Careful use of the controls provides smooth,
responsive and safe operation.
Do not bring the throttle back abruptly to stop the boat unless it is an emergency. Allow
time for the engine RPM to come down to idle before shifting to reverse or severe gearbox
damage could occur. PLEASE REFER TO YOUR ENGINE OWNER’S MANUAL FOR
FURTHER OPERATIONAL PROCUDURES FOR YOUR OUTBOARD.

8
Engine Stop Switch
This device is designed to prevent the operator falling overboard while the engine remains
running. The engine stop switch lanyard should always be worn by the operator, while the boat is
in motion. Pulling the lanyard from the control will stop the engine. If the engine will not crank
properly, the lanyard may not be properly attached to the engine stop switch.
Do not use the engine stop switch to stop the boat unless it is an emergency as it may
impair your ability to quickly re-start the engine.
**NOTE** Each ignition key has a 3 digit number stamped on it. Please record this number
for future reference on the service information page in the front of this manual.
3/Propulsion System
3.1 General
Your new EdgeWater 145CC is designed to be powered by a single outboard motor. Most 2-
cycle outboards currently use an automatic system to mix the oil with the gasoline before the
engine uses it. On a 145CC equipped with a 2-cycle engine, the oil tank is maintained in the
crankcase. Make sure this tank always has a sufficient amount of the recommended 2-cycle oil for
your cruise, plus some reserve. 4-cycle engines require oil be maintained in the crankcase also.
Always check the crankcase oil level before each day’s run.
Always follow the manufacturer’s recommendations and use only the recommended oil
types.
Don’t attempt to service your outboard or any of its components unless you are
thoroughly familiar with its operation and dangers. Many of the moving part components
are exposed and can pose an extreme danger to anyone unfamiliar with their operation.
Always leave the servicing to a qualified technician.
Each manufacturer provides manuals designed to assist you in the proper operation and
maintenance of your new engine. Follow their guidance and schedules for proper operation of
your new engine. With a modern outboard there is little to do as long as proper maintenance is
performed, in accordance with the manufacturer’s recommendations. If the boat is to be kept in
saltwater for an extended period, electrolysis and marine growth can become a problem. When
leaving your boat in salt water overnight or for an extended period, tilt the engine as high out of
the water as possible. This will decrease the possibility of marine growth on the outside of the
engine, as well as reduce the potential of marine growth compromising the cooling water inlets in
the lower unit, which can cause overheating.
Do not paint your outboard’s lower unit with paints designed for boat hulls. Some can
cause severe damage to your engine. Check with your engine manufacturer to get their
recommendation.
Do not attempt control adjustments unless you are very familiar with their function, operation and
adjustment. Failure to properly adjust the system components can adversely affect your boat’s

9
performance and safety. Mis-adjustment can also cause severe control, engine or lower unit
damage.
Please return all warranty cards for boat, engine and other related items. This will assist
you in the event you have a warranty problem.
3.2 Engine Cooling System
Most outboard engines are cooled by water taken in through ports in the lower part of the drive
section. Make sure these ports are free of debris or other items that might cause the flow to be
restricted. Maintain a routine vigilance to see that the visual inspection streams have a steady
flow of water. If they do not, shut down the engine to see if they are clogged or if there is a more
serious problem. Be especially watchful if you have gone through an area of vegetation or
shallow water as the intake ports can become clogged with weeds, dirt or other debris.
Do not run your outboard without water coming into the lower unit. The water pump
impeller can be damaged in only seconds of this type of operation.
3.3 Propellers
A turning propeller moves the boat through the water, forward or backward. They should always
be clean and free from nicks or dings, which can adversely affect performance. Your dealer can
assist you in the proper selection of a propeller for your boat. This selection is based on the
horsepower of the engine and its relationship to the size and weight of the boat.
Propeller sizes are determined by two numbers, which appear on different propellers at various
locations. They are listed in sequence, for example 13 x 17. The first number is the diameter of
the propeller and the second is the pitch. Pitch is the theoretical distance the propeller moves
through the water with each complete revolution. The larger the number the greater the
theoretical movement. It also follows that the larger the number the greater horsepower is
required to turn it. With a load which is “normal”, or usual for your boating activities, the engine
should be able to reach its maximum operating RPM range at wide open throttle (WOT). With a
light load on smooth water, the engine should reach its manufacturer’s rated maximum operating
RPM at wide open throttle (WOT) and maximum trim. If it does not, you may have a propeller
which has too much pitch. If it goes beyond the maximum recommended RPM range, you may
have too little pitch. Neither condition is good for the engine. You will get shorter engine life and
poorer performance than your boat and motor were designed to provide.
If your boat came from the factory with a propeller selected by EdgeWater, it should
already be optimized for the performance of your boat. Before changing the pitch or
diameter of your propeller, always check with your dealer to determine how the changes
will affect your boat and engine performance. Certain modifications such as bottom paint or options
that affect weight balance and/or wind resistance may lower peak rpm. Always check with your
dealer first if optimum rpm can not be attained.
3.4 Engine Power Tilt and Trim
The power tilt and trim system on your outboard provides the ability to optimize the running angle
of your EdgeWater 145CC to allow for load and sea conditions. Moving the outboard lower unit

10
toward the transom is generally referred to as trimming “in”, while moving the outboard lower unit
away from the transom is referred to trimming “out”. It is generally best to have the engine
trimmed in for acceleration from displacement to planning mode. This brings the bow down and
requires less fuel and effort on the engine’s part to plane off the hull.
The first 20
o
of movement aft of the transom is referred to as trim and is the area generally used to
operate the boat while on plane. The area beyond the first 20
o
is referred to as tilt and is usually
reserved for operating in shallow water or pulling up on a beach.
While running under normal conditions, the bow should be in a 3
o
to 5
o
up angle to maximize the
hull’s ride and performance. When sea conditions are rougher than normal, bringing the bow
slightly down may improve the ride and will also allow the boat to remain on plane at a lower
speed.
Watch the hoses and cable on your engine as it is tilted to its full tilt position. They may
become caught and damaged if the engine is in the wrong position.
3.5 Engine Instrumentation
The following is presented to familiarize you with the instruments, which may be on your boat.
Every boat is not equipped with full instrumentation.
All factory installed Yamaha engines include Yamaha’s digital multifunction tachometer
and speedometer. Refer to your engine operators manual for use details.
Tachometer
The tachometer displays the number of revolutions per minute (RPM) the engine is turning. There
is a designed operation RPM range for the engine. Become familiar with the operating range of
your engine and its operating characteristics. The tachometers designed to aid the boater to
assure the engine performs within that designed range. The tachometer can be used to better
understand the performance of your engine and your EdgeWater 145CC. By monitoring your
tachometer as you operate your EdgeWater, you will find RPM ranges that work better in certain
sea and load conditions. Be alert the tachometer operation may provide an early indication of
difficulty, before it becomes irreversible.
Speedometer
The speedometer indicates the boat speed in miles per hour. Some types work using a spinning
wheel to determine the boat speed. Their accuracy can vary from the actual over the bottom
speed due to many factors. Other boat speedometers calculate the speed by amount of pressure
the moving water forces into a “pitot” tube. These gauges should only be used as indicators of
approximate speed and not used as absolute speed indicators. NOTE: All Yamaha
speedometers utilize a pitot tube. In the event that erroneous speed readings appear, it is likely
caused by debris clogging the pitot tube. Consult with your dealer on methods to clean the tube
and restore normal operation.
Temperature Gauge
This is designed to monitor the operating temperature of your engine’s cooling system. A sudden
rise from the normal should be investigated to determine if there is an obstruction in the cooling
system.
