full tilt position. They may become caught and damaged if the engine is in the wrong position.
When tilting the engine is strongly suggested that the engine be aimed in the straight ahead position
to provide maximum clearance between the engine cowling and the splashwell.

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 tachometer is 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 225 EX . By monitoring your tachometer as you operate your EdgeWater,
you will find RPM ranges that work better in certain sea and load conditions. Careful monitoring of 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.
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.
Water Pressure Gauge
This gauge measures pressure in the engine cooling system. If the pressure changes from the norm it
could indicate a complete or partial blockage in the system or a water pump problem. If this does not
return to normal, your dealer should check it to make sure the cooling system is operating properly.
Fuel Gauge
This gauge indicates the amount of fuel in the fuel tank. It is always prudent to follow the “rule of thirds”,
