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.

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 175CC / 155CC. 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.
Temperature Gauge
This is designed to monitor the operating temperature of your engines 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, one-third of the tank to get the destination, one-third to return, and one-third in reserve.
This gauge is a measure of relative fuel supply and is not a calibrated instrument!
