Some of these factors are listed below. Reference the trouble- shooting guide on page 75 in Sportfish, Cruisers, Yachts Owner’s Manual for additional suggestions on adjusting performance.

  • Page 30: Propeller

    Chapter 4: performance Propeller The condition of your prop has a major influence on the performance of your boat. Your engine(s) should be equipped with the best size prop for normal conditions. Unusual uses or weight conditions may require special props. A damaged prop can affect your boat’s top speed, cause vibrations, create a sudden drop in RPMs or even increase fuel consumption.

  • Page 31: Steering

    Chapter 4: performance WARNING Do not attempt to service any engine or drive component without being totally familiar with the safe and proper service procedures. Certain moving parts are exposed and can be dangerous. CAUTION Do not paint the outboard motors with anti-fouling paints designed for boat hulls. Many of these paints can cause severe damage to the engines.

    Chapter 5: Instrumentation Digital Electric Steering (DES) The DES package uses an electric actuator to steer each engine. The Digital Steering Helm and Digital Electric Control send signals to the engine and Steering Control Unit (SCU), which control the operation of the electric steering actuator(s) on the engine(s). The SCU receives signals from the steering actuator position sensors and the Boat Control Units (BCUs) to carry out steering and joystick (if equipped) operation.

  • Page 37: Switch Panel

    Chapter 5: Instrumentation On the joystick are five control selector buttons. The Joystick selector activates the joystick. The throttle and joystick must be in the neutral (center) position for this selector to be activated. The joystick controls the side to side and rotational movement of the vessel. The operator is the central pivot point around which the boat moves and the further one moves the joystick, the greater the thrust and speed in that direction.

  • Page 42: Finish/Waxing

    Chapter 6: Maintenance and Service Finish/Waxing Gel-coat will age or dull naturally due to constant exposure to the natural environment and pollutants. Discolorations are shallow in depth. Factors that will affect the rate of discoloration are: the sun, pollution, old wax accumulation, and the salt content of water. Polishing compound (fine abrasive) or rubbing compound (coarse abrasive) is recommended for use on fiberglass finishes to remove scratches and stains or restore severely weathered surfaces.

  • Page 43: Bottom Paint

    Chapter 6: Maintenance and Service W A R N I N G M.E.K.P. (Methyl ethyl ketone peroxide), gel-coat and acetone are flammable and hazardous chemicals that must be handled properly. Follow instructions carefully. After the gel-coat is catalyzed, it will soon heat up and put off fumes. When finished with catalyzed chemicals, or if they start to build up heat, submerse completely in water until cool.

  • Page 44: Snaps And Zippers

    Scuppers Grady-White boats have self-bailing cockpits meaning water on the cockpit floor drains by gravity through large aft scuppers and not into the bilge. The aft drains (scuppers) have an external scupper flap assembly that restricts the flow of water back into the boat. Inspect the flaps...

  • Page 45: Seachest

    Chapter 6: Maintenance and Service In addition to inspecting the scuppers, annually inspect the hoses and replace if necessary. To inspect hose, observe water flow between the cockpit and the thru-hull. If water flow seems restricted, a high pressure water hose can be used to flush debris from the scupper hose. If water leaks into the hull interior from the hose or fittings, replace these components immediately before using the boat.

  • Page 46: Fuel System

    Chapter 6: Maintenance and Service Both painted and anodized aluminum parts must be washed periodically with a very mild soap and water solution. Grady-White recommends washing with a mild soap (such as Ivory Liquid) ® after each use and every two to three weeks if stored in an outside marine environment. Strong cleaners and soaps must not be used.

  • Page 51: Fuel Tank Compartment

    Chapter 6: Maintenance and Service Fuel Tank Compartment The fuel tank compartment needs to be rinsed periodically especially when used in a salt-water environment. Dirt accumulation attracts salt, creating salt crystals. Salt crystals can corrode most metal surfaces if left untreated over a period of time. To help protect your fuel tank from corrosion, rinse the compartment with fresh water.

  • Page 52: Inverter Batteries

    Chapter 6: Maintenance and Service • Keep battery terminals clean by scrubbing them with a stiff brush and a mixture of baking soda and water. Afterwards, apply a light coat of grease or corrosion preventative. • Batteries should be secured in the trays installed to minimize movement when the boat is in use.

  • Page 57: Chapter 7: Winterization And Storage

    Manual for a checklist on winterizing and storage. Boat Storage Grady-White boats are equipped with stern eyes and a bow eye. These eyes are for anchoring and trailering purposes, and should be inspected regularly to insure structural integrity. Eyes that are severally corroded or bent should be replaced.

  • Page 58: Cleaning And Lubricating

    Chapter 7: Winterization For outdoor storage, the boat may be shrink wrapped, or protected with a properly fitted canvas cover. The cover should be fastened securely so that winds cannot remove it or cause it to chafe the boat. A poor covering job will eventually cost more than the price of a well-made cover. C A U T I O N Boats covered with plastic shrink wrap during storage must leave the fuel vent fitting outside of the enclosure to prevent the trapping of dangerous fumes.

  • Page 59: Batteries

    If you have developed any vibrations during the season, look for loose engine bolts, bent shafts or bent propellers. Engine Flushing System The Canyon 456 is equipped with a Reverso Engine Flushing System. To properly winterize this system, antifreeze must be pumped through for 8 minutes. Fuel System The fuel systems should be winterized by following the fuel system maintenance and fuel tank compartment instructions in the maintenance and service section.

  • Page 60: Getting Boat Out After Storage

    Chapter 7: Winterization Getting Boat Out After Storage Before placing your boat in the water for the boating season, have the hull bottom sanded and reapply anti-fouling bottom paint if necessary. Leave as much equipment and personal effects as possible off the boat until after launch and final check. Prior To Launching Start your own personalized list of items to check and perform prior to placing your boat in the water.
