  • Page 22: Casting Off And Approaching The Dock

    Chapter 3: General Information Casting Off and Approaching The Dock Unlike an automobile, the stern of your boat reacts first when turning. A turn to the right will swing the stern to the left and vice-versa. Remember that turning your boat away from an object, such as a dock, will tend to swing the stern toward that object.
  • Page 23: Towing

    Chapter 3: General Information Towing In the event of a mishap or power loss you may need to tow a boat or be towed. You should not tow a boat larger than your own. Always use safety and good judgment when towing. Never tow a boat if you are not equipped with the proper lines.

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 28: 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 29: 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.
  • Page 30: Throttle/Shift Controls

    Chapter 4: performance Throttle/Shift Controls The throttle/shift controls located at the helm station control the flow of fuel to the engine. They also act as gear shift levers to control the forward and reverse thrust of the propellers. The middle position of the throttle control is the neutral position. Move the control forward to engage the shifting mechanism which creates a forward thrust of the propeller.
  • Page 31 Chapter 4: performance Reverse the shift mechanism to stop a boat that is moving forward. This change in direction will provide a “braking action” and slow the boat. C A U T I O N The braking action causes a wake which may wash over the transom and flood the boat if the vessel is moving too fast.

    Chapter 6: Maintenance and Service NOTE: Do not steam press or dry in an electric or gas dryer. This will damage the canvas fabric. Water repellent was applied to your canvas during manufacturing. The repellent may have diminished after extended cleaning. Re-treatment of the fabric is recommended after extended cleaning.
  • Page 41: Scuppers

    Chapter 6: Maintenance and Service 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 periodically to make sure they are free of debris.
  • Page 42: Fuel System

    Chapter 6: Maintenance and Service Give special attention to the upper tubes of a hardtop or T-top frame. The area just below the top is shielded by the canvas or fiberglass top and does not receive the natural rinse that rainwater provides.

    Chapter 6: Maintenance and Service Fuel Tank Compartment The fuel tank compartments need 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.

    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. C A U T I O N Boats should not be lifted for storage using the bow and stern eyes.
  • Page 50: Cleaning And Lubricating

    Chapter 7: Winterization For outdoor storage, a canvas cover should be used to prevent “sweating”. 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.
