Maintenance Cobia advises owners that maintenance and repairs should be performed at an authorized Cobia Dealer. The following information is general in nature and should not be considered a repair manual or guidelines set forth by Maverick Boat Group. Cleaning Each Cobia boat is constructed using the finest materials and components available.
DO NOT operate the boat if the engine stop switch system does not function properly. Go to a Cobia Dealer to have this resolved immediately. The lanyard should be securely attached to the boat operator at all times that the engine is on.
Yamaha engine owner’s manual located in the Cobia Duffel Bag. Cobia Duffel Bag Along with your boat, you received a Duffel Bag with your new Cobia. Inside the Duffel Bag are the following items: o Large Livewell Standpipe o Short Livewell Standpipe o 1.5”...
If there appears to be an excessive amount of water, the filter component should be replaced. See your authorized Cobia Dealer for replacement parts. Refer to Fuel System diagram, page 38.
Bilge Bilge The bilge of your Cobia should always be checked before and after a launch. While checking the bilge, note that a small amount of water in the bilge is normal. However, a large amount of water or any signs of fuel or oil requires immediate attention.
until you feel it snap back in place. Once this is completed you can try to turn the pump on again. If the bilge pump still does not turn on, it likely needs to be replaced. It is not recommended to use your boat if the bilge pump and/or float switch are not functioning properly.

Battery Switch and Main Distribution Panel Battery Switch and Main Distribution Panel The battery switches and main distribution panel are located on the inboard wall of the helm station. The battery switches are labeled to correspond with each battery and the component it powers.
Ladder & Props Stainless Boarding Ladder This Cobia model comes standard with a telescoping stainless-steel boarding ladder integrated into the port aft platform area. This provides a stepping area while the ladder is in the up position. Once the ladder is down and in the extended position, close the lid cover for safe and secure entry and exit via the ladder.
Props Prop selection on your Cobia is determined by your local Cobia Dealer, but all props are based on recommendations from Cobia Boat Company and Yamaha Marine in order to give your boat maximum overall performance. The needs of your prop will determine the prop design and size that best fits your performance requirements.
Continuous or periodic running of the automatic bilge pump may be an indication of a hose leak or break in a seal and should be investigated by a Cobia Dealer immediately. Refer to page 10 for further information regarding bilge pump operation and maintenance.
The livewell operates by pumping fresh seawater from the pump through an aerator head into the livewell. Drainage is achieved through the grate on the top of the standpipe, which, when unobstructed, will limit the water level to the standpipe’s highest point.
Windshield The windshield on the 280 DC can fold to either fit in either an open or closed position. The open position allows for an easy walkway to and from the bow, while if it is closed it can sit securely for long runs.

Bench Seats & Ski Box Aft Bench Seat The Cobia 280 DC has an innovative aft bench which can be positioned two different ways. In the compact position, the seat leaves more room on the deck by resting the bottom cushion in a vertical position. While in this position, the transom is made more easily accessible.

Cooler Bench Seat Your Cobia 280 DC comes equipped with a versatile and easy to use adjusting cooler seat. It can be positioned to provide a front facing seat or a reclined back facing seat. The position of the seat can be changed by simply by moving the backrest opposite the direction you would like to face.
An electric head with macerator unit is standard on the 280. The instruction manual can be found in the Cobia Duffel Bag, and basic operating instructions are listed on the following pages. (Refer to page 35 for Sanitation System diagram).

This is the position the handle should be kept in at all times to prevent the possibility of mistakenly discharging waste overboard in waters illegally. (Within 3 miles of shore and where otherwise designated.) If desired, the handle can be locked in this position by inserting a padlock through the hole on the handle and through the housing on the Y- valve.

Note that the wide portion of the handle is covering the down arrow. The exposed arrows show the direction of the flow up. FLOW UP = DECK PUMPOUT Note that the wide portion of the handle is covering the up arrow.
A bow plate and anchor roller have been added to accept the anchor and keep it far enough from the bow of your 280 DC to prevent damage to the bow. The windlass is mounted just aft of the bow roller plate.

Please review the manufacturer’s operating instructions on the following pages before using your windlass. Additional information can be found in the Lewmar owner’s manual. WARNING: READ ALL INSTRUCTIONS BEFORE OPERATING WINDLASS DO NOT USE THE WINDLASS TO DRAG THE BOAT TO YOUR ANCHOR. THE PROPER METHOD IS TO USE YOUR BOATS OWN POWER TO POSITION YOURSELF RIGHT ABOVE THE ANCHOR AND THEN USE THE WINDLASS TO HAUL THE ANCHOR.
