Page 3: Fuel System
Fuel System The 239DFS is equipped with a single, 100 Gallon, pressurized fuel tank. The tank is of aluminum construction and is secured/insulated with foam during the construction of the boat. The tank is located on centerline between the livewell and aft end of the Fishbox/Ski Locker. There is a sending unit installed in the tank. Inspection ports in the deck and head compartment provide access to tank fittings. There is a fuel pickup installed in the tank. The pickup incorporates a shut off valve along with an anti‐siphon valve than can be accessed through the in deck inspection plate, adjacent to the convenience center. There is an on deck fuel fill located on the port side of the boat, outboard of the windshield and adjacent to the passenger console door. The tank vents through an EPA Carbon Canister, located in the anchor locker, which than vents overboard through a vent fitting on the starboard side of the hull. Access to the vent is provided through an inspection port. It is recommended that these connections be inspected annually. The 239DFS will come pre‐rigged from the factory with an engine matched Fuel Water Separator. The fuel water separator is installed in the bilge and accessed through the bilge access hatch located in the engine pod. The Fuel Water separator should be checked periodically to ensure the fuel is free of water. Fuel should be disposed of in an approved waste collection device when servicing/replacing. The filter must be filled with fuel after servicing/replacing them in order to prime the engine. A primer bulb for the engine is located in the engine pod. It is used to prime the engine and system before starting the engine. This should be done after service or after periods of downtime for the boat. When refueling the 239DFS, whether on trailer or at a marina, the pressurized system will prevent overfilling. Any blockage of the vent, vent line and/or orifice line will prematurely trigger the shut off on the fuel nozzle and will prevent you from filling the tank completely. It is recommended to inspect your fuel system annually to ensure that all hose fittings are secured and the lines are free of any kinks. All components of the 239DFS Fuel System are approved for use with ethanol blended fuels up to 10%. E85 fuel should never be used. Key West recommends using non ethanol fuels whenever possible to reduce the risk of moisture retention in the fuel system, especially in areas of high heat/humidity. Due to the emission requirements of the EPA, certified fuel tanks and systems will not fill to the top of the tank. Instead, there will be a ullage in the top 10% of the tank. The specified capacity of the tank (100 Gallons) accounts for this ullage when the tank is static and level. Therefore, it is important to make sure the boat is as level as possible when filling the tank. Any forward or aft tilt will cause fuel to collect in one end of the tank and prematurely reach either the forward or aft tank vent. When fuel reaches these vents, it triggers the shut off. When the boat is level, fuel will reach these vents at the same time and allow the maximum quantity of fuel into the tank. The tanks ullage will also affect your fuel gauge as the tanks sending unit will not reach the top of the tank, even when the tank is filled. This will cause the fuel guage to not read full, even though it is. Do not rely on the fuel gauge exclusively as variations will occur. The stated capacity of the 239DFS tank DOES NOT reflect the quantity of usable fuel in the tank. The tank and its pickup are designed to allow as much fuel to be used as possible when on plane or in the boat’s level floating position, but it will not allow all fuel to be used. When using your boat, it is a good practice to keep a log and a running count of how much fuel you’ve used. -
Page 5: Raw Water System
Raw Water System The 239DFS features a raw water system for the transom livewell and raw water washdown system. Raw Water Supply The 239DFS features a single high speed venturi pickup for raw water intake. The pickup incorporates a seacock. Before using the boat, it is important to note the location of the seacocks and the means to achieve access to them. In the event of a rupture in a raw water line or pump that allows unrestricted flow of water into the bilge, shutting the seacock will be critical. Seacocks should be checked periodically and the valves moved to verify operation and unrestricted movement. If problems are found, they should be addressed immediately by your dealer. Livewell System There is one 800GPH livewell pump. It is mounted directly to the seacock. The pump provides raw water to the transom livewell. The pump has an independent switch and circuit breaker (See Electrical Schematics). To use the livewell, it is important to check and verify that the seacock is open. Failure to open the seacock may result in pump failure if the pump is run dry for an extended period of time. The livewell pump is a centrifugal pump that is not pressure regulated. Therefore, it is recommended that the pump only be used when using the livewell. The pump is self‐priming. Before activating the pump, make sure the livewell fill valve is open and than switch on the pump. It is important to check the livewell pump annually and periodically spray it/them with a corrosion inhibitor. Raw Water Washdown System The 239DFS features a standard raw water washdown system. The system is fed by a pump that is located under the convenience center sink. The pump is controlled by a switch and circuit breaker (See Electrical Schematics). Water is supplied to the pump off of the accessory port on the livewell pump(lower hose connection on the livewell pump). Using the raw water washdown does not require the livewell pump to be on, however the seacock must be open. Failure to open the seacock may result in pump failure/damage if the pump is run dry for an extended period of time. The raw water pump features an in‐line strainer for collecting any debris that could damage the pump. The strainer should be checked periodically. If you are using the boat in “dirty” water on a regular basis, it is recommended the strainer be checked routinely. The strainer features a clear cap for easy inspection. If any debris is found, remove the strainer screen by untwisting the clear cap and clean the screen. The pump features a built in pressure regulator that will shut the pump off when pressure is achieved in the system. The raw water washdown faucet is located on the port side, adjacent to the transom bench seat. If trailering the boat or using the boat after an extended period of downtime, it will be necessary to prime the washdown pump. Before activating the pump, open the washdown faucet and than switch on the pump. When the system is free of air, you can either close the faucet or shut off... -
Page 7: Fresh Water System
Fresh Water System Fresh Water Supply Fresh water is stored in a 12 gallon tank located under the port transom bench seat. Access to the tank and tank fittings is achieved through the bilge access hatch located in the engine pod. The tank features a fill line, vent line and supply line. These fittings should be checked annually. It is critical that only potable water be used in the tank. Failure to do so may require overhaul of the entire freshwater system. Fresh Water Fill and Vent The fresh water tank is filled from a fill deck plate marked “WATER”. It is located on the port swim platform, directly forward of the engine well. Before filling the tank, verify the quality of the water and make sure area around the fill is free of containments that could enter the tank. While filling, verify the tank is venting through the tank vent which is located in the splash well. An absence of air escaping from the vent may indicate a blockage or kink in the vent line. This will result in the tank failing to fill all the way which will show in water flowing out of the fill well before coming out of the vent. It will also diminish the performance of the fresh water system as a blocked vent will create a vacuum in the tank as water is used, thereby resulting in less water to the pump, continuous cycling of the pump and loss of water pressure. This could ultimately result in damage to the pump. Check the vent line periodically to ensure there are no kinks or blocks. Washdown Pump The fresh water system is fed by a pump that is located under the convenience center sink. The pump is controlled by a switch and circuit breaker (See Electrical Schematics). Water is supplied to the pump from the tank outlet located on the bottom of the tank. The fresh water pump features an in‐line strainer for collecting any debris that could damage the pump. The strainer should be checked periodically and features a clear cap for easy inspection. If any debris is found, remove the strainer screen by untwisting the clear cap and clean the screen. The pump features a built in pressure regulator that will shut the pump off when pressure is achieved in the system. The 239DFS comes equipped with a fresh water faucet in the convenience center sink and a fresh water shower located on the port swim platform. An optional freshwater shower head can be installed in the passenger console. If the system has not been used for a period of time, it may be necessary to prime/bleed the system of any air. Before activating the pump, open the fresh water washdown faucet and then switch on the pump. When the system is free of air, you can either close the faucet or shut off the pump. It is important to check the washdown pump annually and periodically spray it with a corrosion inhibitor. System Operation and Maintainence Only use potable fresh water in the system. Always verify there is sufficient quantity of water in the tank before activating either the washdown or mister system. Insufficient water quantity will cause the pump to run dry and may lead to failure/damage. Before using the freshwater system for the first time on the water, fill the tank and cycle all the water out to ensure the tank is clean and free of containmainents. Afterwards check strainer(s) for debris and clean if necessary. -
Page 9: Drainage System
Drainage System General Overview All water in the 239DFS is drained either via gravity or pump. It is either drained directly overboard or to the aft bilge where it can be drained out either via the garboard drain plug or the bilge pump. It is important to check the drainage system frequently to verify water flows freely, hoses are secure and there are no leaks. The drains and discharge pump are as follows starting at the bow: Anchor Locker – Gravity drain along centerline of hull to aft bilge Center Bow Locker, Port Bow Locker and Passenger Console Sink Drain – Gravity drains, all connected via T‐Connectors to single drain to aft bilge Starboard Bow Locker – Gravity drain runs through starboard stringer to aft bilge Fishbox Lip Drain – Gravity drain through port stringer to aft bilge Fishbox Drain – Feeds directly to Fishbox Macerator Pump Fishbox Macerator Pump – Located under convenience center sink, discharges 1‐1/8” Thru Hull on transom (See Note A) Driver and Passenger Console Recess Drains – Gravity drains, drain directly to the bilge Convience Center Sink Drain– Gravity drain to aft bilge Ski Locker Drain – Gravity drain, connects via T‐Connector to Convience Center Sink Drain Port Cockpit Drain – Gravity drain to port transom 1‐1/2” Thru Hull Starboard Cockpit Drain – Gravity drain to starboard inboard 1‐1/2” Thru Hull Port Transom Storage lockers– Gravity drain directly to aft bilge Transom Livewell Overflow Drain – Gravity drain connects via T‐Connector to Transom Livewell Drain Transom Livewell Drain –... - Page 10 Floor Drain Overview Two of the most important pieces of equipment on your 239DFS are the cockpit floor drains as their operation is integral to your safety on the water. At 1‐1/2” in diameter, they are designed to allow massive quantities of water to leave the cockpit of your boat in a very short period of time in the event of a swamping or extreme down flooding event. All the drains in your 239DFS operate this way, however, the floor drains are designed so that water can only flow in one direction; out of your boat. The drain features a unique design that acts like a check valve thereby preventing backflow of water into the cockpit of your boat. The design of the drain and its operation is solely dependent on the foam ball and seal ring. Any degradation in the foam will compromise the balls ability to seal against the seal ring. Therefore, do not apply power washers or any cleaning chemicals directly to the drain area as this will compromise the foam in the ball. When using chemical cleaners in your boats interior, use a sufficient quantity of water to dilute the chemical(s) when spraying off so that they do not affect the foam ball when draining out. The seal ring needs to be kept free of debris so that foam ball will seal flush. The drain features a grate so that debris cannot flow into the drain. In the event that a sufficient amount of debris collects around the seal, the grate and top of the drain assembly can be removed. Use a spanner wrench to unscrew the top of the drain and clean the drain assembly. This will also provide access to the foam ball which can than be removed and replaced if necessary. Only do this if it becomes evident that ball is not sealing properly. This will be manifested by small amounts of water coming through the drain when the boat is sitting at rest in the water. DO NOT remove the drain while the boat is in the water. Under normal conditions when Whenever the thru hulls are the thru hulls are above water, submerged below water, back the ball is below the seal ring pressure seals ball against seal ring, thereby allowing water to flow creating a watertight seal and out of the cockpit and prevents backflow of water from the overboard thru hulls.

Page 12: Electrical System
Electrical System General Overview The 239DFS is equipped with a standard 12V DC Electrical system. The 239DFS can only be rigged for a single motor. If the boat is rigged without an optional battery selector switch, the boat will be rigged for x1 Group 27 battery. If the battery selector switch is installed, the boat will be rigged for x2 Group 27 batteries. Key West recommends this option for those who wish to install an optional windlass to their boat due to the high power demand. The battery(s) will provide power to the engine, house and optional windlass system. All batteries and final electrical rigging will be performed by your dealer prior to delivery. Please consult with your dealer regarding the battery installation of your boat prior to taking delivery of your boat 12V power is distributed to the 12V factory installed systems through individual circuit breakers located beneath their respective switches on the main switch panel. All 12V systems are grounded individually to a grounding block located inside the console. The grounding block is than grounded directly to a battery. A 30amp main circuit breaker is installed adjacent to the batteries to protect the house systems from overload and is connected either directly to the batteries or the optional battery selector switch. Additional circuit breakers for the auto bilge pump and stereo memory are wired directly to either the battery or battery selector switch. If a windlass is installed, an additional 50amp circuit breaker will be installed. The system is designed so that turning the battery switch/switches off will still allow the bilge pump to function in an automatic mode. Key West recommends that boats that are going to be left in the water or in a boat lift, where access to the drain plug is not feasible, be installed with a battery charger to prevent discharge by the bilge pump. Trim Tabs and optional power steering are connected directly to the battery and feature overcurrent protection. They do not energize until the engine ignition switch is turned to the “On” position. Electrical System Maintenance All connections in the electrical harness feature deutsche connectors and heat shrink butt connectors to minimize corrosion. Key West recommends that all connections and terminals be checked at least twice a year and sprayed with a corrosion inhibiting spray at least once a year to protect and maintain the integrity of electrical connections. For troubleshooting purposes and further information, a schematic of the electrical harness is available for download in PDF on the 239DFS main page.
