Fuel System
The 230BR is equipped with a single, 80 Gallon, pressurized fuel tank. The tank is of Polyethylene construction and is insulated with foam during
the construction of the boat. The tank is located on centerline between the aft livewell and aft end of the console. 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 pickups 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 under the leaning post.
There is an on deck fuel fill located on the port side of the boat, just forward of the console. Access to the fill is provided through an inspection
port. 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 230BR 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 system before starting the engine. This should be done after
service or after long periods of downtime for the boat.
All components of the 230BR 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.
When refueling the 230BR, whether on trailer or at a marina, the pressurized system will prevent overfilling. During fueling, check to ensure air is
escaping from the tank vent on the starboard side. 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.
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, however it is important to note that fuel senders
do not account for this. Therefore, filling the tank to 100 Gallons will not indicate “Full” on the gauge. When using your boat, it is a good practice
to keep a log and a running count of how much fuel you’ve used. Do not rely on the fuel gauge exclusively as variations will occur.
