6.4 Ethanol-blended Fuel
Ethanol is an oxygenated hydrocarbon compound that has a high octane rating, therefore it is useful in
increasing the octane level of unleaded gasoline.
6.4.1 Additives
World Cat exclusively powers every new boat with Yamaha Outboards. Under its Maintenance Matters
program, Yamaha recommends the following additives be used to maintain your new outboard at top
performance: Yamalube Fuel Stabilizer & Conditioner to protect against the damaging effects of today’s
ethanol fuels and Yamalube Ring Free to prevent carbon buildup.
See your Yamaha owner’s manual and your authorized Yamaha dealer for more detailed maintenance instructions.
6.5 Electrical System
The electrical system on your catamaran consists of three major components: the battery system, wiring and
circuit protection, and accessories. It is important that you understand the principles of the electrical system so
that you can protect the components and troubleshoot any problems you experience.
6.5.1 Battery System
The World Cat 255DC is equipped with two G roup 27 batteries. Both batteries are dedicated as “cranking
batteries”. The starboard battery also acts as your house battery.
NOTICE
The use of improper gasoline or additives can damage your fuel system and is considered mis-use of
the system. Damage caused by improper gasoline or additives WILL NOT be covered under warranty.
!!! DANGER
Disconnect the battery cables from the batteries prior to removing or working on the battery
management panel. Failure to do so could result in electric shock. Reference the NMMA pamphlet in
your Owner’s Portfolio for more information.
!!! DANGER
All batteries contain an electrolyte, commonly sulfuric acid, which is a caustic and volatile chemical.
Use extreme caution when charging or servicing.
6.5.3 Emergency Parallel
In the event of a battery failure, the combine function of the battery switch allows you to mechanically
link the port “cranking” battery to the starboard engine or vice versa.
6.5.2 Battery Distribution
Your World Cat is equipped with a Dual Circuit Battery Switch, a “DC MAIN” breaker and four constant hot
breakers. Turn the Dual Circuit Battery Switch clockwise to the “ON” position to power on both port and
starboard batteries. If you experience low voltage and need more power to crank the outboards you can
utilize both engines by turning the Dual Circuit Battery Switch clockwise to the “COMBINED” position.
The Dual Circuit Battery Switch MUST be turned back to the “ON” position once the engines have cranked.
The “DC MAIN” breaker will receive power only when the Dual Circuit Battery Switch is on the “ON”
or “COMBINED” position. The other four breakers will remain active
regardless of the Dual Circuit Battery Switch position. Per NMMA and
USCG guidelines, these breakers are constantly energized to provide power
for bilge pumps, memory functions and additional accessories. Inspect the
breakers regularly. If a breaker trips frequently have your dealer investigate
the problem as soon as possible to prevent damage to your boat.
