6.4 Ethanol-blended Fuel
Ethanol is an oxygenated hydrocarbon compound that has a high octane rang, therefore it is useful in
increasing the octane level of unleaded gasoline.
6.4.1 Addives
Phase separaon occurs when water enters a tank that contains an ethanol / gasoline blended fuel. When
gasoline becomes saturated, a mixture of ethanol and water, known as phase separaon, can form in the
tank, in the form of two layers: an upper ethanol-decit gasoline layer and a lower ethanol-rich water layer.
This may cause knocking in an engine running on the gasoline layer, while the engine will not run at all on
the ethanol / water layer.
While it is impossible to absolutely guarantee avoidance of phase separaon, there are a few preventave
steps that could help. Installing a 10-micron fuel / water separang lter in the fuel line between your fuel
tank and your outboard lters the gas and allows any water (which is heavier than gas) to safely sink to the
boom of the lter and out of the fuel.
Adding a quality marine-specic non-alcohol-based fuel stabilizer and condioner (like Yamalube
®
Fuel
Stabilizer & Condioner PLUS) to each tank can also help. Before proceeding with any steps, please rst
consult with an authorized servicer of your brand of outboard.
If phase separaon does occur, your only remedy is to drain your fuel tanks, clean and dry the tank
completely and rell with fresh fuel.
6.5 Electrical System
The electrical system on your catamaran consists of three major components: the baery wiring system, the
component wiring system with circuit protecon, 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.
6.6 Baery System
Your World Cat is equipped with three standard baeries. Two addional baeries are oponal, depending
on accessories. Two of the baeries are Type 27 “cranking baeries”; the third is a Type 31 “house” baery.
The two cranking baeries each control one engine and provide the inial current to start the engines. The
house baery controls all other electrical components on the boat. The two oponal baeries are Type 31
house baeries and control only those opons.
To help maintain your baeries, a management system is installed on your boat, beneath the helm seat.
This system, controlled by a panel similar to the one shown below, enables you to engage or disengage
the baeries, distribute electrical current, and parallel baeries in the event of a failure. Chapter 10 of this
manual will provide details regarding the locaon and wiring of your baeries and management panel.
6.6.1 Baery Distribuon
The distribuon panel controls the ow of current from the baeries to the
engines and on-board funcons through three main switches. Each switch is red
and labeled ‘Port Start’, ‘STBD Start’, and ‘House’.There are two yellow parallel
switches labeled ‘Emerg Parallel’.The house components are protected by an
80 amp breaker labeled ‘DC Main 1’. When leaving the boat, all switches should
be turned to the “OFF” posion, while the DC Main breaker can remain on.
NOTICE
The use of improper gasoline or addives can damage your fuel system and is considered mis-use of
the system. Damage caused by improper gasoline or addives WILL NOT be covered under warranty.
