Corrosion CAUSE prevented, permanently

8-year guarantee, warranty and diagnostic support,

8-year free guarantee, warranty and (link) diagnosis support:  We will either prevent all the stray current that is the ONLY CAUSE of marine electrolysis corrosion or pay you back your purchase cost of SeaBis Master. How to Prevent Corrosion must be complied with. Guarantee here.

Proof we are genuine: Australian business law is strict. This website and SeaBis are owned by my company Podean Electronic Industries Pty Ltd. The Australian Business Number is 27008191848. Click here.


Photographic proof the SeaBis Master System with How to Prevent Corrosion will prevent corrosion.

The first photo is of Utopiall hull on the hard (slip) before SeaBis installed.  Therefore, see the corrosion causing hull to dissolve.

The second and third photos are a year submerged, after SeaBis Master System prevented the causes. Therefore, see no hull corrosion.  After that, antifouling works as designed.

In addition, none are caused by galvanic (nearly touching different metals) corrosion.

Examples are a stainless-steel ladder leaning against an aluminium hull.  Stainless-steel knob on aluminium cupboard. Easily prevented. Contact us.

When SeaBis Master System prevents ALL the CAUSES, there MAY remain galvanic corrosion at 3% of total.  Galvanic corrosion is easily prevented when electrolysis at 97% is prevented FIRST.  In conclusion, we will advise you.

Marine electrolysis corrosion 100% CAUSE is ONLY stray current. Therefore, prevent stray current, permanently – in 3 easy steps. Introduction.

Few pretty pictures.  Just the hard facts.  Most use ONE  SeaBis  Master only, made portable by fitting with battery clips, to completely prevent all *permanent CAUSE/s of stray current that is the ONLY cause of corrosion. Guaranteed.


* SeaBis may be made portable by fitting battery clips:

One SeaBis Master with battery clips can be moved battery bank to battery bank or boat to boat. All wires, including Current Sense, – green/yellow, may be extended hundreds of meters.  Note: * SeaBis indicates current on the circuit it is connected to.  Therefore, not on battery banks while moved elsewhere – connected elsewhere. Intermittent or new causes MAY occur while connected elsewhere, so require permanent installation *.

Also: the number of battery banks being monitored by SeaBis Master may be increased by using Battery Switches “Both” or “Emergency”. So paralleling battery banks.  *** ONE SeaBis Master will monitor them all. ***


Step 1 of 3.  

Identify the types of corrosion SeaBis Master System prevents.  From the photos in the above carousel.

All CAUSES are prevented by SeaBis Master System. Permanently.

The button is full size photo is Royal Albatross.  She is an old Tanker hull.  Similarly, proof that age does not cause electrolysis.

Step 2 of 3.  

Understand the CAUSE:

Wherever there is a battery (batteries must be DC) or Direct Current (DC) supply and current leakage to the Earth, stray current flows.  Above all, stray current is the ONLY cause of marine electrolysis corrosion.

External proof:  Wikipedia electrolysis.  Wikipedia specifically states DC – battery power.  NOT AC – shore power.

Therefore, when we prevent the DC that is the ONLY CAUSE of stray current, we prevent the corrosion. That is why we 100% succeed. Guarantee.

Step 3 of 3. 

Prevent the CAUSE. Permanently:

Marine Electrolysis Corrosion Prevention Procedure:

Install SeaBis Master:

Connect to battery power:

  • Brown to battery positive
  • Blue to battery negative
  • Green / yellow to metal hull or metal engine body
SeaBis Master System prevents the CAUSE of electrolysis corrosion.

ALL Battery positive indications – contact us immediately. Especially if you have both 12 and 24 volts. Fire risk can be eliminated.

SeaBis Master LED’s explanation:

In addition, your work is reduced by half:  SeaBis indicates battery side with fault.  “Battery positive” or “Battery negative”.

1:  Normal, either (green) = the stray current is far below corrosive threshold.  It cannot cause corrosion
2:  Caution (amber) = very low current, very slight risk
3:  Serious (red) = visible corrosion in 6 months
4: Critical (flashing red) = visible corrosion in 3 months
5:  AC Only (flashing red) = your batteries, electronics and yourself are at risk.  Excessive AC (110/240) on top of DC (battery). Common cause is power supply Active, Neutral or Earth reversed so your life is at risk.

All battery positive LEDs then contact us immediately.  There is a fire risk that can be prevented.

After that, observe SeaBis indicators:

  1. For instance, if you see other than either Normal (green) then the stray current is ongoing.  In addition, SeaBis Master indicates the side of the battery causing stray current. Therefore, halving your work. According to Bat + or Bat – indicator: Switch off or disconnect circuits on battery positive OR negative until you have a Normal.  Above all, when either Normal is On there is no stray current
  2. The last circuit you switched off was a cause of stray current
  3. Consequentially, leave it switched Off
  4. After that, to determine if there are any other causes, touch connect the remainder, one at a time
  5. Then, any that cause other than Normal, leave switched Off.  Reconnect all that indicate Normal
  6. In conclusion, you will have one or more circuits off / disconnected.  After that, see what has no power, and you will know the cause/s.

To prevent the CAUSE of stray current:
Follow How to Prevent Corrosion instructions or Contact Us.

Above all, now there can be no stray current, so no marine electrolysis corrosion, permanently.

 Proof that marine electrolysis corrosion is ONLY CAUSED by stray current – DC or battery power.  Never AC or shore power:

  1:  External proof by Wikipedia:  Battery power – Direct Current (DC) is the ONLY cause of stray current corrosion. Via air and water. In addition, look at the colour of power leads to apparatus. Red is DC positive and black is DC negative. Proof HERE.
  2:  In addition, do not waste your money, a Blocker, is in the AC power supply, so will not stop stray current corrosion. It will increase the risk of electrocution and allow corrosion to escalate: DC is the ONLY cause of stray current.  Reason: DC cannot exist in AC (shore or inverter power). Explanation HERE.
 3: Similarly, external proof by yourself:  AC (shore power) in DC:  Read the specification on your electric kettle / pot / hotplate / mains power appliance. There will be no DC entry. Therefore, it has no DC tolerance. In conclusion, IF there were DC in the AC, there is no Counter Motive current (Back EMF) therefore the appliance would attempt to draw infinite current. It would burn out in a few seconds.  Additional proof explanation Counter Motive Force (Back EMF) HERE.

IF there is DC in the AC, then SeaBis Master will indicate it by flashing red.

  4:  In addition, it is far lower cost to prevent stray current corrosion than repair:

“I had no marine electrolysis corrosion until a few weeks ago” – solution follows:

Solution: As the metal becomes rougher, so its surface area increases. That increases the stray current flow. Therefore, increasing corrosion, cumulatively. I have witnessed a 10-day time period from no to extreme corrosion far too many times. In many instances, two of US$5,000 propellers were corroded beyond repair in 10 days. Therefore, employ SeaBis Master System with How to Prevent Corrosion. Prevent the stray current that is the ONLY cause, NOW
5: In conclusion, if you cannot prevent the CAUSE, then CONTACT US, and we will support you – free.

Before SeaBis Master System:

Marine electrolysis corrosion is ongoing.  It is ONLY caused by stray current.  It causes metal to dissolve, therefore the coating bubbles.   In conclusion, ALL metal, everywhere onboard, conducts the stray current. Via air and water. After that, it attacks everything it has access to. Via water and air: propeller, gearbox, engine, hull, deck rails, mast and cross trees – all metal.
Hull dissolves
Before SeaBis. Hull dissolve. Therefore, antifouling lifts. Marine electrolysis corrosion prevention would have prevented the only CAUSE - stray current. Permanently.

After SeaBis Master System:

Marine electrolysis corrosion prevented.  Permanently.  Above all, no stray current therefore, no metal dissolved. Therefore, no bubbles.  Antifouling can work as designed.  No growth. 
In addition, no additional coating, plating, through hull or moving parts.
Above all, Antifouling can now work as designed. 
In conclusion, SeaBis Master System prevents ALL marine electrolysis corrosion. Permanently.
After SeaBis. Antifouling works as designed.
After SeaBis. A year submerged. Marine electrolysis corrosion prevention identifies then prevents the stray current that is the only CAUSE. Permanently. Antifouling works as designed.
After SeaBis. No stray currents. Antifouling works as designed.
After SeaBis. Underwater view. A year submerged. Marine electrolysis corrosion prevention stops ALL stray current. Antifouling works as designed.

Real life movie follows.  Made, to say thank you, by the yacht Owner:

An extremely complex commercial yacht.  In conclusion, ALL causes of marine electrolysis corrosion are prevented. Permanently.
In addition, most vessels need only one SeaBis Master.

Galvanic Corrosion is the remaining 3% :

There is only ONE cause for galvanic corrosion:    That cause is differing metals such as Aluminium and Stainless Steel that are touching or very close to touching in another than dry environment.  There is no other cause of galvanic corrosion.  Permanently.

Marine electrolysis corrosion accelerates galvanic corrosion on at least a 1,000:1 ratio.

Therefore, must be prevented BEFORE preventing galvanic corrosion.  After that, galvanic corrosion is easy to prevent by insulation, separation or anode.

For instance:  Leaning a stainless-steel ladder against the hull of an aluminium vessel will generate galvanic corrosion that dissolves the hull.  At the point, the ladder touches the aluminium.  Similarly, stainless steel handles on an aluminium cupboard will cause the aluminium to dissolve. Insulating the stainless steel from aluminium, at the point of contact, will prevent the CAUSE of galvanic corrosion. Marine electrolysis corrosion must be prevented first.

In conclusion, we will assist for a minimum of 8 years – free.

First, prevent the stray current that is the ONLY cause of at least 97% of marine electrolysis corrosion.  After that, prevent the 3% galvanic corrosion.  Corrosion causes will recur, therefore, we will provide free diagnostic support for a minimum of 8 years.
