marine electrolysis
The SeaBis System is absolute. Compliance with ABYC Wiring Rules is achieved and proven. Detail available below:
The cause, under actual use conditions, is eliminated. Instantaneous proof is displayed by the

system.
Electrolysis is caused by electric current flowing through all metal in contact with any damp to immersed moisture (very slightly damp to immersed wet metal) such as engine cooling system, outboard legs, metal hull, propeller, keel to the sea bed. Electrolysis is used by manufacturing jewelers to deposit gold onto base metal. Your wet metal is being deposited on the sea bed. If you have any doubt then ask any jewelry manufacture "How do you deposit the gold plating?"
Electrolysis current causes all metal in contact with any water to be depleted to the sea / river bed. We measure the electric current through wet metal. The engine body, metal hell, propeller or keel, identify the cause then eliminate it. For Testimonials click here. There have been no guarantee claims with our 500+ vessels, all with money back guarantee, so we must be doing something correct..
Why does SeaBis provide a vast number of Testimonials with contact details when I can find no other that does?
Because the SeaBis System eliminates all electrolysis corrosion. Permanently. Testimonials here.
Why does SeaBis provide a 3 year money back guarantee when I can find no other that does?
Ask your supplier for a written guarantee. If they do not provide or it has an escape clause then there is a reason. "Blockers" connect in the shore power, earth wire. Electrolysis current is caused by battery power and flows from the damp / wet metal to the sea / river bed.
The SeaBis System Guarantee
After 500+ vessels with 100% success we confidently guarantee the SeaBis System will protect everything from the propeller on your fiberglass boat to the aluminum or steel of your hull from electrolysis (rust) corrosion. We have had no claims so must be doing something correct. Full guarantee here.
To understand how the SeaBis System eliminates electrolysis we need to understand electrolysis and it's cause.
Explain How SeaBis Works...
You are in your office or study. If the light above your head is turned on, then with the light still turned on you grab a rag and remove the lamp. The lamp goes out and electric current through the lamp ceases so the element does not deteriorate any further. The element is your engine / propeller / metal hull / keel. There is no point in measuring voltage (to the lamp), that has not changed. We measure current (through the lamp element) that causes electrolysis then eliminate it by using Process of Elimination instructions supplied with SeaBis.
Current from all metal that can get damp to wet, to the sea bed causes electrolysis corrosion. SeaBis measures that current, accurately, instantly and safely. We then unplug / disconnect equipment until SeaBis indicates Normal. Now follow Process of Elimination instructions supplied with SeaBis to eliminate the cause.
To prove the current path to the sea bed use SeaBis Flexible or Maintenance System with the probe in the water path to the sea bed. Proof will be instantaneous.
Electrolysis Corrosion Explained...
Electrolysis corrosion is caused by electrolytic action between damp to immersed metal and the sea or river bed. Electrolytic action is particles of metal being dissolved from the metal by battery (DC) electric current. Battery current is DC - Direct Current so always flows in the same direction. So dissolved particles will not be replaced as occurs with AC - Alternating Current. All electrolysis is eliminated by the SeaBis System under actual use conditions - guaranteed in writing here.

E-11 AC and DC ELECTRICAL SYSTEMS ON BOATS
Based on ABYC's assessment of the existing technology, and the problems associated with achieving the goals of this standard, ABYC recommends compliance with this standard for all systems and associated equipment manufactured and/or installed after July 31, 2004.
- 1. This reference is rock hard and definite. The Bonding or DC grounding conductor shall not be used as battery negative:
11.5.2.2. DC Grounding Systems and Bonding - A metallic hull, or the bonding and DC grounding systems, shall not be used as a return conductor. (See Figures 9A and 9 B, and Figures 10 A and 10 B, and E-11.18 DC Grounding and Bonding.)
- 2. This is reference rock hard and definite. The DC Grounding conductor must carry no current. Battery negative carries 80% of the battery positive:
Definitions – Continued, a conductor that is intentionally maintained at boat ground potential. DC grounding conductor - A normally non-current carrying conductor used to connect metallic non current carrying parts of direct current devices to the engine negative terminal, or its bus, for the purpose of minimizing stray current corrosion.
- 3. This reference is rock hard and definite. Battery negative must be insulated from engine and drive train:
11.16.4.2.2.3. The ungrounded battery cable shall be routed to avoid contact with any part of the engine or drive train.
- 4. This reference is rock hard and definite. Battery negative carries 80% of battery positive current so must be insulated:
11.17.2.1. Appliances and fixed DC electrical equipment shall be designed so that the current carrying parts of the device are insulated from all exposed electrically conductive parts.
- 5. This reference is rock hard and definite. Third wire! The battery negative is not to be used as DC grounding conductor.
11.18.2.2. Routing - The DC grounding conductor shall be routed from the device to the engine negative terminal or the DC main negative bus by one of the following means:
11.18.2.2.1. The DC grounding conductor shall be routed together with the current carrying conductors as a third wire;
11.18.2.2.2. The DC grounding conductor shall be routed as a separate conductor.
- 6. This reference creates confusion. I think this paragraph applies to all House equipment or small Outboard Engines only. Not larger engines or drive trains:
11.18.2.5. DC Grounding Bus
11.18.2.5.1. The DC grounding bus shall be connected directly to the engine negative terminal or the DC main negative bus.
- 7. This reference is rock hard and definite. The battery negative is not to be used as DC grounding conductor.
11.18.2.2.2. The DC grounding conductor shall be routed as a separate conductor.
- 8. Radio Ground Plate. We fit a special capacitor in series with the Tuner connection to the (metal) hull to stop battery negative on the Tuner metal body causing electrolysis The capacitor allows the Radio to work correctly (pass AC) and stops all DC.
11.18.2.7. Radio Ground Plate - If the radio ground plate is connected to the engine negative terminal, the connecting conductor shall meet the requirements of ABYC E-4, Lightning Protection, since a radio ground plate may also function as a lightning ground plate.
