You better announce to the dock master you are putting this type of
electrolisis on your boat.

This could initiate electrolisis and anodic reaction to most other boats
around you and dock and dock hardware and cause them to be the "sacrifical"
part in this corrisive situation.

If you add electrolisis, then all the anodes surrounding your boat will
attract those superfluous emissions and prematurely erode all the anodes.


Also, be careful with painting props for obvious reasons. Half way through
next motoring season when a shaft bearing fails due to introduced
unballanced wear on them, you can be assured that its cause is directly
related to your painting a balanced part therefore making it unbalanced and
causing vibrations and failing bearings or seals. Keep the prop ballanced.

It is not electrolysis I'm fighting, it is shellfish.


Let's try again. The link says:

The application of pulsed electric fields to water containing micro- or
macro-organisms has been proven to be a means of controlling the
population of these organism, or to stun them over a certain electric
field dependent time interval. The fact that the efficiency of this
control mechanism increases with decreasing pulse duration opens the
possibility to utilize microsecond pulse power technology for biofouling
prevention in cooling water systems. The advantages over other techniques
used for biofouling prevention such as its independence from chemicals,
the fact that it is possible to stun, rather than kill unwanted biofouling
species, that it does not generate shock waves which could affect the
structure of the cooling system, and that it can be installed like a
filter in front of an existing cooling system, without requiring any
changes in the cooling system, make the pulsed electric field technology
(PEFT) a strong contender to existing biofouling prevention methods. A
recent field study, where tidal water from the Elizabeth River in Norfolk,
VA, was treated by means of the pulsed electric field method, demonstrated
complete prevention of biofouling in pipes when the river water at the
intake of the pipes was exposed to electric field of 6.5 kV/cm with 770
nanosecond pulse duration. The efficiency was 1,400 gallons of treated
water per kWh, an increase in efficiency by more than a factor of three
compared to results presented at the 1996 Zebra Mussel Conference.
Experiments with even lower electric fields and correspondingly lower
energy consumption are under way. modeling results indicate that
efficiencies of more than 50,00 gallons/ kWh may be reached in fresh water
cooling systems.



The livestock fence shocker delivers said pulsed electric field of
required intensity. If the electric pulse is monophasic it delivers net
charge into the water, creating electrolysis. If the electric pulse is
biphasic (ie: capacitively coupled) it will deliver no net charge into the
water, avoiding electrolysis.

I, know, I know. It's not livestock that are giving your propellor
problems and the article only mentions zebra mussels in 1996.

But then you are the guy who wrapped electrical connections in tape for
frequently flooded aircraft runways and buried them in the ground, despite
the law saying those connections should be above ground in a hermetic box.
How many died because of that?

With barnacle growth the size of a medium shopping trolley fouling your
drive train at least you have the electrolysis problem solved as there are
no exposed metals to electrolyze.

I have studied this in depth at university in Bangalore.
