Electrical and electronics for trailer-boat made simple
TRAILER-BOAT MARINE ELECTRICAL AND ELECTRONICS YOU CAN FINALLY UNDERSTAND!
My fishing life started in small boats. I have been addicted to fishing all my life. Naturally small boats and fishing go together and it was after endlesss technical
questions that the fishing-book was born. I decided to write it in a clear and simple
format. Technology has also rapidly passed through the world of the small trailer-boat
fisherman and finding answers is not always easy. Do you want quality gear? West Marine- America's Favorite Boating Supply Source

What the reviewers are saying about the trailer-boat fishing book
He speaks our language.....If there was ever a book to make the marine electrical system
understandable, this is the book. If there was ever a book that will give every boat owner
more confidence about how things work, this is it. If there was ever a book you'll want to
carry with you on board, this is the one to have. Pat Piper Editor - BoatUS Trailering
Magazine
..helps small boat anglers better understand the installation, troubleshooting and repairs of
electrical systems such as trolling motors, downriggers, trim tabs, batteries, fishfinders
and charts Soundings Magazine
…”anyone considering purchasing devices and installing them on any size craft will find
this to be an indispensable reference.” “I highly recommend this book, and I would stick
it in the same box as my new chart plotting GPS” On The Water Magazine
Book Introduction
John Payne may speak with an accent but whatever he says, the words are easy to
understand. It's because he speaks the language every boat owner needs; clear and
accurate information presented in simple sentences. He is never ahead of the reader and
there aren't many people who are experts in marine electronics with that ability. Well,
John Payne is such a fellow.
As the Editor of the BoatU.S. Trailering Magazine, I am well aware of the need for
someone with practical hands-on experience who can speak to, rather than at boaters. Too many times, in too many books, a relatively simple solution to a boat's electrical trouble is lost forever in a sea of shoptalk and jargon that requires someone with an engineering degree to understand (I'm also convinced these are the same guys who write the "simple" directions to VCR and DVD operation).
The Fisherman's Electrical Manual is written for the person who wants to spend more
time on the water than trying to learn the meaning of a sentence he or she has just read. This is because John Payne spends a lot of his time giving standing room only seminars or having one-on-one conversations with boaters about problems they are having or about ways to make an electrical system more safe and efficient. He speaks our language. If there ever was a book to make the marine electrical system understandable, this is the book. If there ever was a book that will give every boat owner more confidence about how things work, this is it. If there ever was a book you'll want to carry with you on board, this is the one to have. Trailer boat owners and fishermen are going to be well-served by John Payne's common sense approach to "Anything Electric". This is a guy
who knows his stuff and, best of all, can explain it in an easy to understand manner.
Every reader of the Fisherman's Electrical Manual is going to become a more complete
boater as a result. And that's good for all of us. Pat Piper. Editor - BoatU.S. Trailering

THE OUTBOARD STARTER MOTOR
On the average trailer-boat the outboard engine starter motors are of the inertia type and drive the flywheel ring gear.
The starter motor develops the high torque that is required to turn over the engine against
the high cylinder compression. The most common causes of starter motor problems are
bad connections causing voltage drop. If the starter motor grinds over slowly or the
solenoid clicks away without any starter rotation, check the main positive and the
negative circuit connections. The main connections are those heavy cables that come
from the battery and terminate on the outboard engine. How much battery capacity is
required to start outboards? The answer is to install the outboard manufacturers'
minimum recommendation, and a good baseline is up to 50 HP - 450 CCA; up to 120 HP
- 500 CCA and up to 350 HP - 600 CCA. If you use the battery for other equipment then
you will have to factor that in to the capacity calculations. Refer to the battery chapters
for more on starting batteries, and battery ratings (CCA, Ah etc).
TROLLING MOTORS - How much thrust is required?
The general rule of thumb in choosing the required thrust is to take the total weight of the
loaded boat and divide it by 70. For example, if your trailer-boat with people and gear weighs a
total of 3500 lbs (1700 kg) you divide this by 70. That means that a motor with at least 50
lbs (215 kg) of thrust is required. Another method is 5 lbs thrust for every 200-350 lbs of
boat weight. Depending on your trailer-boat fishing the wind and current should be factored in. The
draft of a trailer-boat affects the drift rate, and shallow draft or high freeboard cabin type fishing
boats tend to have a greater wind (sail plane) effect than deeper draft low freeboard ones.
Where strong river or tidal flows will be involved greater thrust will be required.
ALL ABOUT ELECTRIC FISH and FISHING!
There are electricity producers such as electric eels with up to 600 volt outputs. How they
don't electrocute themselves is still being researched. Most fish have inherent electric
fields generated by the nervous system. Sharks and rays are renowned for their ability to
detect electrical fields and vibrations of their prey. Many other fish such as catfish, trout,
sturgeon and salmon have a lateral line on their flanks with electro-receptors, and some
have them on their heads. The electro-receptor nerve cells detect electrical fields and
vibrations which are used to detect concealed prey. The basis of electric fish attraction is
the use of various field strengths to attract fish. Research and testing has shown that some
fish are attracted by a small positive charge and repelled by a strong positive or negative
charge. Salmon can detect voltage variations as low as 0.025V. Fish can also transmit
electrical signals similar to sonar, and receive the reflected signal back.
HOW TO SELECT STARTING BATTERIES
The starting battery must be capable of delivering the outboard starter motor with
sufficient current to crank over and start the engine. This starting load can be increased
by engine compression, oil viscosity and engine driven loads. Loads such as a trolling
motor or anchor windlass under full load also require similar high values of current. The
starting battery is normally selected on the basis of the engine manufacturers'
recommendations. It is good practice to have a safety margin for multi-start capability.
Also allow for colder climates where more engine start current is required and as batteries
are less efficient when very cold.
WIRING - WHICH VOLTAGE TO USE?
In many fishing trailer-boat it is now becoming quite common to see boats having a primary 12
volt system and a 24 or 36 volt system for the trolling motor. The 12-volt system is the
most common system. This is because of automotive influences, and outboard engines
being made with 12 volt systems. The charge voltage is typically 14 volts. For 24 volt
systems the charge voltage required is 28 volts. Effectively where two voltages are used
they should be treated as two entirely separate systems. In polarised ground systems the
negatives will be connected to maintain the same potential. Because much equipment is
commonly 12 volts a DC-DC converter must be used to step down to 12-volts. The
alternative is to tap off the 12 volt supply from one of the series connected batteries. The
advantage of using a DC-DC converter does isolate sensitive electronics equipment from
the surge and spike-prone power system. Where 36 volts is used, three 12 volt battery
banks are connected in series to make 36 volts
WIRING - LIGHTNING AND SMALL TRAILER-BOATS
Like the golfer, the fisherman in a small trailer-boat out on a lake is exposed. Many fishermen
use graphite and titanium rods, and these are an ideal conductive "target". How far away
is the lightning? Time the lightning flash by counting the number of seconds to when the
thunder is heard. Divide this number of seconds by 7 to give the distance in kilometers.
Lightning consists of a number of components with charges exceeding 200,000 amperes
at over 30,000°C for a matter of milliseconds. The positively charged ions rise to the
cloud top, and the negative ions migrate to the cloud base. Regions of positive charged
ions also form at the cloud base. Eventually the cloud charge levels have sufficient
potential difference between ground and another cloud to discharge. The leader is a
negative stream of electrons consisting of many small forks that follow and break down
the air paths offering the least resistance. The upward positive leader charge rises some
150 yards (50 m) above the ground, and when the meet a channel is formed. The return
stroke is generally much brighter and travels upwards to the cloud partially equalizing the
potential difference between ground and cloud. In a matter of milliseconds after the
return stroke, another downwards charge takes place following the same path as the
stepped leader and return stroke.

ALL ABOUT U.S. BOAT TRAILER-BOAT WIRING
Trailer-boat lighting is critical and even known to ruin the best of fishing-trips when the police pull you over and issue a ticket. Most light fittings are vehicle types with incandescent lamps.
They are easily flooded and waterlogged, with resulting burnout and failure. The new
LED types have lower heat outputs and can be potted or sealed to reduce water ingress
when launching. There are a number of trailer-boat trailer wiring and plug/socket configurations. The
following are standard although you should check your own vehicle to be sure. In the 6
pin terminal plug/socket the center terminal is marked A, and is an auxiliary terminal and
is generally used for backup (reverse) lights. It is also used to supply +12 volts to charge
the breakaway switch battery, which is common with electric braking on the trailer. In the
7 pin terminal plug/socket 7 is the center terminal. (Wiring Tables are in the book)
Fishfinders - Do sounders and other acoustic noises scare the fish?
Absolutely! My work on a submarine sonar program showed me how noisy the sea and
any body of water can be, full of environmental and biological sound sources. Whales
and dolphins communicate using acoustics, the latter along with porpoise use sonar to
hunt. Seals and catfish use their whiskers to detect acoustic activity of their prey. A fish
has a series of receptors located along the lateral line, which is comprised of an array of
sensory cells and nerve endings. Every acoustic noise generated is detected by the fish on
these cells, and this includes the acoustic noise generated by fish as they swim. This is
caused by water displacement and creation of small ripples or turbulence. Crustaceans
and mollusks also create noise and that is their downfall as fish locate them. Many fish
also know when predators are in the area from the acoustic noise they create. Lure
makers now concentrate on adding acoustic effects that mimic natural prey, such as
vibrating plugs, poppers and rattle lures, and these along with special flies are used in
night fishing. Different fish will have different thresholds of perception. Any fish will
have adapted to the ambient or background noise of the habitat, and any unusual or
abnormal noise that is not consistent will be detected. Sounder noise tends to be
directional and the closer the fish is to the source, the greater the impact. Assume that
sounder is detected, and decide when set up on location whether you will switch the
sounder off. If it doesn't affect your fishing then stay as you are, but if you are fishing the
tournaments then everything counts. Boat noise includes the sound of an approaching
trailer-boat which will produce noise from the outboard motor and the propeller noise signature
and cavitation, wash which is affected by hull form, chines and boat speed. The propeller
noise signature is also affected by small blade and tip damage. Noise from inside the boat
is also a major factor, and this is about onboard low noise practices and discipline. The
pro tournament fishermen soundproof the trailer-boat and keep noise to an absolute minimum.
Noise sources also come from bait pumps and bilge pumps, all which may cause
vibration and noise on the trailer-boat hull, so they must be carefully mounted on shock absorbent
mounts. You have to "run silent" the same as submarines do. Trolling motors are also a
source of noise. When the motor is switched on there is momentary partial cavitation and
vibration created by water bubble or cavity formation due to pressure reduction at the rear,
tips and faces of the propeller blades. Bearings also create noise and Minn Kota use
special bearing systems in trolling motors to reduce noise outputs. A constantly running
trolling motor may not spook fish, however sudden large speed increases alter the
ambient noise levels with a higher noise output. Are you looking for a new fishfinder? Go to

What is DSC VHF radio?
The saltwater trailer-boat fisherman who ventures offshore will be looking at the introduction of
Digital Selective Calling (DSC) VHF radios. I have a Standard Horizon model on my
boat. These are part of the Global Maritime Distress and Safety System or GMDSS.
Channel 70 is reserved for DSC use. DSC has the advantage that digital signals in radio
communications are more efficient than voice transmissions, as well as significantly
faster. A DSC VHF transmission typically takes around a second to broadcast boat details
and precise position. A dedicated DSC watch receiver is required to continuously monitor
the specified DSC distress frequency. Class D controllers are now available, and these are
from Standard Horizon, Raymarine, ICS, Icom and Simrad. DSC radios enable the
transmission of digital information based on four priority groupings, which are Distress,
Urgency, Safety, and Routine. To perform this selective transmission and reception of
messages, every station must possess what is called a Maritime Mobile Selective-call
Identity Code (MMSI). The DSC Distress alert message is configured to contain the
transmitting vessel identity (the MMSI code or Unique Identifier Number), the time, the
nature of the distress, and the vessel position where interfaced with a GPS. After
transmission of a distress alert, it is repeated a few seconds later to ensure that the
transmission is successfully transmitted
