2. Spring Boat Preparation
Batteries: Chargers, Alternators, and Voltages
Connections
Sealants
Boat Hull Speed
Mapping Your Hull
Bilge Pumps
Tanks
Hoses and clamps
Air Conditioning and Other Mechanical Systems
3. Batteries
Battery Voltages
12 Volt
High- 15.2v
Float-13.4v
Low-11.3v

24 Volt 4. High-30.4v 5. Float-26.8v 6. Low-22.6v 7. Check with specificGravity Meter 8. Check with Load Tester 9. 8 year life on Golf Cart Batteries 10. 10 Year life on L16 Batteries 11. 3 to 5 Years on Good Wet Batteries 12. 6 Years on Glassmat Batteries

Alternators
Check Alternator Output
13.8 Volts best
14.2 is Good but will cause batteries to expel gases
Need to Check Water Level More Often
Alternators can run through a charge divider
But always expect a one volt drop
Alternators Biggest cause of Battery over charging
13. Chargers
Charging and multiple banks of batteries
Charger should be hooked to largest draw on boat which is usually house bank
Best way to charge multiple banks of batteries is either multiple battery chargers or battery combiners
14. Connections
Check Batteries for Crystallized build up between Battery terminal and cable
Scrape with knife and wire brush clean
With baking soda and water, Flush terminal ends
Pull on wire lugs at fuses, breakers, terminals, and bus bars
Check all Molex and quick disconnect junctions
Rampage connectors, lures bonding, and mid 1990s cabo
15. Sealants
5200 final bedding sealant polyurethane
101 or Polysulfide
Silicone 1-2-3
Dolphinite
Hurricane Putty
Teflon Tape, Teflon paste
Lock tight 243
16. Boat Hull Speed
Square Root of Hull Length at water line (x) 1.34
Most Efficient speed for your boat
Give your Boat a diet
Weight placement
17. Mapping Your Hull
Make a detailed map of the Hull
Bilge pumps and High water alarms
Electrical pumps and motors
Autopilot pump, compass and feedback
Lighting
Safety equipment
Electronics and transdeucers
Inverters, Chargers, Batteries, Alternators, Generators, and Combiners
18. Bilge Pumps
Check Bilge pumps, float switches, and hose clamps
Bring wet dry vacuum
Bilges are collection depots make sure all hoses are clear
Check bilges for fishing, wire, tie wraps, insulations, and etc.
19. Tanks
Check all Aluminum Tanks for seams and welds
Look for cracks and fractures
Check all fittings for weeping
If theyre water tanks or waste tanks, check hose clamps
Check senders connections for corrosion
Check hoses for cracking and ferrel condition
Hydro carbons and oil cause premature hose failure
20. Air Conditioning
Check for deterioration on cooling hoses and clamps
Check for external corrosion on compressor
Have a technician run acid through cooling coils to remove marine growth and check Freon levels
21. Mechanical Systems
On mechanical systems
Check all hose clamps on engines
Check all hoses for cracks or failure
Look at wires attached to senders, solenoids, starters, and alternators
Check generator output with A.C. volt/hertz meter
Check alternator output on generator
Check belts raw water and impellers and ware plates
Insurance companies successfully deny claims for improper maintenance of these items
22. 23. 24. 25. 26. 27. 28. Bonding/Grounding Systems
Check bonding with a simple volt meter
Set meter to DCMV 600 to 850 MV
Check with specially designed meters for testing bonding systems (MIW sells these)
Ohm meter is simple to use in checking for connection between bonded material
Anode
Cathode
Electrode
Hydrogen Imbrittlement
Sodium Hydroxide
Crevice Corrosion
29. Shallow Water Anchoring Techniques
First, find your fish marks on sounder
Determine current
Determine wind direction
Established anchoring deployment speed
Use sounder to equate the distance you need to travel past your marking to properly deploy anchor
Keep in mind scope of anchor rode and bait carry rate
30. 31. Reading and Understanding a Fish Finder
Equipment (Video Fish Finder and Transducer)
Differences in Fish Finders
Differences in Power Outputs
Transducer Frequencies
Refresh Rate of Screen
Depth and Cone Angles
Definition at Different Frequencies
Description Sample Views of Sounder
