The Outboard Boater's Handbook, Advanced Seamanship and Practical Skills

Creator: David R. Getchell | 1994-01-01

Batteries for electric motors are a different breed from those used in cars. While a car battery will not damage an electric outboard, ... You can also buy battery gauges that will tell you how much charge is left in your battery.

Publisher: International Marine/Ragged Mountain Press

About this book
This comprehensive manual shows you how to go places and do things you never thought possible in a small outboard motorboat. A well-designed ruggedly built 17-footer, for instance, can fish offshore, circumnavigate Lake Superior, and crisscross the continent on inland waterways or on a trailer pulled by the family car. Small outboards are among the most versatile boats ever developed and are far more able than you might expect. Covered here are all the popular types--and some exciting alternatives as well as methods that may change your entire boating outlook.Aided by contributions from other experts, veteran outboard skipper David R. Getchell, Sr., offers a wealth of useful facts and special savvy that reveal for the first time in a single book the true potential of these democratic boats 20 feet and under. Here are the means to understand what can be done, and the way to do it safely, including: how to judge a boat's potential and capabilities based on design and construction; how to rebuild an older boat; how to handle a little boat in big seas, surf, or shallow water; how to navigate; how to read the weather; how to head upriver or offshore; how to trailer your boat; how to manage and equip it for camp cruising on a nearby lake or for subarctic exploration; and how to care for the boat and motor.

    12 Volt battery Monitor

    Seemingly just another auto gadget fortunately the Equus 3721 is more sophisticated than its ponderous description. A breeze to connect to any car's 12 Volt electrical system. Simply push into the lighter socket or an auxiliary power outlet now found in many newer vehicles. With the engine running the instrument constantly displays battery condition with an LED light; amber when marginal, red if the battery is discharging. A green light indicates a correctly functioning electrical system. All is well with both battery and, most importantly, the alternator. The Equus is also an accurate voltmeter. Digital read-outs give exact voltage in the electrical system. Potential alternator problems or a failing battery will be indicated by below normal voltages, plus an amber or red light. Extra information is a battery icon graphically showing total battery charge. Tending towards erratic read-outs, and therefore unreliability, it is not the unit's best feature... 4/5 J. B. Syrett "Barry Syrett" (Gig Harbor, WA USA) - See all my reviews, April 16, 2008

    VERY GOOD FOR SUCH A LOW PRICE

    The Honda 2005 civic has a marginal charging system. This meter is ideal for determining when it is time to turn off the radio to reduce load on the alternator. Voltage reading is very accurate, much better than 1% as measured against a small Beckman pocket meter, which in turn has been checked against a Powerex Wizard aa cell charger. Warning lights function well.Some things to note when using this tester: Standard voltage of a 12 volt battery is 12.6 volts. Some deep cycle absorbed glass mat batteries will read 12.8. This is after loading the battery by turning on the headlights for 10 seconds, to remove surface charge. Note that while the lights are on, the voltage drops quickly at first, then the voltage stabilizes. Turning off the lights causes the voltage to rise again gradually. After a few minutes the voltage will stop rising. If the voltage settles at 12.6 (or 12.8 for AGM battery) battery is charged, assuming that the battery is near 68 degrees F.

    My research paid off -- this is great!

    My chrome wheels have begun to deteriorate: there's pitting/corrosion where the tire bead is, a common problem (I only recently learned) for those of us who live in places where roads must be heavily salted in the wintertime. So, the tires lose air annoyingly quickly. Because I'm not yet ready to purchase a new car & didn't want to spend $600+ on a new set of alloy wheels for my aging vehicle, a 12-volt compressor pump seemed like a good solution.Thanks to all the reviews -- good and bad -- found here on Amazon for a number of 12-v compressors, I decided to purchase this one. And I'm glad I did. It's speedy and plenty powerful for my needs; quieter, with less vibration, than what I was expecting. Love the compact size, a built-in gauge that's larger than some, and the hard-sided carrying case. If you're a newbie to the routine of inflating your own tires, don't be intimidated: this compressor is a breeze to use, you can easily tell when the valve connector locks onto... 5/5 Portia - See all my reviews Verified Purchase(What's this?)

    0 1/5 Robert LaFrance - See all my reviews Verified Purchase(What's this?) This review is from: 12 VOLT ELECTRIC AIR PUMP w/GAUGE for Tires Bikes Cars Air Matresses (Sports) I ordered this pump because of the great reviews. But when it came, I found the fittings to be poorly machined and it was slapped together with low-quality parts. The air pressure gauge is a joke.The icing on the cake was when I got an email from the seller promising me a FREE PUMP if I write a good review! Now I know where those good reviews came from! This form of bribery is certainly dishonest and probably illegal.Yeah, it pumps air. But so do a lot of other pumps that are cheaper and better quality. This is going straight to a garage sale and I'm buying a SLIME pump. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , November 4, 2012

    Perfect device at a great price

    I didn't have much in the way of expectations for this product, but I was quite impressed when it arrived shortly after placing my order on Amazon. I quickly discovered that the fuse to my cigarette lighter was blown. Moved it to the accessory jack and it lit right up. It comes with a fuse to protect it from damage, but at this price who cares?I had to use this in my girlfriend's car because she has been getting the battery light intermittently despite replacing the battery and alternator. This car has no volt meter in the dash, but with this gadget we get to see the voltage bounce between 13.8 and 14.2 consistently (which is quite normal.) This confirms that our specific problem is related to a short in one of the wires to the ECU.It is daylight readable, but not too bright at night. It has a warm blue glow and looks great in the dash. I would make it permanent if it was my car. With a good understanding of the properties of DC, this device could help... 5/5 G.

This review is from: Neewer® Mini 12V/24V LED Display Digital Car Volt Meter Vehicle Voltage Gauge Like the title said, out of two, only one is properly working after a month's use, the other died with no apparent reason. I have no intention of returning the item as obviously because of cost and burden ratio.Anyway, when it works, it's amazing. You could diagnose "on the fly" your car's alternator, battery, and equipment load performance.What broke on the broken one? On the screen, most of the lighting legs are dead now.

    14 AWG should satisfy majority of installs

    As stated, this is not pure copper...it is copper clad aluminum (CCA). Cost is less, but that's because aluminum is cheaper and more resistive than copper. I work as an engineer for a power company. Lower voltage distribution power lines used to often be made from pure copper - however it is more cost effective to use aluminum or aluminum alloys... but since the resistance is greater for these wires, the wire gauge is increased - so you need thicker wires to accomplish the same thing...however this is more cost effective. Same theory applies here...it's not pure copper, so ideally - you should use bigger wire than what your application would require if pure copper was used.General rule for 16 AWG wire is to keep runs at 48' or less. Most runs aren't that long, so 16 AWG will even satisfy most short wire installs... having said that, if you purchase the 14 AWG CCA wire - I'd imagine runs of wire up to 50' would be acceptable.Some reasons to shop around... 3/5 F.

    Great air station, but keep the manual

    This compressor/inflator is very attractive. It is also lightweight and all the accessories with the exception of the charger store right on the unit.I have owned compressors and I have owned high volume inflators. However, I have not owned a unit that includes both functions, and none of my units have ever been cordless.Mounted on the front of the unit are three connectors for inflatables and balls. The high volume hose has a large connector and there is also a high volume adapter for pushing in the internal flap of some inflatables. On the front is an LED light for working in the dark.The digital dial is bright and easy to read both in daylight and at night, and it has a sleep mode to save battery life.Right out of the box, I see nothing but perks.THE OPERATIONOperating the pump was not intuitive.

    Died after one year

    UPDATE 3/23/11: Died. Simply won't work anymore. It's been charged, plugged in to the car accessory port, and the thing simply will not turn on. The digital readout just blinks. Very frustrating. So I guess the lesson here is: don't buy! Changed my 3-star review to 1-star to reflect the failure.Original review 2/2010: For whatever reason, I have amassed several portable air pumps over the years, apparently attempting to get the "best" one. I've decided there simply isn't one. This one is close, but suffers the same problem my other battery-operated pump had: it HAS to be charged for it to work, and for it to be charged, it must be plugged into a wall socket for a number of hours. Adding to this is that the unit comes with a cigarette-adapter plug, which aids in powering the unit while running the unit (the other battery-operated unit need this too.) To fill all four car tires, it's pretty much a necessity to make use of the adapter.Operation is... 1/5 Personal Robot (Always here, sometimes there) - See all my reviews, February 18, 2010

    Nice compact portable inflator

    I have been using Black & Deckers ASI300 Air Station for over a year and can safely say that the ASI500 is a much better product. The one marked area of improvement is that the ASI500 is cordless. No more need to drag an extension cord around the car. After reading through the manual, and using the ASI500's digital pressure gage, I checked the tire pressure on one tire. After some trial and error, I was able to go through setting the recommended shut off pressure on the digital gage and inflated our van's tires. I was able to test the claim Black & Decker make about being able to fill four tires on one charge. Without charging, and using only the out of the box factory charge, this was accomplish leaving very little power to spare. I'm guessing that after a full charge the claim would be easily achieved. The ASI500 air station is very compact and easy to carry around. It has all the accessories for car, truck, bicycle, air mattress and all the sports balls.

This review is from: Roadpro 12V Battery Clip-On and Cigarette Lighter Adapter (Automotive) I bought this to use with a Vivair air compressor that draws about 15A. It will work off some accessory sockets, my bimmer works for instance, but not for very long without the engine running. In my truck, the amp draw is high for the accessory socket and it is only active with the engine running. This is a bit of a pain when you want to check and air up your tires. So I clip this to the battery terminals and I am good to go. The clips are not huge but work fine for me and the construction overall is fine. It is nothing very fancy but it is well worth the modest price IMHO. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , May 20, 2010

    Cable fell apart on first use

    I bought this cable to go along with the viair 85P portable air compressor, that way I didn't blow fuses.As soon as I opened the cable, I noticed it was only a couple feet long, which is not very long, but I was happy anyway.. The clamps also don't open up far enough to connect to a battery terminal securely.I took it outside and plugged it up to my compressor, popped the hood of my car and as soon as I opened the clamp the positive wire fell out of the clamp.Once I inspected the wire and the clamp, you could clearly see there was almost NO solder on the wire, and what little bit was on it was a "cold joint". The cable was also not crimped to the clamp like it was suppose to be (it looks like someone forgot to crimp it) , which is another reason it came apart.I went ahead and pulled the sleeve off the negative clamp and noticed it WAS crimped (unlike the positive clamp), but the solder was also very little and cold-jointed... 2/5 GlockMan - See all my reviews Verified Purchase(What's this?)
