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.

    Looked Boring...But Then I Plugged It In

    This car charger with two USB ports had me mystified initially. When you look at it first taking it out of the box, it looks like very ordinary looking USB charger with two ports. But I found it to be much more than that.Let me give you the whole shebang and you'll see what I'm talking about:+ It includes two USB ports. Even though our car has had a USB hub already with three USB ports, it is very rare that we use more than one at a time... And at the maximum we used to. So this one seems to have more of an ideal configuration for us. Without the third USB port we save some space.+ When plugged in to your car cigarette lighter, it features a blue digital display. That display includes:... Internal temperature... voltage... AmpsThese metrics are more than just fluff. If you have owned a wide spectrum of electronic devices from different manufacturers, you'll know how important amperage is. Android phones tend to... 4/5 PositiveLogic (Somewhere along Pacific Coast Highway) - See all my reviews, March 10, 2015

    LED display is excellent as are the USB charging features

    Very high quality product. LED display is excellent as are the USB charging features. Battery volt meter is also a very nice to have feature for many cars. Having all these features crammed into such a small well built device make this a very unique almost must have product. Product cycles between - car battery voltage, interior temperature, and USB charging amps.As for the USB charging - I load tested the USB ports and it does meet the specs exactly as described. This is important because many other products I've bought that are similar do not actually perform as claimed. Having the correct USB charging amps is especially important if you want to charge or use higher load devices like tablets while on the go. As others have noted the thermometer is on the inside and the electronics of its own display heat it up a little causing a slightly off reading..

    Cable is excellent, it's just what I needed & would buy this exact same cable again. My poor review is for the person cutting the cable. They did not use, or did not care, or missed the class in grade school on how to read a measuring device, or just sent me what was left on each spool of red & black cable.I needed two 5' pieces of red #2 & two 5' pieces of black #2 to redo my battery cables & snow plow cables on my plow truck. I ordered the cable & other items needed to complete this job back in the beginning of September 2015 & I'm now getting started on this project at the end of October 2015, before the snow starts to fly at the end of Nov. or Dec.I rolled out this excellent cable to cut it into the four 5' pieces needed to do the job & to my surprise I can not complete it until I buy another 5' piece of #2 Red cable.
