How do you create an instance of phantomJS with a custom window.navigator object?

How can a custom window.navigator object be applied to PhantomJS's WebPage object during creation? When I attempt to customize the navigator, I'm still receiving the default value when I console.log('The default user agent is ' + page.settings.userAgent);

What I have so far:

console.log('hello');
var page = require('webpage').create();
page.onInitialized = function() {
  page.evaluate(function() {
    var newNavigator = Object.create(window.navigator);
    newNavigator.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36';
    window.navigator = newNavigator;
  });
};
page.open('http://www.google.com', function(status) {
  if (status !== 'success') {
    console.log('Unable to access network');
  } else {
console.log('The default user agent is ' + page.settings.userAgent);
}});

The contents of the console when running the above js:

hello
The default user agent is Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534.34
(KHTML, like Gecko) PhantomJS/1.9.7 Safari/534.34

You don't need and cannot use evaluate to set the navigator. You can just set via settings. So the following works for me on phantomjs 1.9.7:

page.onInitialized = function() {
    page.settings.userAgent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36';
};

Output

hello
The default user agent is Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36
