New Yahoo (Nasdaq: YHOO) CEO Marissa Mayer appears to continue her housecleaning. U.S. sales chief Wayne Powers quit the search engine and media company Monday to become president of Parade Publications, the Sunday newspaper supplement published by privately held Advance Publications of New York.

Previously, Yahoo Interim CEO Ross Levinsohn quit on July 31, two weeks after the Sunnyvale, Calif., company recruited Mayer, 37,  from Google (Nasdaq: GOOG), the No. 1 search engine, where she had been Vice President for Local, Maps and Location Services as its third CEO in a year.

Levinsohn filled in after Scott Thompson was forced out in May during a proxy battle for a takeover of the company when it was discovered he had embellished his academic background in filings with the U.S. Securities and Exchange Commission.

Mayer last week named Ron Bell general counsel of the company.

Since Yahoo reported second-quarter results last month, Mayer said she wanted to conduct "a review process" of the company's plans that could lead to changes. The Yahoo board has been almost completely replaced since CEO Carl Bartz was fired last September and activist investor Third Point Capital won control of three board seats after mounting a proxy fight.

Yahoo shares fell a nickel to $14.98 in Monday midday trading, valuing the No. 3 search engine at $17.8 billion.
