Brunswick Corp. has lowered its guidance for the fiscal year to a range of $1.20 to $1.35 per diluted share from continuing operations due to lower production of marine products in the second half of 2007 as a result of continued weakness in retail markets in the U.S. Previously, the company had estimated diluted earnings per share from continuing operations of $1.65 to $2.00 for 2007. The company expects Q2 diluted earnings per share of 64 cents to 65 cents.
