     This Amendment No. 5 (this "Amendment") is to the
Solicitation/Recommendation Statement on Schedule 14D-9, as amended (the
"Schedule 14D-9"), that relates to the offer by OMC Acquisition Corp., a
Delaware corporation (the "Offeror") and a wholly-owned subsidiary of Detroit
Diesel Corporation, a Delaware corporation ("DDC"), disclosed in a Tender Offer
Statement on Schedule 14D-1 dated July 15, 1997, as amended (the "Schedule
14D-1"), to purchase 13,842,619 shares of Common Stock, par value $0.15 per
share (the "Shares"), of Outboard Marine Corporation, a Delaware corporation
(the "Company"), at a purchase price of $16.00 per Share, net to the seller in
cash, without interest, upon the terms and subject to the conditions set forth
in the Offeror's Offer to Purchase and in the related Letter of Transmittal each
dated July 15, 1997 (which, together with any amendments or supplements thereto,
collectively constitute the "Offer").
    
 
     The item numbers and responses thereto below are in accordance with the
requirements of Schedule 14D-9. The information set forth under each item below
