Gentlemen and Ladies:

     We have acted as counsel to Power Investments, Inc., an Indiana
corporation, Franklin Power Products, Inc., an Indiana corporation,
International Fuel Systems, Inc., an Indiana corporation, Marine Corporation of
America, Inc., an Indiana corporation, Marine Drive Systems Inc., a New Jersey
Corporation and Powrbilt Products, Inc., a Texas Corporation (such companies,

Additional Notes are to be issued pursuant to the terms of an Indenture
substantially in the form filed as Exhibit 4.1 (the "Indenture") to the 462(b)
Registration Statement. The 462(b) Registration Statement covering the offer and
sale of the Additional Notes is being filed with the Securities and Exchange

assumed the genuiness of all signatures, the authenticity of all documents
submitted to us as originals and the conformity to all authentic original
documents of all documents submitted to us as copies. Based on the foregoing, it
is our opinion that:
     Each Guaranty issued by each respective Guarantor has been duly authorized
by the respective Guarantor and when executed, authenticated, and delivered in
accordance with the terms of the Indenture and when the Addtional Notes are paid
for in the manner and at the price set forth in the 462(b) Registration
Statement, will constitute the legal, valid and binding obligation of each
Guarantor in accordance with its terms, subject to applicable bankruptcy,
insolvency, fraudulent conveyance, moratorium, reorganization or other similar
laws affecting creditor's rights or debtor's obligations and to general
principles of equity.

     The opinion expressed herein is rendered solely for your benefit in
connection with the transaction contemplated hereby. The opinion expressed
herein may not be used or relied on by any other person, nor may this letter or
any copies hereof be furnished to a third party, filed with a governmental
agency, quoted, cited or otherwise referred to without our prior written
consent, except as provided below.

     We hereby consent to the filing of this opinion as Exhibit 5 to the 462(b)
Registration Statement and to the use of our name in the prospectus contained
therein, under the caption "Legal Matters" in the prospectus forming a part of
the 462(b) Registration Statement. In giving such consent we do not thereby
admit that we are in the category of persons whose consent is required under
Section 7 of the Securities Act.


                                        Sincerely yours,
