             Report of Independent Registered Public Accounting Firm

Plan Administrator
The Gorman - Rupp Company 401(k) Plan

We have audited the accompanying statements of net assets available for benefits
of The Gorman-Rupp Company 401(k) Plan as of December 31, 2003 and 2002, and the
related statement of changes in net assets available for benefits for the year
ended December 31, 2003. These financial statements are the responsibility of
the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2003 and 2002, and the changes in its net assets available for
benefits for the year ended December 31, 2003, in conformity with U.S. generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedules of assets
(held at end of year) as of December 31, 2003, and reportable transactions for
the year then ended, are presented for purposes of additional analysis and are
not a required part of the financial statements but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. These supplemental schedules are the responsibility of the Plan's
management. The supplemental schedules have been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

1. DESCRIPTION OF THE PLAN

The following description of The Gorman - Rupp Company 401(k) Plan (Plan)
provides only general information. Participants should refer to the Summary Plan
Description for a more complete description of the Plan's provisions.

GENERAL

The Plan is a defined contribution plan covering substantially all employees of
the Corporate, Mansfield, Industries, and Ramparts Divisions of The Gorman -
Rupp Company (Company and Plan Administrator) and Patterson Pump Company, a
subsidiary of the Company. The Plan is subject to the provisions of the Employee
Retirement Income Security Act of 1974 (ERISA).

CONTRIBUTIONS

Each year, participants may contribute up to 15% of pretax annual compensation,
as defined in the Plan. Participants may also contribute amounts representing
distributions from other qualified defined benefit or defined contribution
plans. Effective August 1, 2000, the Company contributes 40% of the first 4% of
compensation that a participant contributes to the Plan.

Upon enrollment, a participant may direct employee contributions in whole
increments to any of the investment fund options offered by the Plan. Effective
August 1, 2000, employer contributions are restricted to the Gorman-Rupp Company
Common Stock Fund. Participants may change their investment options daily.

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's contributions and
allocations of (a) the Company's contributions and (b) Plan earnings.
Allocations are based on participant earnings or account balances, as defined.
The benefit to which a participant is entitled is the benefit that can be
provided from the participant's account.

                                                                               4

                    Notes to Financial Statements (continued)

1. DESCRIPTION OF THE PLAN (CONTINUED)

VESTING

Participants are immediately vested in their contributions plus actual earnings
thereon. Participants are also fully vested in the Company contribution portion
of their accounts plus actual earnings thereon.

PARTICIPANT LOANS

Participants may borrow from their fund accounts a minimum of $1,000 up to a
maximum equal to the lesser of $50,000 or 50% of their vested account balance.
Loan terms range from 1-5 years or up to 20 years for the purchase of a primary
residence. The loans are secured by the balance in the participant's account and
bear interest at the prime rate, as quoted in the Wall Street Journal. Principal
and interest is paid ratably through payroll deductions.

PAYMENT OF BENEFITS

Upon retirement, death, or termination of employment, a participant will receive
a lump-sum amount equal to the vested value of his or her account.

PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan subject to the provisions of ERISA.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF ACCOUNTING

The financial statements have been prepared on the accrual basis of accounting.

                                                                               5

                    Notes to Financial Statements (continued)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

INVESTMENT VALUATION AND INCOME RECOGNITION

The Plan's investments are stated at fair value. The shares of registered
investment companies are valued at quoted market prices which represent the net
asset values of shares held by the Plan at year-end. The Company stock is valued
at its quoted market price as of the last business day of the Plan's year. The
participant loans are valued at their outstanding balances, which approximate
fair value.

Purchases and sales of securities are recorded on a trade-date basis. Interest
income is recorded on the accrual basis. Dividends are recorded on the
ex-dividend date.

USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates that affect
the amounts reported in the financial statements and accompanying notes. Actual
results could differ from those estimates.

3. INVESTMENTS

During 2003, the Plan's investments (including investments purchased, sold as
well as held during the year) appreciated in fair value as determined by quoted
market prices as follows:

4. NONPARTICIPANT-DIRECTED INVESTMENTS

The Gorman-Rupp Company Common Stock Fund contains participant account balances
that are both participant-directed and nonparticipant-directed. Because the fund
contains balances that are nonparticipant-directed, the entire fund is
considered nonparticipant-directed for disclosure purposes.

Information about the net assets and the significant components of changes in
net assets related to nonparticipant-directed investments is as follows:

5. ADMINISTRATIVE COSTS

Fees for legal, accounting and other services rendered to the Plan are paid by
the Company.

6. RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are
exposed to various risks such as interest rate, market and credit risks. Due to
the level of risk associated with certain investment securities, it is at least
reasonably possible that changes in the values of the investment securities will
occur in the near term and that such changes could materially affect
participants' account balances and the amounts reported in the statements of net
assets available for benefits.

                                                                               8

                    Notes to Financial Statements (continued)

7. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated May 14, 2004, stating that the Plan is qualified under section 401(a) of
the Internal Revenue Code (Code) and, therefore, the related trust is exempt
from taxation. Subsequent to this determination by the Internal Revenue Service,
the Plan was amended. Once qualified, the Plan is required to operate in
conformity with the Code to maintain its qualification. The Plan Administrator
believes the Plan is being operated in compliance with the applicable
requirements of the Code and, therefore, believes that the Plan, as amended, is
qualified and the related trust is tax exempt.

                                                                               9
