Accounting Policies [Abstract]
Effect of Covid-19 Pandemic, Policy [Policy Text Block]	Recent events In March 2020, the World Health Organization (“WHO”) declared that a new strain of coronavirus that originated in Wuhan, China, and has rapidly spread around the world (“COVID- 19 outbreak’) is a pandemic that poses significant risk to the international community. This outbreak has contributed to shelter-in-place policies, unexpected factory closures, supply chain disruptions, and market volatility causing substantial declines in market capitalization, and occurring in the midst of an already challenging economic environment in some of our markets, most notably the oil and gas market. This market has been experiencing an unprecedented drop in prices, steeper than it historically has been, primarily driven by an oversupply occurring around the world, from both the Organization of Petroleum Exporting (“OPEC”) and non-OPEC countries. The occurrence of the COVID- 19 outbreak drastically impacts the demand side of that market, as economic contractions and social distancing restrictions will likely curtail consumer behaviors, and further exacerbating its dismal prospects. As a result of the COVID- 19 outbreak, the Company’s operations have decreased, starting on or around mid- March 2020, on a staggered basis, to curtail the spread of the virus and in compliance with regulatory authorities. The Company’s plants and offices around the world have been subject to intermittent shutdowns, impacting the timeliness of supply chain arrangements and product shipments. The operational impacts of decreased Company activity, such as the inability to ship products on time due to supply chain disruptions, occurred during a one to two week period out of the fiscal quarter that consisted of thirteen weeks, and are included in these financial results. Aside from operational impacts and its results on our operations during the quarter, the occurrence of the COVID- 19 outbreak also necessitated a rigorous assessment of the Company’s entire balance sheet. As described further in Note I, Goodwill and Other Intangibles, the Company recorded significant non-cash impairment charges during the quarter. While the Company continues to have a positive outlook of its operations in Europe, both in the European Propulsion and European Industrial reporting units, and remains committed to supporting those operations, the adverse economic effects of the COVID- 19 outbreak are not fully known. However, there is consensus that the impact will be adverse. Hence, management has modeled those expectations from industry and subject matter experts and determined that prudence in the face of uncertainty warrants a robust scenario modeling approach. This approach was deployed in the Company’s goodwill and long-lived asset impairment analyses. In assessing the current environment, management expects that a contraction of the global economy, as is predicted by many experts, would reduce or shift the demand for its products in the near term. For example, the Company expects that the demand for certain of the reporting units’ end-market products, such as passenger leisure cruise vessels, passenger ferries, and other commercial vessels that operate based on general economic activities, will likely be adversely impacted as social restrictions are put in place by governments to curb the outbreak. As a consequence of these macroeconomic developments, market insights and expectations, the Company has recorded asset impairment charges in the quarter, primarily consisting of goodwill and other intangibles, in the amount of $27,603. The full impact of the COVID- 19 outbreak continues to evolve as of the date of this report. The depth and duration of the pandemic is unknown. Management is actively monitoring the global situation and its effect on its financial condition, liquidity, operations, suppliers, industry, and workforce. This is discussed further in Item 2, Management’s Discussion and Analysis, of this report.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards In June 2018, the Financial Accounting Standards Board (the "FASB") issued guidance (ASU 2018 - 07 ) intended to simplify the accounting for share based payments granted to nonemployees. Under the amendments in this guidance, payments to nonemployees would be aligned with the requirements for share-based payments granted to employees.

The amendments in this update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The amendments in this guidance are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 ( the Company’s fiscal 2021 ), with early adoption permitted. The Company is currently evaluating the potential impact of this guidance on the Company’s disclosures.

In March 2020, the FASB issued guidance (ASU 2020 - 04 ), intended to provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The amendments in this guidance are effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the potential impact of this guidance on the Company’s financial statements and disclosures. Special Note Regarding Smaller Reporting Company Status Under SEC Release 33 - 10513; 34 - 83550, Amendments to Smaller Reporting Company Definition, the Company qualifies as a smaller reporting comp any and accordingly, it has scaled some of its disclosures of financial and non-financial information in this quarterly report. The Company will continue to determine whether to provide additional scaled disclosures of financial or non-financial information in future quarterly reports, annual reports and/or proxy statements if it remains a smaller reporting company under SEC rules.
