Thank you, Tom. Please turn to Slide 16, and I'll begin our segment review with the Food Service Equipment Group. Sales decreased 9% from Q4 last year, driven primarily by the continued softness in refrigeration demand as well as ongoing actions to eliminate less profitable products. We continue to make significant progress operationally as gross margin increased to 250 basis points and operating margin was 11.4%.
Refrigeration sales decreased about 20% in the quarter as the result of continued soft sales to large national chains, dollar stores and drug retail stores. Strong sales through dealers partially offset the overall revenue decline. On the positive side, we are beginning to see some of the large national chains ramp up their investment plans for projects set to commence in 2017.
In light of customers' reduced spending, we are aggressively driving lean in our Refrigeration plants and managing its cost structure. I have to commend the Refrigeration management team for giving their best efforts to protect the business's profitability during the sales downturn.
In Cooking Solutions, revenue increased mid-single-digits year-over-year, primarily driven by sales through dealers. We saw a good growth from Ultrafryer in traditional cooking equipment and slower growth in grocery store retail. This was partially offset by actions to eliminate lower-margin commodity products. What is particularly noteworthy is the 500 basis point year-over-year increase in cooking operating margins despite about $1 million in lost sales from the product rationalization strategy. The margin improvement was aided by improved operating performance, stabilization in our plants and select price increases on lower-margin products.
Specialty Solutions was up in Q4, driven by our espresso pumps business, partially offset by exchange rate declines. We're particularly excited by new pumps products that will provide our customers with opportunities to offer innovative carbonated beverages, enhance CO2 safety and lower maintenance costs. Display merchandising is showing good momentum as orders increased high single digits. We are making significant progress in Food Service as we apply Standex's operational excellence initiative to all of our production facilities. With these initiatives in place and demonstrating early results, the team is adding focus to its commercial strategic initiatives focusing on a [ph] power point, attractive adjacencies and sales force effectiveness.
Please turn to Slide 17. Looking ahead, we anticipate 2 more quarters of headwinds in Refrigeration. We believe we are at the bottom of the trough in small footprint retail, and the large chain rate of decline has slowed. We do expect some improvement in 2017 as a number of our customers will begin to invest in new rollouts. I'm also encouraged by top line growth laneways and new business opportunities in each of the cooking and Food Service businesses.
Turn to Slide 18. The Engraving Group had another good quarter, with sales increasing 3.2% over Q4 of last year, with double-digit organic growth in orders in backlog. Sales were driven by auto mold texturizing in Asia and Europe.
In North America, Q4 was shifted to -- some work was shifted from Q4 to Q1 due to customer requests. Operating income was up 23.6%. We're encouraged with the progress of our design hubs as we changed the game with our sales approach through these centers of excellence. We've opened our newly renovated Architexture design studio in Detroit in the second quarter of fiscal '17, and we will be hosting an Investor Day at that location on Wednesday, September 21. During the quarter, we sold our Roll, Plate and Machinery business to enable us to devote full focus and resources on higher growth and better-return businesses.
As you'll recall, last quarter, we mentioned that our Engraving segment margins were down because of startup costs associated with nickel shell, laser and other applications. Nickel shell tanks are now at capacity and our laser machine has also been productive in delivering results. We anticipate that the momentum in Engraving will continue in the new fiscal year as we focus on meeting automotive Mold-Tech demand. We expect moderate growth in fiscal 2017 in Europe, Asia and North America.
Near term, automotive customer schedules are indicating flat to slightly down Q1. With the divestiture of Roll, Plate and Machinery, the management team is now devoting their energies to exploring growth opportunities with market tests.
Please turn to Slide 19, our Engineering Technologies Group. Sales were down 8.7% year-over-year, primarily due to lower demand in the oil and gas markets, contract timing in the space industry and lower medical and general industrial markets. This was partially offset by 14% growth in aviation sales. Our ramp-up in aviation continues, and we're creating the capacity to fulfill customer needs. Our new Aluminum Center of Excellence in Wisconsin is now up and operational . The longer-term aviation awards are beginning to ramp, and operational improvement initiatives are benefiting the bottom line as evidenced by a 16% operating income during the quarter.
Looking ahead, we are continuing to reposition the business to capitalize on aviation demand and expand capacity to support existing contracts. This includes the ramp-up of the new Wisconsin plant. The first half of 2017 year-on-year sales comparison will continue to be impacted by the oil and gas and medical sales.
Slide 20 clarifies the movement of sales to different end markets. For the quarter, oil and gas sales declined 8.9%, while aviation sales grew 4.9%. In the full year, oil and gas declined 18.3%, and aviation grew 9%. As we described last quarter, our sales in the oil and gas end markets have hit bottom. For 2017, the continued ramp of aviation sales will provide net growth for the business.
Please turn to Slide 21, Electronics. Electronics sales increased 11% due to the Q2 2016 acquisition of Northlake as well as program launches in Europe, partially offset by softness in China. Orders in backlog were up, due to growth in industrial, automotive and security markets and the contribution from Northlake. We won some attractive new applications in the North American market that will begin to drive growth in fiscal '17. Operating margin was strong at 18% due to cost-savings activities for manufacturing moves in China and Mexico and improving efficiencies.
Sensors were up modestly from the prior year, and we're accelerating growth laneways in sensor technologies through market tests. We've seen new business opportunities for sensor technologies in industrial, automotive and security markets, and for magnetics, in power distribution, electric vehicles and medical devices. We expect our new sensor programs to continue to drive growth over the next 12 months.
Our Hydraulics Group, as you can see on Slide 22, had a very strong quarter. Sales were up 15.3% year-over-year, primarily due to the continued strengthening in our traditional North American dump truck and trailer markets, which are tied to the North American construction environment. Operating margin was 19.8%. We continue to capture new OEM platforms in the refuse space through product line expansion and sales efforts. Looking forward, we're seeking new business outside of our traditional markets and the refuse space. We're making progress in the airline support equipment space and look forward to capitalizing on additional growth opportunities in other markets. We also are expanding production in China to meet increased demand and utilizing our operational excellence toolkit throughout the business and leveraging the recent capital investments in technology.
Please turn to Slide 23. In summary, we had a very solid finish to the quarter and to the year. And we're well positioned in our markets as we enter fiscal 2017. In the fourth quarter, we grew sales by double digits in 3 of our 5 businesses and reported at least 15% EBIT margin in 4 of the 5 businesses. In fiscal 2017, we are focused on sales and margin expansion in all of our businesses, addressing top line growth challenges in Food Service Equipment and capitalizing on aviation opportunities in Engineering Technologies.
As we look to the future, our balance sheet is well positioned to fund growth, CapEx and acquisitions as we continue to deploy the Standex Value Creation System. We have an active and healthy acquisition pipeline with companies that support our business's strategies and meet our value creation criteria. Finally, we would like to invite you to our third Investor Day to be held in our Architexture Design Center in Detroit on Wednesday, September 1. Please contact our Investor Relations for more information.
With that, we would be pleased to take your questions. Operator?
