Silversides became a part of the Combined Great Lakes Navy Association in Chicago, Illinois, behind Chicago's Naval Armory on 24 May 1973.
For years, the submarine was tended by a small crew of dedicated volunteers, drawn to her illustrious history and technical marvels.
They donated tens of thousands of man-hours to restore her, maintained her at their own expense, and served as docents and chaperones.
When association volunteers first stepped on board, they faced a musty, mildewed sub with paint peeling off in sheets inside and out, and junk scattered everywhere.
After many years, the refrigeration compartment had produced a growth so thick, they could be measured in multiple inches instead of millimeters.
Evidence of water damage prevailed in the forward compartments but the aft end was in reasonably good condition.
Topside, the decking was weathered and worn in spots and some areas of the superstructure were rusted and in need of replacement.

Volunteers quickly took steps to stop the decay.
Rotted lines were replaced and the boat re-secured to the pier, the bilges were pumped dry, electric power and heat were brought on board and a leak in the No.
3 torpedo tube sealed off.
The first major renovation completed was stripping, undercoating and repainting the hull to the water line.
The job took several months, with a break over the winter, but once completed, the Silversides looked nearly new.
Below decks, the boat was cleaned and general restoration got under way.
Considerable rewiring was done to bring light to all areas of the boat, the plumbing underwent investigation for leaks sprung in once-frozen pipes and a crew set about surveying the Fairbanks Morse 38D8 ​¹⁄₈ nine-cylinder, 1,535 hp (1,145 kW), opposed-piston engines.
The seven-cylinder auxiliary engine was brought back to life in 1975.

She was moved to Navy Pier in 1979.
That July, the first main engine, No.
3, was brought back to life for the first time since 1946.
The No.
4 engine was restored in time for the 1984 US Submarine Veterans of World War II convention.
In 1987, the submarine was moved to Muskegon, Michigan, to serve as the centerpiece of the new Great Lakes Naval Memorial & Museum.

Normally, United States Navy submarines are dry-docked every five years while on active duty.
If permanently moored in fresh water the maintenance interval can be extended to 25 years.
In 2004, 55 years after Silversides's last dry-docking, the museum and two submarine veterans organizations formed a "Save the Silversides" fund and began soliciting tax-deductible donations through veterans groups and military publications.
 They based their plans on the dry-dock overhaul of USS Cobia (SS-245), a memorial in Manitowoc, Wisconsin, which cost US$500,000 in 1996.
