Federal Marine Motors
Saint Petersburg manufacturer of Federal Flexible Couplings for marine and industrial engines since the 1950s.
About
Federal Marine Motors has been making Federal Flexible Couplings in Saint Petersburg for over 65 years. These couplings connect engine shafts while absorbing vibration and reducing noise. They handle misalignment between shafts, prevent metal-to-metal contact that causes rumble, and protect transmission bearings and seals from wear. The couplings need no lubrication or maintenance and install without shortening shafts or changing their position. Neoprene rubber components transmit power while allowing engines on rubber mounts to move freely, and can be replaced if damaged. Located on 47th Avenue North in Saint Petersburg, Federal Marine Motors serves boat builders, engine manufacturers, and marine service shops across the region.
