Federal Marine Flexible Shaft Coupling Coupler

Federal Marine Flexible Coupling for 1.75" shaft. Purchased for trawler but never installed, boat is gone but parts are still here.
Measures 5.875" across, 3.75" front to back.

$150 includes Priority mail shipping within continental US.

Federal flexible boat shaft couplings offer all the advantages of Drivesavers, plus enhanced versatility thanks to specially engineered, flexible trunnions. Advantaged include:
Protect transmission thrust bearings and seals from stress and wear due to shaft misalignment including parallel and angular misalignment.
No metal to metal contact; prevents shaft rumble from reaching engine.
No lubrication or maintenance required.
Easily installed; no shaft shortening or change of shaft location.
Neoprene Rubber trunnions transmit thrust and torsional loads.
Trunnions can easily and economically be replaced in case of damage.
Dampen oscillating shaft vibration in diesel installations.
Allows engines on rubber mounts to float free.
Engines on rubber mounts move ahead and jackknife under thrust of propeller shaft; FEDERAL flexible couplings absorb this and reduce vibration at high speeds.
Allow Engine alignment without special tools.
