Maintain smooth driveline operation with this New EMP Prop Shaft Bearing designed for OMC Cobra and King Cobra sterndrives. Manufactured to meet or exceed OEM specifications, this precision bearing supports upper U-joint shaft assemblies, helping ensure proper alignment and reduced friction under load.
Bearings within the upper drive assembly are subjected to high RPM, torque loads, and constant exposure to marine conditions. Worn bearings can cause vibration, noise, and premature wear to surrounding components. Replacing a failing bearing during service helps protect gears and shafts while restoring dependable performance.
This bearing replaces OEM part number 983878 and fits select 1986–1993 Cobra and King Cobra sterndrive models.
