Mercury MerCruiser Quicksilver Zeus Trim Cylinder Screw M8 x 110 8M0041797
Mercury MerCruiser Quicksilver 8M0041797 is a genuine OEM M8 x 110 mm screw used in the trim-component assembly of compatible Mercury MerCruiser Zeus pod-drive systems. Zeus parts diagrams place this service fastener at the trim-cylinder and hydraulic-manifold assembly. It replaces earlier Mercury screw 8M0027376.
Compatible Applications

- MerCruiser Zeus 3000, serial 0M968893 through 0M968955
- MerCruiser Zeus 3000, serial 0M969003 and up
Serial-number fitment: Zeus pod-drive components changed across production ranges. Confirm the drive serial number and trim-component diagram before ordering. The M8 x 110 specification alone does not establish interchangeability with another fastener.

When to Replace This Screw
Replace the screw when the applicable service procedure calls for replacement after removal, or if its threads are stretched, damaged, or corroded. Replacement is also appropriate when the head or drive surface is damaged, severe corrosion is present, or the original fastener is missing or of uncertain specification.
Installation Notes
Applicable Mercury Zeus service documentation specifies tightening 8M0041797 to 30 ft-lb / approximately 40.7 N·m with Loctite 271. Follow the current service procedure for the exact drive serial number before installation.
Because this fastener is part of a hydraulic trim assembly, inspect the cylinder mounting points, manifold, O-rings, pins, sensors, and surrounding hardware whenever the assembly is apart.
Technical FAQ
Can a generic M8 x 110 screw be substituted?
No substitution should be made based only on thread diameter and length. Match the exact Mercury part number and the serial-specific diagram.
What earlier part number does it replace?
8M0041797 supersedes Mercury part number 8M0027376.
Is this used throughout every Zeus drive?
No. Verify the drive serial number and trim-component diagram because hardware can differ by production range and assembly position.
Parts Desk Insights
Best use case: Replacing the specified trim-cylinder or manifold mounting fastener during service on a compatible Zeus 3000 pod drive.
Most common mistake: Treating it as an ordinary M8 bolt and overlooking its diagram position, 110 mm length, tightening specification, and locking-compound requirement.
Fitment guidance: Match part number 8M0041797 to the exact drive serial number and trim-component diagram. Confirm the required quantity because Mercury diagrams may use more than one screw at this mounting location.
