47608A1 Mercruiser Drive Plate | Genuine Used Part

🔧 Product Description

Genuine Used Mercury MerCruiser Flywheel Drive and Damper Plate Assembly - Part Number: 47608A1

A genuine pre-owned Mercury MerCruiser flywheel-mounted drive plate for selected GM-based V8 inboard and sterndrive marine engines.

The assembly bolts to the engine flywheel and transfers crankshaft torque to the transmission or drive input shaft. Its sprung or flexible centre helps absorb torsional vibration and driveline shock.

Mercury identifies 47608A1 as a flywheel drive-plate assembly.

🔌 Function

The drive plate transfers engine torque while allowing limited movement in its flexible or spring-loaded centre.

Common signs of failure:

• Rattle at idle

• Clunk when selecting gear

• Engine runs but the propeller does not turn

• Centre spline strips

• Springs become loose or break

• Plate cracks around the flywheel bolts

• Excessive torsional vibration

• Transmission input shaft has red dust or spline wear

• Metallic noise between the engine and transmission

Recommended checks before installation:

• Count and measure the centre splines

• Compare bolt-hole spacing and plate offset

• Inspect all springs or flexible elements

• Check for cracks around mounting holes

• Inspect the flywheel face

• Check transmission input-shaft alignment

• Replace damaged mounting bolts

• Torque fasteners evenly to the correct specification

• Confirm engine-to-transmission alignment after installation

📦 Condition

• Genuine Mercury MerCruiser used part

• Pre-owned driveline component

• Surface corrosion, marks and spline wear may be present

• Inspect the centre, springs and mounting holes before installation

• Supplied components are limited to those shown or described

• Supplied in protective or equivalent packaging
