Fitment
This engine mounting bolt kit is designed to fit most Mercury outboard engines using a standard four-bolt transom mounting arrangement.
The included mounting bolts measure 5.5 inches long. Verify that this bolt length is appropriate for your engine bracket, transom thickness and installation before ordering.
Although this kit fits most Mercury outboard applications, mounting requirements can vary depending on the engine, transom thickness, jack plate, setback bracket or other installation hardware.
Measure and verify the required 5.5-inch bolt length before installation.
What This Part is Used For
Outboard engine mounting bolts pass through the engine's transom brackets and the boat transom to securely attach the outboard to the boat.
The four included bolts provide the primary mechanical connection between the engine and transom. Washers help distribute the clamping load, while the included Nylock nuts help resist loosening during normal boat and engine operation.
When to Replace Outboard Mounting Hardware
Engine mounting hardware should be inspected whenever an outboard is removed, installed, repositioned or serviced at the transom.
Replacement should be considered if the existing mounting hardware shows corrosion, damaged threads, deformation or other signs of deterioration.
Installation Notes
- Verify the 5.5-inch bolt length before installation.
- Inspect the boat transom before mounting the engine.
- Use all required washers and mounting hardware.
- Follow Mercury's recommended mounting locations and installation procedure.
- Follow the appropriate torque specifications for the engine installation.
- Use an appropriate marine sealant around transom penetrations as required by the boat or engine manufacturer's installation procedure.
- Recheck mounting hardware after installation as recommended by the manufacturer.
