🔧 Product Description

Genuine Honda BF250D Flywheel Assembly - Part Number: 31110-ZVL-B10

A genuine used Honda flywheel for selected later-generation BF250D four-stroke outboards.

The flywheel mounts to the crankshaft above the oil-pump and charging-coil assembly. Its internal magnets generate electrical power through the stator, while the outer structure carries timing references used by the engine-management system. Honda BF250D parts diagrams list 31110-ZVL-B10 alongside flywheel boss 31116-ZY3-020.

• Low or absent charging output

• Irregular crankshaft-position signal

• Engine misfires or will not start

• Damaged crankshaft taper or keyway

• Flywheel contacts the stator

• Cracks around the centre hub
