Sporthfish Flywheel Puller Kit for Outboards — 4‑Piece 1.5"-16 Puller & 5/8"-18 Lift Ring, Fits Mercury/Mariner/Force/Yamaha 45HP+

Sporthfish 91-849154T1 flywheel puller and 91-90455-1 lift ring set is a 4-piece outboard service kit that removes flywheels and provides a secure lifting eye for Mercury, Mariner, Force and Yamaha 45HP+ engines.

This precision-engineered tool set combines a threaded flywheel puller with a crankshaft protector and a matching lifting eye ring to make stator and trigger access, removal and engine lifting quicker and safer. Built to match common OEM thread sizes used on many outboards from the 1960s to modern models, the Sporthfish kit is intended to reduce manual effort and protect the crankshaft during maintenance.

How does this kit remove a stuck outboard flywheel?

The 91-849154T1 puller threads onto the crankshaft and applies even axial force to separate the flywheel without hammering or prying. The included crankshaft protector prevents thread damage and preserves the crank’s journal as pressure is applied.

• 1 1/2"-16 TPI main puller thread for direct crankshaft match
• Crankshaft protector to prevent surface marring
• Evenly distributed pulling force reduces risk of breaking fins
• Lubricate threads before use for smooth operation

Will this fit my Mercury, Mariner, Force or Yamaha outboard?

Sporthfish designed the set to match the common OEM thread standards on many 45HP and larger outboards, spanning models made from the 1960s to current production. Always verify your engine’s thread pitch and size before ordering to ensure compatibility.

• Main puller uses a 1 1/2"-16 TPI thread — confirm your crankshaft thread
• Lift ring and puller bolt feature 5/8"-18 TPI thread for accessory fit
• Compatible with many Mercury, Mariner, Force, Yamaha outboards 45HP+
• Works for flywheel removal prior to stator or trigger service

How does the lift ring make handling engines easier?

The 91-90455-1 lifting eye provides a secure attachment point for lifting slings or hoists when removing or moving the motor from a transom or workbench. Using the correct threaded eye reduces the chance of slippage and helps keep the engine balanced during lifts.

• Threaded 5/8"-18 TPI lifting eye for secure hoist connection
• Reduces need for improvised lifting points that can damage the motor
• Useful when transom removal or repositioning of heavy outboards
• Pairs with the puller for safe flywheel removal workflow

What precautions and best practices should I follow?

Using the right thread, proper lubrication and controlled force will protect both the tool and your engine. Avoid over-torquing; inspect threads and the crankshaft protector before each use to maintain safe operation.

• Lubricate puller threads and crankshaft mating surfaces first
• Confirm thread pitch (1 1/2"-16 TPI and 5/8"-18 TPI where applicable)
• Apply even, incremental force when extracting the flywheel
• Check the crankshaft protector for wear; replace if damaged

Who is this for: Boat owners, DIY marine mechanics and professional technicians who service 45HP and larger outboard engines and need a reliable flywheel removal tool and lifting eye. This Sporthfish 4-piece set suits anyone working on stator or trigger replacement, or who must lift and reposition outboards safely, provided they confirm matching thread sizes first.
