Sporthfish flywheel puller kit for Mercury/Mariner/Force/Yamaha 45HP+ — 4-piece set, 1-1/2-in & 5/8-in threads

This compact four-piece kit combines a threaded puller, crankshaft protector and a heavy-duty lifting ring to make servicing and moving outboard engines safer and more efficient. Built to match common OEM thread sizes used on many older and modern 45HP+ outboards, the set helps technicians and DIY boat owners remove flywheels to access stators, triggers and other internal components, then lift or reposition the engine when needed.

Which engines and years will this puller and lift ring work with?

The Sporthfish set was made to fit a wide range of Mercury, Mariner, Force and Yamaha outboards, spanning historic models from the 1960s through recent designs. It targets 45HP and larger engines where the specified thread sizes are used on the crankshaft and bolt fittings.

• Compatible brands: Mercury, Mariner, Force, Yamaha
• Commonly used on 45HP and larger outboards
• Covers many models from the 1960s to present
• Always verify thread dimensions before use

What thread sizes and fitment details should I check?

Thread compatibility is critical for safe, damage-free removal. The puller uses a 1 1/2"-16 TPI threaded shaft to match crankshaft threads, while the lifting ring and bolt use a 5/8"-18 TPI thread that pairs with the puller assembly. Confirm these dimensions on your engine before proceeding.

• Puller: 1 1/2"-16 TPI — matches crankshaft thread
• Lifting ring/bolt: 5/8"-18 TPI — mates with the puller bolt
• OEM-style threading for direct screw-in fit
• Measure your crankshaft thread if unsure

How do I use the puller and lift ring safely?

Start by lubricating threads to prevent galling, then thread the puller into the crankshaft until it seats against the flywheel. Attach the lifting ring if you need to move the motor, and tighten the central bolt to draw the flywheel free. Use steady, incremental pressure and keep hands clear as parts separate.

• Apply lubricant to both puller and crank threads first
• Screw puller fully into crankshaft before tightening the center bolt
• Use the lifting ring for engine removal from the transom
• Progress slowly and inspect threads periodically

What advantages does this Sporthfish set offer over improvised methods?

The kit provides OEM-size threads and a crankshaft protector to avoid damage that can occur with generic or jury-rigged tools. Its matched threads and lifting eye reduce the risk of stripped threads or bent flywheels while making the process faster and more repeatable for routine service tasks.

• Precision threading reduces cross-threading risk
• Crankshaft protector prevents marring or deformation
• Lift ring doubles as a safe engine handling point
• Saves time compared with makeshift pullers or hammers

Who is this kit for? The Sporthfish flywheel puller and lift ring set is aimed at marine mechanics, boat owners who perform their own maintenance, and restoration shops working on older outboards. If you regularly remove flywheels to replace stators, do timing work or need a secure lifting point for 45HP+ Mercury, Mariner, Force or Yamaha engines, this set gives the correct thread sizes and protection to do the job properly. Always confirm your engine's thread specifications before purchase and follow safe lifting and torque practices when using the tools.
