3mirrors Flywheel Puller Kit for Mercury Mariner Outboards 1 1/2"-16 Thread — Lift Ring & Crank Protector

This precision puller set includes a protective crankshaft cap, a threaded pusher bolt, and a lifting ring engineered to replace common Mercury/Quicksilver part numbers. Built for hobbyists and marine technicians, the kit fits many four- and six-cylinder outboards across 45HP and larger models and offers a cost-effective way to service engines without specialized marina equipment.

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

The kit is made for engines that accept a 1 1/2"-16 threaded flywheel puller and covers a wide range of Mercury and Mariner models from mid- to high-horsepower outboards. It also works with some Force and Yamaha units that share the same thread pitch and diameter. Always verify the thread type on your flywheel before purchase.

• Compatible with many 45HP and up Mercury/Mariner models (4-cyl and V6 ranges).
• Replaces Mercury/Quicksilver part numbers 91-849154T1, 91-73687A1 and 91-73687A2.
• Fits units using 1 1/2"-16 flywheel threads—measure thread diameter to confirm.

How do I use the puller safely and effectively?

Thread the lifting ring into the flywheel and install the protective cap over the crank nose to prevent damage. Turn the pusher bolt evenly to apply steady pressure until the flywheel comes free; applying a light lubricating oil can reduce friction and ease removal. Work on a stable surface and follow basic safety practices when handling engine components.

• Install crankshaft protector first to shield the crank snout.
• Apply light lube to threads and flywheel contact points for smoother operation.
• Turn the precision pusher bolt slowly and check alignment regularly.

What’s included and what materials and sizes should I expect?

The kit contains a threaded lifting ring, a push bolt with fine 5/8-18 threading in the pusher portion, and a crankshaft protector sized to match common Mercury configurations. Components are manufactured for durability and repeated shop use, designed to handle stresses encountered during flywheel extraction. Check the thread diameter and pitch to ensure a correct match with your engine.

• Lift ring compatible with 1 1/2"-16 flywheel threads.
• Pusher bolt with 5/8-18 precision threads for controlled pressure.
• Protective crankshaft cap to prevent nicks or gouges on the crank nose.

Can this puller replace a marina visit and is it cost-effective?

For routine flywheel removal and basic outboard servicing, this puller kit provides a practical alternative to paying labor rates at a marina. While complex engine repairs or diagnostics may still require professional attention, having the right puller saves time and money for removal and reinstall tasks. The kit is a good investment for boat owners who do their own maintenance.

• Helps DIYers remove flywheels without expensive shop fees.
• Durable construction intended for repeated use over seasons.
• Compact kit that fits in a standard tools bag for on-boat jobs.

Who is this for: The 3mirrors Flywheel Puller Removal Tool kit is aimed at boat owners, marine hobbyists, and small-shop mechanics who service Mercury, Mariner, Force or compatible Yamaha outboards that use a 1 1/2"-16 flywheel thread. If you perform regular maintenance, rebuild stators, or remove flywheels for inspection, this kit provides a precise, protective, and affordable way to do the job yourself. If you're unsure about fitment, measure your flywheel thread diameter and pitch or contact us before purchase for guidance.
