The Flywheel Puller and Powerhead Lifting Tool Kit from Buckshot Racing #77 is a professional service tool built for two jobs every serious outboard mechanic faces: removing a flywheel safely and lifting a powerhead securely. It is designed as a direct replacement for the Mercury / Quicksilver Flywheel Puller 91-849154T1 and the Mercury Lift Ring 91-90455-1, also commonly listed as 90455T1.
This kit fits outboards with a 1-1/2"-16 threaded flywheel center hole, a common thread size used across many Mercury, Mariner, Yamaha, and Force engines. That includes a wide range of 2-stroke, OptiMax, and 4-stroke outboards, from mid-range fishing motors to larger V6 performance platforms.
What this tool kit does
This kit combines a threaded flywheel puller and a powerhead lifting eye in one package. The puller removes the flywheel from the crankshaft taper without prying, hammering, or risking damage to the flywheel, crankshaft, or ignition components. The lifting eye threads into the same flywheel center hole so you can remove or reinstall the powerhead with a hoist or crane using the correct lifting point.
For shop work, rebuilds, and race-motor service, that means cleaner disassembly, safer lifting, and less chance of damaging expensive engine parts.
What’s included
Each kit includes a black oxide threaded flywheel puller body, a Grade 8 pusher bolt, a crankshaft protection slug, and a lifting ring / lifting eye. The black oxide finish helps resist wear and corrosion in marine environments, while the fine-thread pusher bolt gives you smooth, controlled pulling force. The protection slug is an important detail because it helps keep the pusher bolt from damaging the crankshaft end during flywheel removal.
Fitment and common model families
The key fitment detail is simple: if your outboard flywheel has a 1-1/2"-16 center thread, this is the correct tool style.
On the Mercury side, that commonly includes many 2-stroke Mercury and Mariner outboards in the 45 HP to 300 HP range, along with popular V6 families such as 2.0L, 2.4L, 2.5L, 3.0L, and 3.2L models. In real-world service terms, that often means engines and model groups such as XR4, XR6, Pro Max, 225 Pro Max, 260 EFI, 280 ROS, 225X, 300 Drag, 300X, 300XS, and other Mercury Racing V6 applications, as well as many standard fishing outboards.
It is also commonly relevant to Mercury OptiMax / DFI platforms such as 135 OptiMax, 150 OptiMax, 175 OptiMax, 200 OptiMax, 225 OptiMax, 250XS, and 300XS, plus many Mercury 4-stroke models that use the same flywheel center thread arrangement.
Yamaha and Force outboards in the same general 45 HP to 300 HP range are also common applications where this puller style is used.
Because thread size is what matters most, the safest way to confirm fitment is to verify that your flywheel center hole is 1-1/2"-16 before ordering.
How to use the flywheel puller
Secure the engine on a stand, transom, or fixture so it cannot move during service. Remove anything attached to the flywheel that would interfere with safe access. Thread the puller body fully into the flywheel center hole and make sure it seats squarely.
Place the crankshaft protection slug in position, then thread in the Grade 8 pusher bolt. Apply steady, even torque to the pusher bolt until the flywheel begins to release from the taper. If the flywheel is stubborn, apply penetrating oil around the hub and continue with controlled pressure. Once it breaks free, remove the flywheel carefully and place it on a clean surface.
How to use the lifting eye
After the flywheel is removed, thread the lifting ring / eye into the same 1-1/2"-16 center hole. Make sure it is fully seated before attaching a hoist or crane. Confirm that all powerhead mounting bolts, hoses, wiring, and linkages have been removed or disconnected as required before lifting.
Raise the powerhead slowly, keep the load balanced, and avoid sudden movement. For installation, reverse the process and follow the proper service procedure for your specific engine.
Why this kit is better than improvised methods
Using the wrong puller can damage the flywheel, crankshaft, or stator area. Using the wrong lifting point can damage the engine or create a serious safety problem in the shop. This kit eliminates guesswork by giving you the correct threaded engagement, controlled puller force, and a secure lifting point in one package.
That makes it a smarter solution for 2-stroke, OptiMax, and 4-stroke outboard service, whether you are working on a fishing motor, a tournament rig, or a high-performance Mercury V6.

Final takeaway
The Buckshot Racing #77 Flywheel Puller and Powerhead Lifting Tool Kit is a durable, professional-grade replacement for Mercury 91-849154T1 and 91-90455-1 / 90455T1. If your engine uses a 1-1/2"-16 flywheel center thread, this kit gives you a safe, controlled way to remove the flywheel and lift the powerhead on many Mercury, Mariner, Yamaha, and Force 2-stroke, OptiMax, and 4-stroke outboards.
