Troubleshooting & FAQ
What is this tool specifically used for?
This is a professional-grade slide hammer puller designed to extract gimbal bearings and bearing races from various sterndrives and outboard lower units, primarily for MerCruiser Alpha/Bravo drives and Mercury outboards.
How can I confirm this tool will fit my engine?
It is designed for a broad range of MerCruiser drives and outboards from Mercury, Yamaha, Suzuki, and Johnson/Evinrude. Please review the detailed "Engine & Model Compatibility" table on this page to verify your specific model and year.
Is this a genuine Mercury tool?
No, this is an aftermarket tool built to the same specifications as Mercury OEM part 91-34569A1. It offers comparable performance and durability at a better value.
The puller jaw doesn't fit behind the bearing race. What's wrong?
This is a common situation with some applications. As noted in the specifications, you may need to perform a minor modification by grinding a small amount of material from the bottom of the puller jaws to allow it to slip behind certain races.
When should I use the 2-jaw versus the 3-jaw adapter?
The 3-jaw puller provides a stable, evenly distributed pulling force and is ideal for most gimbal bearings. The 2-jaw adapter is intended for situations with limited clearance or for gripping bearing races where a 3-jaw puller will not fit.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
