Perfect Compatibility for Your Setup

This puller shines on a wide range of sterndrives and outboards, including those from leading brands with gimbal-mounted powerheads. It's tailored for 1.5- to 3-inch bearings commonly found in mid-range to high-horsepower setups. Double-check your model's service manual for exact sizing, but its adjustable design covers most applications from the 1980s through modern builds.

Owners of single or twin-engine rigs report flawless performance, whether pulling rusted factory bearings or upgrading to ceramic-coated aftermarket ones for better longevity.

Extend the Life of Your Engine with Smart Maintenance

Beyond just pulling bearings, regular gimbal service prevents water intrusion that leads to premature failures. Pair this tool with annual inspections: check bellows for cracks, repack U-joints, and monitor for play in the pivot points. Using the right puller reduces housing damage by up to 70% compared to makeshift methods like screwdrivers or torches, keeping your boat trailering-ready year-round.
