Bonbo Lower Bearing Carrier Puller for Outboard & Stern Drive - Black, Fits 115hp+ Gearcases, ACME Screw & Adjustable Arms

Bonbo Lower Bearing Carrier Puller is a heavy‑duty, adjustable tool built to remove lower unit bearing carriers from most outboard and stern drive gearcases 115hp and larger without damaging seals or housings.

This puller is engineered for marine mechanics and do‑it‑yourself boat owners who need reliable, precision extraction of stubborn bearing carriers. Constructed from high‑strength steel with an ACME threaded ball‑bearing head and adjustable swing arms, the tool adapts to a wide range of Yamaha, Johnson, Evinrude, Mercury, Honda and Mercruiser lower units (not compatible with Verado models). It reduces prying and hammering that can harm housing surfaces and speeds up service jobs on prop shafts and gearcases.

How does the Bonbo puller remove a seized bearing carrier safely?

The tool uses adjustable arms that hook behind the carrier and a heavy‑duty ACME threaded forcing screw to apply steady, centered extraction force. The ball‑bearing head minimizes friction and keeps the screw aligned, which lowers the risk of slipping or side load on the housing. For heavily corroded carriers, applying heat before pulling helps break the bond and makes removal cleaner.

• Adjustable swing arms conform to multiple carrier diameters
• ACME thread screw provides high mechanical advantage
• Ball‑bearing head reduces friction and preserves housing finish
• Heat the carrier if corrosion prevents initial movement

Which engines and gearcases will this puller fit?

This model fits most lower units from 115 horsepower and up across major brands including Yamaha, Johnson, Evinrude, Mercury, Honda and Mercruiser—except Verado. The arms pivot and swing to match a variety of carrier shapes and sizes found on outboards and stern drives, making the tool versatile for fleet service or backyard repairs.

• Compatible with Yamaha, Johnson, Evinrude, Mercury, Honda, Mercruiser
• Designed for gearcases rated 115hp and larger
• Not compatible with Verado lower units
• Adjustable geometry fits many carrier profiles

What materials and design features ensure durability and precision?

Bonbo built the puller from high‑strength steel with finishes that resist corrosion and abrasion in marine environments. High precision machining and hardened components maintain thread life and straight pulling action, so the tool performs consistently job after job. The robust construction also reduces the chance of bending or breaking under heavy load.

• Made from hardened, high‑strength steel for long service life
• Corrosion‑resistant finish for marine use
• Precision threads and hardened bearing contact points
• Sturdy build to withstand heavy extraction forces

How do I use the puller step‑by‑step and what practical tips help?

Secure the tool so the adjustable arms engage the carrier behind its flange, then center the forcing screw on the shaft or removal point. Turn the ACME screw evenly to draw the carrier free, keeping the tool aligned throughout. If the carrier appears seized, apply controlled heat to the housing area before attempting extraction to prevent damage from excessive force.

• Position arms behind the carrier flange and tighten clamp points
• Center the forcing screw on the drive shaft or pull point
• Turn screw evenly; avoid sudden impacts or levering
• Use heat for corroded carriers and protect seals from direct flame

Who is this for: The Bonbo Lower Bearing Carrier Puller is aimed at professional marine technicians, boatyard mechanics, and experienced DIYers who service outboards and stern drives 115hp and above. It’s especially useful for anyone who needs a durable, precision extraction tool to avoid housing damage, speed up maintenance, and reduce the physical effort of removing stuck bearing carriers. If you service multiple makes and models, this adjustable, heavy‑duty puller is a practical addition to your toolkit backed by Bonbo’s 30‑day satisfaction guarantee.
