Camoo Lower Bearing Carrier Puller For Gearcases
Best for gearcases 115hp and above, this Camoo puller features adjustable arms to fit a wide range of lower bearing carrier configurations. It is designed to remove the bearing carrier oil seal and other tasks where a bearing puller is needed. Ball head design reduces friction, delivering maximum pulling power with less effort. The tool helps prevent damage to carriers during removal, making it a safer choice for frequent servicing. Suitable for Yamaha, Johnson, Evinrude, Mercury (not Verado), Honda, and Mercruiser gearlines.
- Best for: heavier, high-horsepower gearcases where bearing carriers are stubborn.
- Why selected: adjustable arms add flexibility and reduce risk of surface damage.
- Caution: not recommended for Verado gearcases—check compatibility before use.
Bonbo K-812 Boat Prop Puller
This puller is designed to remove 3- and 4-blade propellers, with hub sizes up to 2-3/8″ for 3-blade and up to 3-1/8″ for 4-blade configurations. It accommodates shaft sizes from 1-1/4″ to 1-1/2″, making it a versatile option for many boats. Multiple bolt hole options enable precise alignment, and the guidance suggests tightening bolts evenly to reduce twisting stress during removal. It’s best for varied prop configurations on mid-size boats.
- Best for: mixed prop configurations on boats using 3-4 blade props.
- Why selected: broad hub compatibility and alignment options improve removal reliability.
- Caution: ensure your shaft size and hub measurements match the tool’s specs to avoid fit issues.
Inboard Propeller Puller C Clamp
Designed for 3- or 4-blade inboard props, this C-clamp puller is a practical on-board tool to carry for spare-prop scenarios. It fits 3/4″, 1″, and 1-1/8″ shaft diameters and supports tournament ski boats and other inboards with a 1-1/8″ maximum shaft size. A notable feature is the swiveling screw point that helps prevent shaft-end damage, paired with fine-thread screws to deliver strong pulling force with less effort.
- Best for: inboard sport boats needing a compact, ready-to-use puller.
- Why selected: shaft-end protection and precise adjustment reduce risk during removal.
- Caution: verify shaft diameter compatibility and clearance before use.
K813 Upgraded Heavy-Duty Prop Puller
This heavy-duty puller is built for 3- and 4-blade props, handling 1-1/2″ to 1-3/4″ prop shafts and hubs up to 4-1/8″. It can also work on 2″ shafts by removing an adaptor plate for compatible hubs. It uses thick aluminum pull plates and zinc-plated studs to deliver strong, even pulling. The tool supports a maximum plate distance of 6-1/2″, helping secure mid-to-large props without damage. Use with bolts tightened evenly to minimize twisting stress.
- Best for: mid-to-large prop sizes and hubs approaching 4-1/8″ hub.
- Why selected: robust construction and wide shaft compatibility.
- Caution: requires careful alignment and evenly spaced tightening to avoid awkward loading.
Thorstone Harmonic Balancer Puller Set
Though not a traditional prop puller, this Thorstone 46-piece set covers harmonic balancers, flywheels, crankshafts, and pulleys. It’s crafted from heat-treated carbon steel with oxide finishes to resist rust while withstanding tough pulling jobs. The kit includes 30 bolts and a four-yoke slot, enabling broad compatibility across cars, trucks, SUVs, and many small-engine boats. This set is best for multi-application maintenance beyond just prop removal, offering versatility for engine components.
- Best for: marine technicians who perform broader engine maintenance beyond prop removal.
- Why selected: high versatility and durable construction for diverse pulling tasks.
- Caution: primarily a general-purpose set; confirm specific boat engine compatibility before use.
Buying Guide
What to consider when choosing an outboard propeller puller
- Propeller type and blade count: Check compatibility with 3- or 4-blade props and hub sizes to ensure a proper fit.
- Shaft diameter and hub size: Confirm the tool supports your shaft diameter and hub measurements to avoid over-tightening or misalignment.
- Gearcase compatibility: Some pullers target specific gearcases or bearing carriers; select one designed for your engine brand and horsepower range.
- Pulling power and design: Tools with adjustable arms, ball heads, or swivel points reduce friction and protect drive components during removal.
- Durability and materials: Aluminum or zinc-plated steel components offer corrosion resistance needed for marine environments.
- On-board practicality: For skiers and wakeboarders, a compact C-clamp style puller can be a convenient spare tool.
- Multi-purpose use: Consider whether a harmonic balancer or engine component puller would add value to the toolbox beyond prop removal.
How to use effectively and safely
- Align puller plates with the prop blade set and ensure even bolt tightening.
- Use light tapping with a mallet to help release stuck props, avoiding direct blows to blades.
- Maintain steady, progressive pressure rather than sudden pulls to minimize shaft stress.
- Inspect fittings and threads for wear before each use to prevent tool failure during operation.
