CHARLESTON, SC — Marine Tech Tools, the industry leader in specialized marine repair equipment, is proud to announce the official launch of the Patented 300 Series Pin Wrench System. This engineering breakthrough addresses the most common failure in Outboard trim/tilt maintenance: tool slippage and the resulting damage to both the tool and the trim/tilt caps.
As part of this technological evolution, Marine Tech is formally retiring its legacy wrenches in favor of the upgraded, patent-protected 300 Series lineup.
The 300 Series: A Modular High-Torque System
Unlike standard individual wrenches, the 300 Series is engineered as a modular system. Every wrench in the series—AMT0304, AMT0306, AMT0309, and AMT0352—is specifically designed to integrate with the AMT0170 Protective Sleeve.
- Mechanical Locking: The AMT0170 sleeve locks the wrench in place, utilizing the engine’s own weight to prevent "kick-out" or tool slip.
- Universal Compatibility: One AMT0170 sleeve works across the entire 300 Series line, allowing for a streamlined and professional tool kit.
- Ultimate Torque: The high-strength stainless steel body is cast and heat-treated, featuring our proprietary pins rated for over 200 foot-pounds of torque.

Consumer Alert: Beware of Non-Patented Clones
Marine Tech Tools is aware of third-party sellers using the retired AMT0004, AMT0006, AMT0009, and AMT0052 part numbers to market inferior imitations.
