### ⭐⭐⭐⭐⭐ Fits Volvo Penta SX-M tilt cylinders
*by B***S on September 21, 2026*

Worked perfect. Used on Volvo Penta SX-M tilt cylinders. Pins were a little small, but did the job.

### ⭐⭐⭐⭐⭐ Great spanner
*by R***N on July 29, 2026*

This worked great when replacing seals on my hydraulic steering for my outboard motor.

### ⭐⭐⭐⭐⭐ Quality Cap Removal Tool
*by J***R on December 18, 2025*

If you've ever worked on your trim and tilt pistons, this is a must have tool. Tried other cheaper, inferior tools with no success. Pins would either not fit at all or would bend and break. This tool made easy going of loosening and removing the cap. Pricey but quality and effective.
