4-Piece Pin Wrench Master Set (300 Series)

The Marine Tech Tools 300 Series 4-Piece Pin Wrench Master Set is the complete professional solution for removing hydraulic trim/tilt and steering end caps on Yamaha, Suzuki, Johnson, Evinrude, and SeaStar systems. The patented sleeve-and-receiver system locks the wrench into the cap, eliminating the twisting and slipping that makes stubborn caps so difficult to remove. Apply a breaker bar, a 5-foot pipe, or an impact driver with confidence — the wrench stays put.
