Reviews for 38mm x 4mm Pin Wrench (AMT0304) - Replaces AMT0004

Tool was very useful removing the seal caps on my 2015 Yamaha 250 SHO. First time they were removed in 10 years with no issues. I mostly run freshwater in south Louisiana, but I always flush and rinse the motor when I run in saltwater.

This tool made changing the seals on my trim shafts incredibly easy!! It took the cups off the tops of the cylinders with ease. I was able to do all 4 of them on my F250's in about an hour.

Best quality. Do not use the two pin simple wrench that is with some kits. Buy this one and do the job right with a quality torque wrench when tightening up.

Good quality product. Fit the Seastar fittings perfectly.

Delivered on time, even got a Cuzi with it!! I have not used it yet, but being an Engineer, I can see that the quality is top notch.

Best tool for the job, perfect fit for a DIY fix. I'm ecstatic that I have made this purchase and it saved my trim caps for re-use after replacing the seals.

The Marine Tech people were awesome. I ordered an spanner wrench and seal kit over paid. They called me to tell me this and used the over pay to send my kit overnight. I run a charted business and time is critical, so their thoughtfulness and discipline to go above and beyond was literally a time saver. I highly recommend using Marine Tech. Good quality parts and tools, made this whole process a breeze.

exact fit. makes the repair work so much easier and it arrived quickly
