Marine Tech 300-Series Pin Wrench (35mm)

The AMT0309 is designed to safely remove and install seized large trim caps on Yamaha V6 and Suzuki outboards without damaging the aluminum housing. As part of our upgraded 300-Series, this tool is crafted from polished marine-grade stainless steel, handles over 200 ft-lbs of torque, and is backed by a Lifetime Warranty. To prevent tool slip—which can strip pin holes and damage cylinders—this wrench features a hex-body design that locks perfectly into the AMT0170 Protective Sleeve (Sold Separately). By resting the outboard directly onto this sleeve, the engine's weight securely traps the wrench against the cap, ensuring safe and precise removal under heavy breaker-bar pressure.

Stop Wrestling with Seized Caps — This USA-assembled, stainless steel 35mm wrench fits all Showa-manufactured Trim/Tilt units, including Yamaha, Suzuki, Honda, Johnson, and Evinrude. Equivalent to Yamaha Factory Tool YB-06548 and OMC Johnson Evinrude Factory Tools 324958 and 0324958, our heavy-duty gear ensures a precise match and a damage-free repair for your rig.

Expensive But Well-made .

The wrench is well-built and worked very well for my 2006Yamaha F150. In my case, the outboard has been used on a freshwater lake since new so I didn't have any corrosion to deal with. A little tricky to use since one must keep the AMT0309 very flat against the cylinder caps while simultaneously turning the cheater bar used on with the socket wrench. In the end, the AMT0309 made short work of cap removal and installation.

AWESOME TOOL for the average do-it-yourself mechanic

Before buying this tool from Marine Tech I purchased several pin wrenches/spanner tool wrenches from Harbor Freight and Home Depot to remove the End Cap on my trim/tilt system and those tools did NOT work. Save yourself the time and money and buy this tool first.

Well made and works perfectly.

Used this to service the trim/tilt cylinders on my 1999 OX66 Yamaha. Impressively well made tool. The tilt cylinder cap came right off using this tool after 25 years of being together.

Marine Tech has fantastic products and customer service.

I ordered this product anticipating replacing the tilt/trim seals on my boat as a precaution. The tool arrived on Thursday, and this Sunday the tilt/trim failed! Perfect timing. I was able to break down the tilt cylinders and rebuild them in about 3 hours. The tool was fantastic, and the instructional video was a big help also.
