This trim wrench will fit the trim rod cap that has 5/32" diameter holes with a center to center distance of 1 1/2" (or 1.500). This wrench was designed to solve the problem of removing the aluminum cap from the Yamaha trim rod assembly without destroying it .
The cap has four holes to speed up the process when replacement is needed; rather than two holes like most spanner wrenches.
This trim wrench is made of steel with a black oxide finish. The pin assembly is made up of a 5/16-24" heat-treated Allen cap screw and has a 5/32 dowel pin pressed into the body. This design allows you to replace a pin if damaged.
