This 3/8" drive impact trim wrench will fit the trim rod cap that has 5/32" diameter holes with a center to center distance of (1 1/4" or 1.25) usually a 2 stroke.
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 and it makes more sense to use all four holes when replacement is needed, rather than two 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.
