I have an 89 3.0 mercruiser with a snapped bolt on the shorter nearer side. I have been reading that these will continue to snap unless the starter is harnessed by a "OEM" starter bracket. I dont have a bracket, and this particular motor has less only 30 hours on it. Did they all come with brackets? Where can i purchase this bracket? Should I tackle the extraction? I am fairly mechanically inclined. Thanks for your help. This is my first boat and I am green and wet behind the ears...
