Re: BOLT head in the Bilge...
most of the time heads come off bolts because the bolt was loose in the first place. this usually occurs because of poor engine alignment. The stud in there may back right out buy hand if you get the mount off. You can take the weight off the mount many ways. The wood blocks and wedges is most likely the easiest. Have a experienced tech inspect your mounts and replace them if needed carefully inspect your shaft & cutlass brg. then have your engine aligned. It needs to be within .003 tolerance. When running your engine in gear a good alignment will have no noticeable vibration. One trick to checking vibration is to set a cup of water on the cockpit sole if you see concentric rings in the water you have vibration. The better you get the alignment to longer all your machinery will perform & last.
