I was going to replace the cutlass bearing yesterday and noticed that the strut is loose. My only problem is how to fix it. On the outside the strut mount and bolts are faired over On the inside the strut bolts are not visible. If I look in the cockpit locker there is absolutely no sign of the strut. When I look in the engine compartment, there is a rectangular piece (I think of wood) fiber glassed into the liner where I think the strut should be. Are the strut bolts under that peice? Can I cut that out with a Dremmel and find the strut bolts under that? When I fixed Natural High, that square piece in the engine room was solid epoxy and the nut heads are embedded within it. I did dremel them out, filled the gaping holes with epoxy again, and then put in longer through bolts so the heads were accessible. The rear strut bolts are hiding just outside the aft most bulkhead (below the control panel). You need to put yourself inside the lazerette upside down to get at them!!

First I cut away the fiber glass that covered the outer surface of the strut. Then, I drilled a small (1/8") hole just in front of and one just behind the strut but in line with the bolts. I measured the distance from the drill to the strut bolts. From inside, I measured back from the drill hole and took a small hole saw and drilled over the bolts. After breaking away the material, found the nuts and tightened the strut. I found the back bolts in a similar fashion but did not need to drill as the bolts were barely covered. I replaced each of the bolts with longer ones, added lock washers and nylock nuts to insure that they would remain secure. In the front, I built up a 5/8" damn 7" x 7" and filled it with additional epoxy. Then I took a 1/4" x 2" x 5" piece of stainless, drilled holes to align with the strut bolts and placed it on top of the epoxy base that I had built up.
