A couple of weeks ago I became a proud owner of a 1972 Sabre 28 (hull #13). When I brought it in for the winter, we had to go into 2-foot waves and 15 kts wind; when I increased the throttle heading into the waves, I heard a rythmic thumping below. The thumping stopped when I decreased the throttle. A couple of days ago the boat was just hauled out for the winter; the yard called to informed me about it and, as an aside, they told me my cutlass bearing was lose and needed replacement. I checked it myself today, and it seems that it is not the bearing (less than 1/32 inch of free play) but rather the whole strut broke off. The strut appears to have been epoxied along the whole lenght, so I cannot see the metal, but I was able to push it up and down for a distance of about 1/4 to 1/2 inches. The outside (epoxy) did not move and only the part with the bearing and the shaft were moving in and out of the epoxy and creating the sound I've heard when sailing. I'm new to the inboard engines and, therefore, somewhat clueless in this regard, so I'd like some opinions on what I saw. Also, with the strut broken, would the boat move normally under power? The PO was extremely meticulous about the boat, and the engine was replaced only 3 years ago, so I cannot imagine he would not check it out himself during the engine installation...
