1988 Johnson 25HP, Machanic says there broken. One rubber mount on each side with a 3 screws holding it on. Before I bring it to him, I removed bottom half expecting to see a broken bolt in the middle of the two rubber pieces but there was not. Not even a hold in the middle of the rubber pieces. The bolt has a flat washer attached to the end, and the rubber pieces are sandwitched between. Are these broken?
