Really would like to change out my motor mounts on my 2019 Pro XS 250. Motor shakes so hard in rough water that you feel it through the whole boat. If I turn around and look at motor it is bouncing fore and aft pretty violently. Kinda scary. The fact that it is shaking the whole boat is too much to want to continue running this boat hard in rough conditions. Is there an alternative stiffer kind of mount that will fit this engine? What kind of costs would be involved if firmer mounts are available? Serial # 2B571507
