We assume you are speaking of the bolts in the transom, If so then just snug then up tightly. The compression of these parts is tough, and getting a true torque spec when compressing transom plate, washers and jackplate is not going to be found often.If you make sure and tighten them securely, and shoot for a feeling of what you think is around 80 to 90 pounds, you should be fine.
