I am installing the props onmy project boat and was trying to determine the proper torque for the prop nuts.The boat has twin inboards with 1-1/4" stainless steel shafts (7/8" prop nuts).The manual says to consult the manufacturer for proper torque specs but I have not been able to get any info from Silverton. I referred to a standard torque spec table that Ilocated in some engineering reference materials thatI have and it says for 316 stainless 7/8" bolts with 14 threads/inch that the dry torque should be about 200 ft-lbs. I've put a light coating of anti-seize on the shafts so I was going to reduce that by 25% (~150 ft-lbs) as recommeded for "wet" torque specs. Am I in the ballpark on this?
