If the lifters don't pump back up after a short period then the lifters may need to be replaced or rebuilt.

The reason I asked to check the oil level was to see if it had gone up. It it went up then something leaked into the block.

Does the motor have oil pressure? The lifters need oil pressure to fill them with oil and pump up.

i started the boat to re winterize the other day facing the motor the right side was doing all the clacking,i let it warm up a little then pushed the idle up to 1500 rpm and the noise stoped on the right, a little while later the rear lifter on the left started clacking will leave over winter and see what happens oil presure is normal
