You might bump the pressure up to say 8 to 10spsi. Then submerse the lower unit into a bucket of water or use a spray bottle filled with dish soap and water. Either way, look for air bubbles coming out from somewhere? If it is coming from under the water pump plate, then that is a somewhat easy fix. If it is coming from the shift shaft seal, the entire gearcase needs to come apart again. If you have a tiny leak, you might get away with just refilling with clean oil and use it next year “as is”! If this is the way you decide to go, check the oil from time to time next year so see if the oil gets washed out.
