Tested my motor today (1988 XP150) after replacing my water pump/impeller and had great pressure through tell tale and it shifted well. However, when I pulled the boat out of the water I noticed a considerable amount of water draining from the 3 weep holes towards the top of the lower unit right below the cavitation plate. I’ve had this motor for 8 years and I know water always drains out of these holes but today felt like it drained for 30-45 seconds when in the past it’s only been 10-15 seconds. Is this hurting anything if the water pressure is good and tell tale is strong?

Do these motors fill up with water to the waterline through the weep holes or do I need to pull this lower unit and figure out what I did wrong?
