If that’s the case your boat would fill up with water tooThanks again everyone. I like the air pressure idea. Should be easy to spot any air leak with some soapy water...
Funny, it's a brand new custom Pod and we took great care to make sure the bolts for the motor were sikaflexed and watertight. It's gotta be the bolt holes where it's attached to the boat. Not sure how water would get in there 'cause the front edge of the Pod looks well sealed tight to the transom. Prawning done for now so gonna pull it out tomorrow and start looking...
