I have had water in cable trays and underneath cable trays. Also under the middle bilge well., Scorpion used to fit a panel across keel where the deck drain bilge sits. It makes a flat surface but can trap water. Also water can get trapped outside of the knees in the hull and the drain holes through knees can get blocked (if you have any)
Single or twin engine? single engine boats try to lay to port with a conventional gearbox and prop, especially when planing or excess trim in. I counteracted that by moving weight starboard and centring the engine. Could you move battery or oil if you don't find any water?
