Replace your Yamaha Boat's stainless steel drain plug o-ring.
O-rings can split, dry rot, and crack over time. If your boat's drain plug o-ring is damaged or aged to the point where it is cracked/dry rotted it will not prevent water intrusion into your boat. If the boat is left in the water unattended this could lead to damage or potential loss of your vessel.
