When I dewinterized my boat I noticed my water pump had a pin hole in the housing. When I removed the pump it has another small pin other the opposite side. It pisses water out the hole. This is the 2nd yr I've owned the boat, didn't notice this last year. Any thoughts what this might be? Seems man made. Any ideas where I can purchase another pump? I've attached pictures below. My boat is an 88 Ski Centurian Tru Trac II.
