Update. All good. So it was like this... 5 minutes from the dock alarm goes off. At the dock I shut off seacock. Pulled the hose, opened Seacock briefly. Plenty of water. Shut seacock. Reattached hose. Observed low antifreeze. Added anti freeze. Scratched head. Why low antifreeze? Maybe the loop in the NEW hot water heater used it up? Started engine. Noticed no water spitting. ***Anyone spot the problem yet?*** Back today and pulled impeller pump. Impeller perfect. Oh wait. The seacock is CLOSED. Yeah that was it. I didn’t reopen it when I ran the engine back at the dock. Hence no water spitting. I gotta calm down. Meanwhile ordered 2 impeller kits and a ss mixing elbow. > Thanks all for clarifications. Jon
