Dave, I'm surprised a few cups of antifreeze would get to the engine by the way you describe. The point where the raw water shoots into the exhaust should be angled to enter the exhaust and not the engine. Before it backs up into the engine, your hose from cockpit to engine, raw water strainer, the heat exchanger, exhaust hose and muffler needs to fill first, before it can back into the engine. That's a lot of water to move. Also, remember if the engine was stopped, the exhaust valve is closed on 3 of the 4 cylinders, so the intrusion is limited. Starting the thing might blow it all out?
If I remember right, I can open a water hose under pressure to my raw water pump but it doesn't pass through the impeller until I start the engine turning. I suspect your pump impeller may be worn and need replacement? I'm hoping it is not hydolocked, but not starting for some other reason probably electrical, key off, switch off, batteries turned off. Did you hear the solenoid click? Did the starter whine or hum at all?

Thanks all for the words of advice! I'm going to be a wreck until Sunday when I can get there to try to resolve this situation. So here's how I managed to do this: I was attempting to winterize the engine, boat still in the water. First I just ran the engine normally for a while, maybe 30-45 minutes, while I got everything ready. After I shut it down and closed the raw water intake seacock, here was my winterizing plan: 5 gallon bucket sitting on the cockpit sole, filled with pink antifreeze. A length of hose running through the opening port in the aft cabin from the cockpit to the engine compartment, connected to the raw water side of the water strainer. Seemed simple enough: I could start the engine and watch the level in the bucket, adding more if necessary. My big mistake was attempting to prime the hose with antifreeze. I was just using a small cup to pour some antifreeze into the hose from the end up in the cockpit; no pressure. It didn't occur to me that the small height differential would be enough to push water past the raw water pump into the cylinders, but apparently it did. I didn't realize what had happened until I attempted to start the engine, and it wouldn't turn over. At first I thought the batteries didn't have enough juice to restart after my cold startup a few moments earlier. I stabbed the button a couple of times, and then it dawned on me. I went back down below and disconnected the exhaust hose from the manifold riser, and sure enough, pink poured out. Perhaps I'm having a stupid moment but I'm really still scratching my head over this. I really didn't pour much down the hose, just a couple of cups. But I'm actually somewhat hopeful that the contents of the cylinders is mostly antifreeze - should give some corrosion protection I'm hoping. Until sunday... -Dave _______________________________________________ Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
