Jim-- Although I have to read "between the lines" it would appear that there are some assumptions made that might not be correct. When you say the seacock was open, did you actually check its flow with the hose off of it? And if that was good, did you check the flow at the pump--and out of it? The bad news is that it is amazing what gets into raw water lines, clogs them and then abruptly gets passed through.. BTW my absolutely all-time worst experience was when I had an eel swim up into an unguarded water intake to the AC pump and die in the line between the through-hull and the basket filter. I have repaired clogged heads but nothing was worse than this job--I seriously considered not using the AC and laeving it there to rot and slowly decompose....i finally just held my breath and did the fix, then dove under the boat and installed a perforated bronze guard over the intake. And forget about the sea nettles--that is a whole 'nother problem. The good news, by the way, is that it will probably happen again! Best--Michael
