Re: Blocked Raw Water Intake
Did it do this despite an external strainer? or do you have an open intake through hull?
We sucked up a shiner in a similar manner once, enough blockage to starve the cooling system but when we tried to blow it back out it 'leaked by' enough to be ineffective and we ended up going for a swim. We had been trying to blow it back out with the inflatable dinghy pump in 'inflate' mode. This idea may have been more effective with a more solid blockage. Such blockages seem to respond to being 'backflushed' best. If you could've gotten a hose from your pressure water system there to do the same thing that might work too. But I think keeping the critters out of the piping/hosing in the first place is the best defence.
Jellyfish, though, can probably get sucked up through almost anything.
