Thanks for the test suggestions and the piping possibilities. I can't find a cockpit capacity on the manufacturer's website for my boat, so I'm not sure what the nominal time to empty it should be if the pump is running at the full 625 gal/hour. As I mentioned in response to Dana's comment, I'm going to try fully charging the batteries (I'd used them fresh out of the pack as they're supposed to be "ready for use"). We'll see if that makes a difference. Cheers, Philip -----Original Message----- From: mikedaly_at_magma.ca A 180 litre cockpit (like a Solstice GTS, BD Ellesmere or similar) should empty in 4.5 minutes if the pump is hitting its 625 gal/hour rating. Your 7 minute time sounds a bit slow. Mine was a not too far off the rating with the normal thru-hull fitting. Before drilling, just pull the pipe off the thru-hull and test it with the pipe opening at the same height as the hull. That will show the time for thru-hull with no thru-hull constriction. If it speeds up things significantly, then you might get part of that result with a drilled out thru-hull. Your pipe looked corrugated in the photo, like the flexible, thin wall stuff some use for boat plumbing. I used the straight-sided clear vinyl type. That might also have an effect on the flow, especially since the loop you use makes it longer than mine.
