Thanks.... That's less than a man up to his knees in water with a 5 gallon bucket.
And a lot less than some of the bilge pumps, although those numbers are always subject to "adjustment".....

Re: How much raw water?
This document has a good chart of flood rates.
http://www.whsyc.org/Flooding/Floodi...olBrochure.pdf
My plan (assuming we are not already in the life raft) is to reduce the flooding and I think from the outside will be easier than from the inside. Most of the hull is simply not easily reachable from the inside.Prometheus

Re: How much raw water?
I agree with RAC and Ralph. I think the "using engine as an emergency pump" idea is good in theory. Except that's not where we live.
The mechanical emergency pump idea, driven off the engine, is a good one. If mounted low enough in the ER it should self-prime if there's water in the bilge. Ralph, is the pump the kind where the means to turn it on is also mechanical, like right on the pump?

Re: How much raw water?
That s why I used to have on one of my 8V71. Mechanical clutch. Not sure what the rate was. It was a standard rubber impeller though which means it is a maintenance item as it will take a set. There are electric clutches that can be activated remotely
I've never used it in anger (terror lol) but it empties a bucket in seconds at idle.
Discharge is through a dedicated above the waterline thru hull.
A remote switch is a good idea."The older I get, the faster I was......."
