Re: Pumps do not do what you think

I've always figured that 12V electric pumps are only going to buy me a little time to find/stop the leak unless it's just a small one. Any serious hole is going to sink the boat if it can't be plugged or slowed down.
Most boaters seem to be overly impressed with the "GPH" rating of their pumps without doing the math to find out what that equates to in the much more important "GPM", to say nothing of the friction losses and head.
