I really want to mount an auto bilge pump and I cant use the standard "run up the port side locker drain to sink drain through-hull" since I have the extra water tank option blocking those locker drains.

Going up the starbord side has a lot of problems unless I wanted to put a hole on the starboard side of the boat up high.

Looking at it this weekend, I'm wondering why I cant just run the exhaust of an electric pump through the existing manual hosing?

For this to work, I would need to know if the manual Whale pump would pass a presurized flow of water, and also if the electric pump would do the same for a suction.

I've not explored either of these questions yet, but I thought I would see if any one had any other good reasons why this is a bad idea.

thanks - dan
