Cool - looks like you'll be in business shortly.
The new Water cooled ESC seems to be working Great. My system no longer shuts down due to heat.
I drove Lisa several times last week and it was great (slowly making my way out to the bigger waves.). My Caulk seal came loose between the prop shaft and hull so I am working on a new fix for that as well.
I also took a garden hose and shot water into the intake port to try and get an idea of water flow through the system. I would like to see more water flowing so I am going to experiment with the arrangement of the feed hoses and try to reduce the number of arching curves.
One last thing. You can also check for hull leaks by using a technique similar to the one used to find motor capartment leaks.
1) Remove the deck
2) Completely screw in 3 out of the 4 screws into the screw holes - this is with the deck removed.
3) Place a long water hose into the 4th screw hole - the one without the screw in it.
4) Place the hull into the water up to the hull seems
5) Blow air into the hose.
