Ripper, last year was my first season with our '02 and I got tired real quick of the stock location of the Hippo system switches - I was always trying to see which switch I was hitting and not knowing which switch was what.

So I decided to redo the whole system to give me a better (for me) switch location, bigger ballast bags and quicker fill/drain times. The stock system was sloooowwww

I moved the switches up behind the throttle.

I'm toying with the idea of installing the intake thru hulls below the water line on the transom, if they're installed as low as possible they shouldn't draw in any debris. I'm concerned that installing two more thru hulls on the bottom of the hull may cause prop cavitation at higher speeds. What are your thoughts on this?
I would find it hard to believe that two more thru-hulls would cause cavitation at the flow rates of a boat going through the water, but I would like to hear someone explain it in fluid dynamics terms.



I don't think I'll be going with the reversible pumps because it can get pretty busy in the boat with our kids and now two grandsons. I'm sure it would only be a matter of time before I forget to turn a pump off and burn it out!
I was concerned about not hearing the pump also, but I was told by more than one forum member that you could hear the difference. I am old and used to seeing it spit over the side so I added some check valves and wyes and will be hooking them up like this;

...Moving the batteries up to the compartment under the glove box won't work for me because I store towels, wake boards and surf boards there. When I pull the boat out of storage this spring I'll measure the height under the seats fore and aft of the cooler, hopefully the batteries will fit in one of those areas.
I have two batteries, two amps, the HU's control box and my ACR switch in the hatch area, it does take up some room, but we throw all our towels and clothes right on top.

Good luck with your project!!!!
