OK so finally finished some upgrades #1 was from the Gravity I to Gravity III.
I purchased (2) 400lb bags from a guy locally for $100 last September.
Purchased (2) 1100gph Rule pumps and 3 ballast switches from Ebay, fittings from Maxwake.com, 1" solenoid valves and manifold from Lowes and hose and clamps from local hose supply. After getting started I figured out the switches I purchased would not work so I ended up ordering 2 switches that match the OEM and replaced the covers.

I had the dealer drill and install the thru hull fittings to reduce my stress and maintain warranty. I ended up not running the hoses from the rear to hopefully reduce pressure drop and length (no run is more than 4'). Below are pictures and a diagram for wiring the switches.

You may also notice I opted to put the switches on the dash rather than add another panel, to do this I had to mount the courtesy light switch under the dash. I don't use it much anyway.

Now I just need to lake test
