2004, I recall they had something called the Optional Bertha Ballast System back then too. Not saying this is what those switches are for.
If I recall, the 2004s Sunsport and Launch boats had a single-row of switches above the throttle lever.
Below the throttle level and DC outlet was the control panel for the Bertha Ballast System.
I think in 2005 Skiers changed the name and system to Gravity Games.
