@Windsurfnut, it is a 1994 Ski Nautique with the 240HP 351Ford carbureted with the 1:1 tranny. I had to turn the ball 3 setting way down to stop the surge from 2-3 ball. The 2008 version of Perfect Pass Stargazer which used the paddle wheel and the magnets along with the GPS. I had perfect times almost every time unless it was adverse conditions, then one day the master module blew up after 9 seasons when a safety switch went out. I had to replace the master module. I turned the ball one setting up to level out the ball 2-3 times.
