    I have a 2011 Sundeck 240 with just under 300 hours and have experienced the second shifter actuator failure since new. Goes into guardian mode with no warning while on plane. First was in 2013 under warranty. Part is just over $700. Is this a common occurrence? Really surprised that it would fail twice with the low number of hours I have on the boat.

    Are your symptoms anything like I experienced?

    Issues are similar but not exactly the same. I dropped into guardian mode while already on plane without adjusting the throttle at all and it was random as to when it happened.

    Do you get some sort of “shift position” error when it happens?

    No. All I got was error code 61 which when I looked it up seemed to be an injector code. The dealership was able to determine the code was tied to the shift actuator. Just getting error codes is not of much help in the middle of the lake.
