Oh, that's interesting - I have one too, but it's a legacy switch from the previous Mariners that needed it for the Big Lift (for trailering). The current Etecs do the job themselves, so I think it will be the new Horn switch/button..... I guess your's raises the engines to their max height - possibly not the best position for trailering....
Thanks for the quick reply and yea, that would have been my guess - I just wondered if there was something more to it. I suppose it would be very useful on redbays were you use the "trolley" launching trailers and need to quickly turn off and raise the engines as you exit the water.
