I don't have a picture of my boat in action, so this will have to do. its a 2005 starcraft 221. it has a Volvo 3.0 liter. that makes it different and I like the Volvo.
I run garmin ffers too. I have no knowledge of the 740. my unit is about 8 years old and never had a problem with it. try going to the hull truth and look in the electronics section.
