I think this series of 280 DA Finally came with a hatch lift very late in production - like '08 or so - I would look at listings in YW and see if you can find one to get an idea - you would likely need a 24" actuator - make sure the motor is ignition protected - hardin marine has a nice setup that has a remote pump - as for making the switch work - my bet is you will need to locate the lead right at the EIM as I doubt there was any wiring to the bilge as it would be years before that was included on the 280DA - the switch pods on your boat were universal, and used on several different models - I know what you mean about the hatch needing a lift, I had an '04 280 and even with the gas struts it was a bear.....and dangerous to close if your toes got in the way! good luck with your project
