    1978 merc 70hp. Delete starter help.

    Some of you might have seen my last post on here about looking for a motor for a hydroplane. Rock was nice enough to send an old 1978 merc 3 cyl 70hp along with controls and a spare mid to repair and use in long island.

    Started digging into this thing and would like to run it without a battery. Is there a way to run the electronic ignition without it? Can that be deleted?

    We are trying to strip it down and make it as light as possible, so far we are at 130 lbs which would be okay.

    If you can get it started on the rope, the problem is reliable rpm for spark generating.

    Maybe do a combo set up. Impact gun to get it started-warmed up and then a rope after that???

    I had an inline 6 115 years back and every now and again when I would go to use it, the battery would be dead. Being young and wanting to ski, I started that thing more then once with a rope and a dead battery.

    Will never forget the one time I had to pull start the thing, I had a boat full of people. Told everyone to move as far forward as possible and my buddy Tom thought I was bluffing. That rope left a welt across his back, it looked and sounded like it hurt.

    If you going to rope start, you can always use a small 12 volt lead acid battery like they use in a battery back-up......
