hello I'm helping someone sort out the mess that they have purchased... Buddy of mine bought a boat without trailer and sight unseen for dirt cheap... now we're in wiring hell. engine has great comp. and cranks over but no spark so I need a very basic wiring diagram for this motor from battery to starter including the ignition and the throttle/neutral safety switch and alternator. Can leave out the bilge pump, nav lights, blower, horn and the gauges, as well as all the rest of the cabin acc's as I'm just concerned with it firing and the prop turning when put into gear. I intend to put the engine blower motor on a separate switched circuit so don't worry about that. all the rest of the lights and pumps and such my buddy can sort out once he knows it runs and will commit to purchasing a trailer to get it off the water proper like because otherwise we're just going to cut our losses and drag it onto a flat bed and take it to the dump.
