the facts: Purchased boat, put in water, turned over, started ran really rough, bad gas/fuel filter. Next day put in water, ran rough, traveled 6 miles turned off at dock. 5 min later, tried to start, won't turn over. take out of water, wait an hour will turn over. put in water turns over, won't start. next day take to dealer to have carbs cleaned. he says he starts, run rough, fuel additive and let it clean itself out. get home, turn over in yard first time, wait to not burn starter, try again, won't turn over. Lifting idle/choke arm clicks, all gauges work except the trim gauge(?), I've purchased new cranking battery, cleaned wires, checked kill swithc neutral arm (wiggled nothing on key turn) check plugs all connected, 15 and 30 amp inline fuse ok. If neutral switch in control box...how do i get to it?
