Need help..
My Donzi has a 454 mag with the spitfire ignition which has worked flawlessly and still may.My problem is intermittent.Somtimes while the boat is at cruising speed,it may hick-up once or twice and clear up.The bigger problem ia also intermittent, when coming out of the whole and reaching 3000 rpm, the boat will lose power and make a thumping noise until I back off the throttle and then it runs fine at lower speeds.These problems just started and seem to go away at random, then the boat runs great through all the ranges. Could this be water in the gas, dirty carb or ignition?
Thanks for your help
