Thanks for the replies, would incorrect valve clearances lead to a slight reduction in power and maybe excess black smoke on acceleration?? The 2 aqad41a's in my recent purchase seem to perform well but one will reach 3800-3900 rpm wot and the other only 3500 rpm wot and after the initial plume of black smoke on acceleration the engine that produces less rpm has a faint tinge of black in the exhaust smoke. I've only had the boat just over a month and am dealing with various poor maintenance issues!
