Motor fires right up and idles great. When I throttle up there is no power there. This happened before and it was the fuel lines deteriorating. That problem was fixed and the boat ran good for a year. Filters are clean lines are good. going to check spark but don't know what else to do. maybe the screen in vse tank? Any suggestions or ideas?
