I have two new 225 4-strokes that are acting funny at high RPM's 4500 to 5500. Both engines are cutting out at separtate times for just a split second or so. It drops to 2500 to 3000 and then right back up. It sounds like they are starved for fuel. I checked the water separarters and no water present. Any ideas??? Someone told me I may need to add an electric fuel pump to keep up with the demand of the two 225's.<br />--------------------------------------------------------------------------------
