A recent video of an outboard engine survey on twin Mercury Verado 250 HP outboard engines. During the outboard engine survey I discovered a faulty ignition coil (even though the outboard engines made it to their rated wide open throttle range). Bad ignition coils lead to wasted fuel, diminished power, and mis-firing of the engine. This is why engine surveys are so important in pre-purchase marine surveys. <br /> <br />Come see more about my marine engine services at my website. <br /> <br />Capt.
