All of the above. My personall theory is heat and moisture. Both destroy caps,both in radios and outboards. This is one other good reason not to leave the fishfinder on it's mount,(besides the fact that somebody might steal it.).<br />Like batteries, they have electrolitic material in them,seperated by an insulator.<br />As they heat up and cool, the insulation warps, and they short out.<br />On the pre-80's Mercruisers, there was a resistor inline with the condensor (cap)and<br />the coil. If this is bad or missing (some folks jumped them), the rotor and cap would melt down.<br />Symptoms of a bad resistor are a normal start, quickly followed by a stall.
