i've had such great luck until now with getting this boat going. havent bought a battery for it yet. i use my vehicle battery. but tonight when i tried to turn it over all i got was a clicking sound. after a few turns of the switch it tried to start but it keeps on just turning over. even with the switch off. unhooked battery to get it to stop cranking. as soon as i try to put the cable back on the starter starts to turn over. unhooked wires from the key switch and same thing.is this my relay or my starter? if its the relay how do i know which one? theres 3 all setting close to each other. this is a 2.3 ford in a 88 glastream. omc cobra
