hello i have a 2002 bayliner capri 175 with 3.0 mercruiser. i recently ripped out another 3.0 engine from other boat and put it into my boat. its running pretty good, the engine was a 1987 with points ignition and bigger alternator. but i swapped over my electronic ignition, distributer, wire harness, etc. my 2002 alternator died, and my question is, can i use the 1987 alternator with my upgraded electrical system. like i said, its much larger then the newer one. somone told me there maybe a volt regulater or somthing inside the larger one, and the newer one has it somwhere on engine. is this true? i would like to take the boat out this weekend but dont wanna mess anything up. any info will be much appreciated. thanks, nick
