I pulled my boat out of the water today. When I was putting my transom saver on I trimmed the motor up and it stopped. I thought I heard a small pop, (I am not that sure) kind of like a fuse blew. My trim will still go down, but not up. I tried the trim switch at the throttle and on the motor. Neither one will work. The deep cycling batteries are just about dead, but I thought the power source for the trim came from the crankin battery. If someone knows what may be wrong please let me know. (2003 200 EFI Merc.)
