Reversed battery cables, now no power

[rlgibson]

I'm new to this forum and are in dire need of help. I have a 2004 19.4 Bayliner with a 3.0L MerCruiser Alpha One. The problem is that, in my desire to get back in the water after winter, I inadvertently switched the battery cables to the battery, got a big spark, and now no power to electrical devices. I've checked the fuse panel and all fuses are fine. I've tried to trace the red battery cable to either a fuse or breaker, but can't locate either. Any help would be greatly appreciated.

There may be a fusible link down at your starter. You may have also blown your alternator.

I've gone to my local boat dealer and have a new starter fuse to install, hopefully that will work. Thank you for your help and advice - I really appreciate it.

On a Mercruiser, there is typically a resettable breaker located on the top portion of the motor...look around, should be a big red button, push to reset...
