Ignition fuse blown

[idratherbeboating]

Keep blowing the 15 amp ignition fuse. It randomly blows. Can go boating 3 or 4 times with no problems and than the 5th nothing. Check the fuse and it's blown. Repair shop can't seem to find anything. Any ideas on what could be causing it?

Thanks for any help

What's the engines Mercruiser serial number. Not all V6's are the same, and year doesn't help in finding things.
