You need to find a good boat electrical guy if you want this thing fixed
quickly. It's not an easy problem to troubleshoot over the internet. Lots of
things could be blowing the fuse. A short under the dash. A shorted
instrument. some accessory that was attached to the ignition switch. Bad
coil. bad electric choke. bad ignition module.

I have a 1999 Maxum with a 4.3L Mercruiser. Haven't run it in about 3
weeks couple of weeks and tried to fire it up today. When I turn the
ignition switch to the "on" position, alarm sounds briefly, then my
gauges activate briefly, then everything shuts down...turns out I keep
blowing the 15A ignition fuse on the fuse block (went thru 2 of
them). Trim/tilt, blower, and everything else electrical is working
fine. Battery is good. I traced the wire from the ignition switch to
the fuse block and beyond, and can't find any visible cuts, frays,
etc.

The book shows 15A is the correct fuse. I'm wondering if:

A) 15A is a little light
B) The ignition switch is the culprit

Any suggestions?
