Blown fuse

[chermac01]

The fuse on my 73 Johnson 115 keeps blowing when I try to start the motor. I had the boat out yesterday was leaving the marina when we hit a "mud bar" the motor quickly heated up and I shut it off and It hasn't started since. The motor wont even attempt to start and when I do try to start it It just blows the fuse. Any Ideas as to whats causing this?

Ok so I bypassed the fuse to see what would happen and It started right up....Now what does that mean?

Did you have the right size fuse in it to start with ??

Install an amp meter in place of the fuse and see what the amperage draw is when starting, mabe a wire is shorting out causing the fuse to blow.
