2005 Johnson 90 HP blows 20 amp fuse

[Bronx68]

My 2005 90 HP occasionally blows the 20 amp fuse when trying to start. What can cause this problem? Is this a common problem with these engines?

After it blows it, does the new one work right away ?? Check ALL the wiring over on both the motor and in the boat. Especially pay attention to the starting circuits.
