Part # for CHARGING SYSTEM FUSIBLE LINK-225hp Optimax

[1991 Evinrude 48Hp E48ESLEI]

Hopefully I diagnosed correctly why my new dual batteries where not being recharged when I was out on the water.....I blew my 100amp Charging System Fusible link?

I have a 2004 225hp Optimax XXL Serial OT862...

I tried searching the web for a replacement, but no luck.

Any help with a part # and where to get a replacement would be great?

Can I make my own?

Thanks
