Bait boat electrical problem

[Night]

I know b/boats are not everyone's cup of tea (I used to detest the things) but, I have had great success with them on big French waters where casting was impossible. Anyway Lad' & Lassies I need some help and advice (please don't say dustbin or rubbish tip). The wiring on my Euro Viper is getting extremely hot when I send on distances of over 100mtrs, to the point where the fuse holder melted. I am not an electrician and have no idea of the cause. The advice I'm looking for is. What is causing the wiring to get so hot and could I rectify the problem myself. Should the repairs be carried out by a professional. Thanks in anticipation.

I would say their is a short somewhere, it will eventually stop working 

take it into a model shop and I'm sure they will just use a electricle meter to find the problem .
