My information is that like my 38 the 33 has only has a single 30amp fuse and in my thinking a 4 fuse system would be more preferable as separating the systems would be an advantage.

This is personal precedence only.  I am not a fan of using the spade connectors that it appears that fuse box uses.  I prefer the ones that have a bolt to tighten the wire down with.  I know the spade connectors should be good enough but with the ones that use a bolt to connect the wire there is one less crimped on part that can get loose, corrode, be sized wrong etc.  Anything to lessen the number of connections is a good thing.  

I also like ones that have their own dust cover included.  Not needed but its a nice bit of protection depending on where it will be mounted.
