Adding a battery switch

I want to add a battery switch to my 1999 GS201 Fun Deck. Been looking at the Blue Sea Add A Battery Kit with switch and auto charging relay. But I'm not sure whether to get the 65A or 120A version. Any suggestions?

    This will be an excellent addition to your boat.  The model you choose is based on what size amps your alternator is.  Check your engine specs.  If it's 65 amps or under get the 65 amp version, if it's over 65 amps, get the 120 amp.
