Hi all.
I have a 50hp Mercury 2 stroke and the battery has started to fail. I am looking to bite the bullet and install a dual battery setup but need some guidance. I would like to have it wired so that one battery can do the motor and the other do all other things.
The battery that is failing is a Quicksilver Marine Starting Battery 450 CCA 100 RC had it roughly 6 years.
I am not sure what size alternator is in the Mercury (16amp maybe?)
I had a look in Road Tech Marine today and the young bloke that was on couldn't really steer me in any direction but I came across these

I already have a 1,2,1+2, off isolating switch installed on the boat simply to shut the battery off when the boat is parked up.
Would 2 x 60AH allrounder batteries be suitable for motor and house or should I go cranking battery for start and deep cycle for house?
Do you still use the isolating switch with the VSR or just use one or the other?
Any help would be greatly appreciated..
