On my norman 23 I have just one 75 amp battery for starter and leisure. Can I link it to a 110 amp leisure battery using a pair of jump leads to give me more amperage?

You could, but there are far safer ways than jump leads.

You could permanently connect it using battery terminals. Perhaps a voltage sensitive relay may be a thought.

Think about how your are going to charge it.... an outboard engine will take a long time to fully charge 185Ah of battery.

Thanks for your reply. Is that the same as a split charge relay? I have a yamaha 9.9 outboard. Would that charge both batteries?

A VSR is a moden and safer version of a split charge relay.

Any charger will charge a large battery, it is just a matter of how long!!!
I don't know the current your outboard is capable of delivering, but I imagine that it may take longer than a day to recharge if you take most of the capacity out of the batteries.

It will top them up, but a lot depends on how much you intend to take out...... If you are looking to run a TV for an hour or an electric cool box you will be unlikely to replace your daily drain.
