2005 90hp tohatsu charging capability

Hi i have dont a few posts and thanks to everyone that has helped. The boat is back in the morning from having the engine fully serviced. I am thinking of a 2 battery system so i can isolate the starter battery. Would my 2005 2 stroke tohatsu be capable of charging 2?

Thanks in advance will

Not sure why you'd need a 2 battery system? Unless you're running radar, you'd have to be at anchor for days with more electronics than would fit most consoles to drain the battery enough to not start the motor.

Without the figures to hand,You should be ok charging them as long as it wasn't 2 huge truck batteries.

Okay thanks for that. May be okay then. Only got a vhf and fish finder. Then i just have the bravo 12v pump for blowing up the tubes and inflatables but can leave the engine running while i do that i guess.

Cheers Will

What about an intelligent split charging relay?


Once the engine battery is fully charged itl charge your AUX battery.

That way you are only ever charging the one battery.

Hi that sounds good. Do you know where I can look at one? Which website and which do you suggest?

Thanks Will

Just had a look at them on eBay. They look like the answer to me.

Blue sea do a very convenient battery add kit as well. There's one on ebay here:

BRAND NEW - Blue Sea 7649 Mini Add-A-Battery - 7649 | eBay

but it is from the states. Don't know if anyone in the uk sells them, but this is what I was going to use until I found out my engine could charge two batteries by itself. I did get one of the switches in the kit though.
