Which battery cables? 50hp Mariner

Hi all,

I want to replace the old cables running from the battery to my 50hp Mariner 2 stroke, but I don't want to pay the 9 a metre my local chandlers want.

Can anyone recommend a cheaper option?

Thanks,

Will

Go to your local welding supplier and they'll make up a pukka set for you for buttons. Depending on the length of run go for a decent gauge. It makes such a difference. Nik

Thanks Nik. Anything I should be particularly looking out for? A particular diameter etc.

Yep, Machine Mart sell good quality jump leads, one is red and the other black which is nice. They have two types which will do for you, one is 3.5mts x 41mm section and the other is 4.5mts and 54mm section. 23.98 and 35.98 respectively.

25 mm welding cable is the correct dia. I normally pay 28 for 7 metres

Which battery cables? 50hp Mariner

Personally I'd look for tinned cables in addition to the correct size.
Cross sectional area (csa) is also dependant on length- longer the cable, bigger the CSA needs to be.

Sh1t happens

Thanks all. Just phoned local welders and asked if they could make up battery cables from welding cable and the guy had no idea what I was on about. Might have to be Machine Mart then...

I too would look for tinned cable. I would not use non tinned cable for this purpose. But I agree it is very expensive.

I've never used Tinned on the big stuff,on the smaller diameter wiring it makes sense but ...its such a big hunk of copper you'll be fine and will last for many years!
Just go Big don't skimp and it'll be fine
