Using 6v deep cycles to start

[Tacklewasher]

I'm buying new golf cart batteries for my trailer this year and am wondering about using my old ones in my boat. How will they handle the starting load from a 115 hp Evinrude?

I'm thinking that the starter doesn't pull enough current to damage a deep cycle and these batteries still have some life to them while the one in my boat now doesn't. Plus I would like to have the extra capacity for the electronics and downriggers etc.

It appears you are powering downriggers and other stuff from the start battery? In that case, I would use the golf car batteries for the accessory load, keep whatever you have for a start battery and use a battery selector switch, VSR or isolator to separate the two systems yet allow the engine to charge them all.

[colour=blue]What ST said.

Question - why does your trailer need golf cart batteries?

It's a travel trailer (or Caravan as you folks down under call them). 8)

I bought a used 400 cu in DIESEL tractor several years ago which had one size 27 deep cycle (only) battery as the starting battery.

I couldn't believe the performance of a battery that was not "supposed to" be capable of such high current.

If they'll start that tractor, they'll surely start your OB engine.
