Location: one foot over the line | So, I have some new electronics on the boat and no longer trust my 6 year old starting battery, i want to put in a deep-cycle battery with CCA of 750. I cannot seem to get a straight answer if this would be detrimental to my 2005 175hp optimax. Anyone out there that has done this with their opti? Anyone know if this is a bad/good idea? Sorry for beating this one again. Thanks |

A deep cycle battery is not designed for the quick draw down and recharging...they are designed for slower draws and slower charging.
The BEST thing you can do for what you are asking is to pick up a dual purpose battery that is designed both for starting purposes and for deep cycle purposes. This allows you to run your electronics without running the battery down from fishing for long periods of time without running the outboard.
In either case, I don't think you would have any issues of the battery being detrimental to the motor, unless for some reason you hook up the batter backwards, but most motors have a main fuse that will blow before damage could occur.

Location: one foot over the line | Thanks for the response Steve. My local shop finally got back to me and suggested that it wasn't a good idea, apparently there could be an issue with the alternator down the road. I asked them about the dual purpose and they said that would be fine. Thanks again. |
