What battery do you have for your four stroke?

[fishhrd]

gradyfish22, thanks for the info. I think I will go with 2 dual purpose.

The Yamaha specs, perhaps other motor manufacturers too, want a lot of reserve time - that's just not prevalent in marine so called "starting batteries".
What prevails in starting battery usage today, is the kingpin of all starting battery sales: cars.

I'm not sure why, unless Yamaha cut a deal with Deka or just wants to have plenty of reserve time to get you back to the dock if motor charger quits.

The load be it 4 stroke or 2 stroke is no greater than any car engine load, yet such a high reserve - that car manufacturers don't ask for.

Yamaha chargers provide plenty of power not like old days of outboards, to run the ship's auxs even while idling.

Don't know why such high reserve demand by Yamaha - doesn't make much sense to me being most have at least two batteries in their boat. And with twins, how likely is both motor's chargers to fail?

Obsurd thought it would be - needing two batteries in a car.

Unless you have a diesel. :lol:

Speaking of diesels, I'm looking forwad to see a turbocharged diesel outboard with 2 speed gearcase.

Need some new outboard technology around here, been many years w/o it.

Perhaps all those batteries in our boats will make sense then!

Interstate batteries and battery saving advice

I just replaced the 2 no name starting batteries that my 252 Sailfish came with with 3 Interstate Group29 Deepcycles. I run 175 Zuke 4s's and Zuke recommends 675 CCA AND 180 reserve minutes. The Interetate 29 D was the only battery I found that fit the bill without breaking the bank. It is a 59 lb battery (IMHO the best and only objective indicator of quality.) They list 675 CCA and 210 RM's, better than the top of the line West offer's. I paid $95 each. (the best deal West offered was 150 each) I installed one as my primary starting battery and the other two as the house bank though the two banks can be combined for starting and both banks will charge when underway.

For those of you who hang on a mooring like I do and cant plug in a the end of the day, try this. Wash down before you pull the hook instead of when you pick up your mooring. If you do this you will be charging your batteries on the way home and (potentially) leaving them fully charged. If you wait till your home and then run your WD pump, deck lights and radio while you are cleaning you are leaving the batteries drained and that is the fastest and most common way to kill any battery.

Good luck out there and be nice, it's almost fishing season (here)

BB- where did you locate the 3rd battery on the 252?

 

[busterblue]

alongside the stbd battery on the shelf in the transom under the fish box. It just fit (read "it was a real PIA getting it in there and set up ) with the group 29 boxes end to end. I wanted to put it on the port side (since the helm is on the stbd) but the hoses and valve for the livewell and washdown are in the way. I'll just have to keep a fat guy on the port side for balance. :lol:

 

[BobP]

Half of one the batteies must be hanging off the shelf (??) - didn't think it was long enough across the transom.

Even if I went to trays instead of a box, I like to see all all of the battery supported.

I was thinking of going to trays and glassing in a extention to the shelf, for my 3rd battery plan.

 

[busterblue]

both boxes fit

both boxes fit on the shelf the outboard one is butted against the scupper drain hose and the inboard one is butted against the triangular support that is at the end of the shelf. I'm running a 1989 Sailfish. 252g

The older Sailfish model as a longer shelf than the post 1990s.

I have to extend it about 8 inches.
