Battery Question for older Sea Ray

[streetglider]

I have a 1994 330 Sea Ray Express Cruiser. It is still in inside storage and I cannot get access to it yet (Cleveland, Ohio area). I was wondering if anyone here knows the size of the OEM batteries as I want to replace all 3 and would like to order them. I am fairly certain the prior owner replaced them. I am looking for information on size and series (24 or 27).

Thanks

I would expect group 27 was likely the factory size but you never know what prior owners may have done. I'd be uncomfortable buying new batteries without confirming. Both your battery boxes and your cable lengths can be impacted by the group size of the battery.

There actually is no such thing as "OEM" sizing. Batteries are installed at the dealer level - sometimes in accordance to what the original owner wanted. Plus, given the boat is over a quarter century old, it could be anyone's guess.

Wait and see what you have - or change it up to suit your needs. There's no need to "order" batteries - batteries will be in stock at places that sell that batteries - worst case, they can get them in just a couple days. Best thing is to just be patient - you're not saving any time by doing this ahead of time.

Thanks for the information. I didn't know the dealer was responsible for determining which battery to use. I guess ordering them was not exactly what I was doing. I have scheduled some work to be done and the batteries were a part of that job. The mechanic asked me for the information as he has a source for them.

My guess would be Group 27, but if you have the room for those and are replacing all three batteries I would seriously consider Group 31. They should fit in the same space as the group 27’s.

I will definitely consider the 31s. Still waiting for the boat to be taken out of the building.

Pay close attention to your battery cables. I contemplated 31's on a prior boat and the extra height was enough that it would have required new cables. Not worth that pain for the limited time I spend on the hook...

 

[streetglider]

I will, thanks for the tip.

The correct battery size for your boat is the biggest baddest battery you can fit and afford.

I had 27”s and went to 31’s since price difference was not significant
