    I recently purchased a 1993 SeaRay 250 Express Cruiser and the batteries are dead. Not sure if the correct batteries were in the boat as they were both cranking batteries instead of 1 cranking battery and 1 deep cycle battery. Any idea what the original recommendation/installation was?
    Thanks for your help.

    I used to do deep cycle or dual purpose but now as per my mechanic I just use the big Interstate 1000 amp for everything and haven't had an issue in years. I don't know if you can get Group 27 in your boat but that's what I've been using for house and starting.

    There was no "original" installation. The selling dealer would have installed the battery, not Sea Ray. The important thing here is not what it was... but what do you want it to be? In other words, how do you plan on using the boat when the engine is off? That will dictate your battery type/size.

    Thank you. I just want to make sure the boat turns over when I am in the middle of the lake after 4-6 hours of crushing and listening to the radio

    I'm not sure what crushing is... maybe I don't want to know...

    With that use in mind, a good Group 24 starting battery and at least a Group 27 deep cycle will suite your needs well. A G27 usually fits in the standard trays.

    Sorry typed too fast. Cruising ... not crushing.

    Oh, good. I was worried it was something we shouldn't be talking about! :)

    I gave him the "like" because of the crushing part as in crushing beers

    That was my take when I read it - deck full of crushed cans and some Lynard Skynyrd playing way too loud.
