New Thermostate part number

[BigAL0213]

Need to buy a new thermostat for my 2004 260 DA with a Merc 350 mag. Anyone know the part number?

You should be able to get the parts manual for your boat straight from the Sea Ray website. Make sure you get the retainer ring and gaskets when you do buy the t-stat (assuming your motor has those items).
