You really think you had water THAT high in the Engine compartment ???? I'm not saying you didn't, just that it may only need to be disconnected and dried out for a few days.
Mine quit working last winter just sitting outside in the rain in the driveway. I put it in the shop, took it apart and noticed lots of corrosion from moisture on the contacts between the boards. I let it set for a few day and cleaned the corrosion off and put it back together and it worked fine, been working ever since.
You might get lucky on yours too...Then again.....
If you need one, ya might try a wrecking yard....
Good Luck.... "BH"
