My guess is probably not but it's simple to know... if it works, no. If it
does not, yes.

While the battery would have small holes in the caps to allow for gases to
vent, I doubt much, if any, water would enter through these holes. Pop the
covers off and see if the battery is filled up to complety with water. If
so, I'd remvoe a little out of each cell. There is usually some type of full
indicator in the inside.

About the only "damage" I can see this causing is that the water contains a
very small amount of deposits which will stick to the plates in the battery.
But I'm guessing that the batter was almost completly full of water when
submerged that very little lake water would have entered (again, if any).

If your trolling motor battery was accidently submerged in about ten feet
of
water for about 15 minutes, would it cause it any harm? It's not sealed it
has caps
