can anyone answer this question

[shakinbacon]

I just bought a nitro 170 begining of november. There are 3 holes at the back of the stearn i know 1 is the boats drain. but what are the other 2 for ?

[Buzbait88]

One is your livewell pump in and the other is probably cooler drain.  Not so sure about the cooler drain or if it even has one, but I think thats what my champs holes are for.

One should have a plug and that would be your main drain.  Does the other 2 have a screen over it or removable plugs or what?  I would think the other two are your live well but without see them I don't know for sure.
