Where should i mount the Oil Reservoir Tank?

[Ryaninny]

I have a 1984 CC that was run with premixed fuel prior to repower. In the back if the boat underneath i have the 2 batteries, and pumps. I put an evinrude 200 on her, but i need to figure out where to put the oil reservoir. Any suggestions? I was thinking of moving the batteries to the center console to lighten the weight in the rear, but i’m not sure.. if anyone has some input on location of your tanks it would be greatly appreciated..
