I apologize for such a novice question. I have a 99 Mercury 200 EFI 0G803451 on my 99 Ranger. I'm getting it ready to take it out the 1st time since I got it. I use to have the same motor on a older Champ, but the oil system was gone and I just ran premix. I understand what the bigger tank in my boat does, but I'm little confused on the smaller tank mounted on the engine. Do I just fill both up everytime I take the boat out? or does the larger tank replenish the smaller one. What alarm beep am I looking for if the oiler quits working? Is there a minimum level that the tanks should never get below? Thanks for the knowledge
