I have owned 4 mercury outboards 2 verado 300 and 2 15hp Mercury bigfoot. I had problems with all 4. OCM on the first verado. Right from dealership. Lost all oil in the first mile. Lower units on the bigfoots. All were under warranty but I was without my boat for months. I won't be buying Mercury motors again. My advice, get the extended warranties and roll them right into your payments. You will need them down the road.
