I have to get a new aerator timer for my livewells. The one which is curretly in the boat is a RANGER 3 WIRE AERATOR LIVEWELL TIMER. Initially I found what I was looking for on Ebay at Great Lakes Skipper, but it is sold and haven't found one anywhere else. What I need is some information regarding personal experience with other livewell timers on the market today. I'd like an adjustable timer to replace what I have. What are your suggestions?
