Fished a tournament out of my 2006 198. My partner and I had a great tournament. Both caught our limits. However I have never lost a fish in this boat but we ened up losing 3. One I hooked deep on a rig so that did not surprise me. He lost two quality fish.
Here is what I did to try and prevent it from happening. Filled my livewell at 5:00 am with cool water. We had our first keeper by 5:45 AM. I ran the hydro air all day long on manual. I even put ice on the fish using gatorade bottles frozen solid. Even used catch and release. My partner had a Triton and said he could recirculate water all day long. If I leave my pump on manual I will over fill the livewell. I did put it on auto. after he suggested I do so. Usually dont do this.
I also thought you would be better off not pumping hot water back into your livewell so I very rarely use auto on my aerator unless cool weather and water temps.
All the other fish seemed to be healthy and very lively. I think the heat got to them as we battled it all day.
Hate to kill any fish but I noticed several other boats had the same problem and all different makes.
How do you guys and gals deal with the heat? If there is a better way I will change and do it that way.
