After 3 weeks of agonizing over which one to purchase, I set out early one saturday morning with my mind made up to get the outback. When I arrivied at the dealer, the owner who had been working with me for the past 3 weeks was busy with another customer, so I had time to ponder my decision. Upon talking with a few others that had either the outback or the revo, I was rethinking my decision. They both have very strong points in their favor. To make a long story short, I ended up buying the revo. When I got it home & started trying to figure out where & how to mount rod holders, fishfinders, etc, it left me thinking I should have brought the outback instead. I guess the only solution we be to buy both if I could afford it, but since that is highly unlikely, I will always be questioning my decision.
I have owned both now for quite a while. Again, if you fish deeper water over shorter distances, the outback may be a better choice. BUT, if you are talking about a real kayak, one that is quiet, paddles long distances well, fishes well, the Revo is the no choice winner.
But it like this. I fish the flats around oysters, shallows, mud shallows. I venture into the gulf and up tidal creeks. I have both kayaks sitting there in front of me on the trailer. Only very rarely do I even consider grabbing the Outback.
However, If I was going to go fish a lake or a pond I would grab the outback as my first choice.
No boat is the best choice in all circumstances. The Revo is simply a better Kayak for most of the time and especially for stalking fish on salt flats.
As far as mounting a fishfinder, The best solution for either boat is to mount a finder on a pole that fits down into the sail mast. Then it is removable, out of the way, etc.
I will upload a pic of my revo so you can see solutions to mounting problems when I get a few minutes.
