Reliable fishing bag with ice/fish on bow of Revo 11 too heavy?

My wife gifted me a Reliable 36"x20" fish bag for Father's Day. The problem is it doesn't fit in my Revo 11 tankwell. It DOES fit on the bow and stays put when i lash it in place. With ice in it, it weighs about 20lbs, more with fish in there. Could you guys foresee that extra weight in the front as a problem? The Revo 11 has a 300lb max capacity, and I weigh about 145.

I keep mine on the stern of my Revo 13 right behind the seat.

That's exactly where it's supposed to be mounted. mount some padeyes up front and clip it in place when in use with some stainless carabiners or snap hooks. It won't be a problem, at all.

I guess a Revo 13 has a bigger tankwell area. When I secure it behind me, the fish bag rides up to the rudder, and I can no longer pull it up. It's also so wide that it covers both rod holders.

Same on my OB with rudder, but I still place it there.  However, my rod holders are accessible on OB.

Time for a kayak upgrade
