If this does not work I am going to try a battery combiner and
let it charge my deep cycle trolling battery too.

that sounds like the easiest and best approach!

If the outboard can only drive 5 amps it shouldn't take much of a battery
bank to provide that kind of load. If you have the current to spare, there
is no reason not to charge the trolling battery.

I suspect that the higher voltage is because the new battery is fully
charged, where your previous battery was always at some level of discharge.
An experiment you might want to try would be to drain the battery a bit and
then hook it up. Hook it up to your trolling motor for about 20 minutes and
then swap back.
