Guys I am looking for some help. This boat came with a 45 ln thrust motor guide which as you can guess is woefully underpowered. However as the trolling motor is stored in a compartment under the front deck and the is not enough "meat" on the top cap to mount it, I have to change the motor and put the replacement back down in the hole. My question, do most of today's trolling motors use the same mount, so I will be able to do this?

There is a very high probability you will have to drill new mounting holes.  About the only way around that is, if the one you have is not extremely old and the same manufacture is still using a mount with that same footprint, which is not likely.  Also, you will need to verify the one you want will even mount in the same location.  Some use mounts that a almost two feet long, others may only have a small, almost square footprint.  Even then, they don't use a standard hole spacing between different models or makes.  They are not like an outboard, where most all motors fit the same hole pattern.   Besides, it's not really too small.  It's just the mindset of most people today think they need to run 20mph with just the TM.
