Putting in a recessed trolling motor tray and will need to take out foam for it to fit in... was thinking of spraying around it with the the 'GREAT STUFF' foam that you buy in any lowes or home depot
anyone know?

It might not be exactly the same but I believe it will be as good. Use care, as this stuff really expands. We used to make it in our shipping department with two liquids, I forget what they were.
If you do decide to use Great Stuff i would recommend the low expansion one, that is used to seal and insulate around windows and exterior door jams. The regular Great Stuff expands alot, i have seen people put it under Jacuzzi's to attempt to hold them in place and when they came back the next day the Great Stuff literally lifted the Jacuzzi off the floor 6 inches.
Honestly i dont think there is any reason to replace the foam, is there room to run the drain for the T.M. tray. Just take out enough of the original foam to get the tray in place and get the drain line in, to get the water away.

What kind of boat is this that there is foam underneath where the T.M. tray is going.
2000 Champion 203
The stuff used by boat builders is very high% closed cell foam, available on-line at
Urethane Foam , Expanding Marine Polyurethane Foam
Check the home depot stuff to see if it says it's open cell. If so it will absorb water readily.
So many honey-dos . . . . . so little motivation
That is what i was trying to get at with my previous posts, some of that foam is not suppose to get wet, but if this foam is under your T.M. pedal i am guessing it has gotten wet alot so far.
I think we have a winner! Read this please..
Differences Between Latex and Polyurethane Foam Sealant
There are two key differences between latex foam and GREAT STUFF™ polyurethane foam sealant:
Latex foams are typically "open cell" and, as a result, can take on water. In fact, the same properties that allow you to wash latex foam off your hands with water also mean that the cured foam can absorb water. This can cause wood rot or deterioration in areas where wet latex foam is next to wood, such as a window frame. In contrast, GREAT STUFF™ is a closed-cell foam. It forms a water-resistant outer skin when cured. Latex foam does not expand. GREAT STUFF™ expands to thoroughly fill all voids and cavities making it an ideal air sealant.
I would not worry about replacing that small amount of foam.
