72 Super Fisherman Time for a Floor job!

[Bigwave]

Guys I have removed the console and bench seat off the floor.Gas tank is loose.I am ready to sink a saw into the floor.I would like to have some discussion on how deep you set the blade to and how far do I cut to the sides?Do you have a preference of what saw to use?I will inspect the stringers once I do the cut.Keep in mind this boat only was moored for 2 years of it's lifetime and saw the ocean on the average maybe 6 times a summer.Reccommendations on floor products would be great also.
