Gary, The short answer is yes, in that the higher in transmitter power you are running, the more isolation you may need. Receiver sensitivity and selectivity are also part of the equation as to exactly how much isolation you need from a duplexer.
I think the piece we are missing here is that you have not told us what you are using for a radio, only that you have the transmitter power out set at 25 watts.
