Before I make a suggestion, is it possible you have the numbers (RPM and GPS speed) you have currently with your 14 x 19 aluminum? The best prop, no matter what will be a compromise of some sort, depending on what you are looking for.
I am not extremely familiar with the layout of the 681. Does it have the gas tank forward? (my assumption is that it does). If that is the case, that makes the bow fairly heavy which is good for positioning in wind, but not so much for traversing in rougher conditions.
So...if you can supply any sort of data on that end, I'll do my best to help out..
