Nimpo,
I would pitch your prop up to a 44" pitch as it sounds like you have a pretty strong engine, expect it to cost you an extra 50' getting off the water, I bet it climbs out 150' fpm better, and gains you around 3/4 mph, But I would expect to see around say 125 less rpm static.
I had a 82/44 on a cub that was a 160 narrow deck from an Apache, that we stuck 170 pistons in .
However it originally had a 82/41 same as you do, it got off good, but thats were it ended, if you didnt run it right up to 2500 for cruise it " dragged its ass in the air..... not cool. SO I put on a new 44 pitch, bingo ! Got off 99% as well, climbed better, cruised little faster, and set right up rock solid at 2350 no tail droopy jazz what so ever, nice tail high Cruise attitude, you will be pleased, (garanteed!)
