Weight is a big factor once your prop + slip is maxed for the available HP with the stock 502

Okay guys, need some help to figure out what exactly is going on here.
Yesterday, for the first time in like 2 months, Georgian Bay was dead calm. So, I got to really put the hammer down. With 2 people and just under a full tank of gas, I saw an indicated 78mph at around 5200rpm. Now, here's the thing - I still had about 15% throttle to go. I actually backed right out once I saw the rpm reading because the max on the 502 is 5k rpm. I have verified that the prop is indeed a 25" Bravo 3 blade.
So what prop should I upgrade to? Clearly, there's more top end in this boat, and I'd like to see just how much there is.
I'd also like to know why the boat seems to be very fast for that hull/motor combo. I am wondering if I got a particularly strong 502 from the factory by the luck of the draw.
I must say this thing is just awesome!

Now the weight consideration is a whole different deal.With my race car for every 100lbs it sheds the car will run a 10th faster in the 1/4 mile.Same therory hold true for a boat but the actual mph gain I really wouldn't know.I think you might have more in that engine with labbing the prop.
Oh....speedos are never accurate.

Prostreeter,
Georgian Bay is fresh water and about 500 feet above sea level. Also, the water was calm, wind was zero and the air temp was probably 68 to 70 with no humidity. A perfect day.
Hope to experiment a little more before the end of the season, but don't know anyone with a GPS that I can borrow . . .
