I did a bunch of research on these a few years ago. Common answer was 80 under perfect conditions but upper 70's was more realistic in summer heat and normal conditions.

We only got 72 out of it. Now he never trimmed it way out like people are saying and we did find a bad connection on the fule pump.

I just tried this last week. 74.6 with a good amount of trim, in fresh water, calm, clean bottom, and 7/8 tank of fuel. Motors were right at 5000rpm. No way is it going to get anywhere near 80 even running on fumes on the standard props.
Any suggestions for props to get the top end higher?

In fresh water, you will never see 80mph.
My boat looses 5-8 mph in fresh water vs. salt.
That said, a slight chop will break the surface tension and maybe get you another mph or two.
I am not sure what the rpm limits are on those motors but I would think you could squeeze another 2-400 rpm with a slightly smaller prop.
