Sorry, I was being lazy this morning. Currently I am running the stock hydromotive prop I believe it is a 24P and it has been tuned up. I did not have a Bravo 28P. Instead it was a labbed Bravo 26P I picked up from B Blades. It was a short lived experience as I "rocked it" in the "witches" on Lake Winni 2 years ago during our summer drought. I did really enjoy the overall performance of it though. It felt much quicker to plane and topped out at 70-71 on the GPS. When I say short lived, well I think i had two or three trips on it so I have yet to plunk down another thousand bucks for a replacement. That day also cost me a new lower unit. At least Progressive Insurance kicked in 4 grand, they didn't didn't seem to want to put any extra in for the prop!! Go figure, replacement value and labbed props are a long way apart on the pay scale apparently. If I can make it to the lake more than 8 times this summer, perhaps I will change the prop again. Instead, I'll probably start looking at something with twice the maintenance costs! The resale value probably won't be any higher with a labbed Bravo. The 29 seems to struggle a bit when you bounce on and off plane. If you get some cavitation under you, it seem easier to slow down and start again. she wants to idle or be moving fast just not stuck in between.

Based on what I've read and discussed with Eddie Young, if that 525 has 400 hours - you are at great risk running that engine. Rocker failures, spring failures, etc are common. There are recipes that will fix you up, fortunately. I'd suggest calling someone in the know and getting repairs or advice on the repairs, as they are very likely needed (and overdue).

From what I've been told a healthy 525 29' will run 75-78 light on fuel with driver only and 72-75 fully loaded. I think those number are pretty accurate.

4850 is a bit off for a 525. Mine run at 5400, three sets of props, all dialed in just under the limiters. At your 4850 you are leaving some on the table, not to mention what you are giving up in acceleration and throttle response.
