29 Fever 525HP Mod Info
I have a 04 29ft Fountain Fever powered by the Mercury Racing 525HP with the XR drive turning a 4 blade 26p prop. Only gas 180 hours on it. I'd like to get the boat into the mid to low 80's. Was looking at the Hardin Marine Stage 2 Upgrade for Mercury 525 EFI. Just wondering if it's worth the $2k or save a little bit more $$ and put a whipple on it for an extra $4k. Just skeptical with long jevity with installing the supercharger. Also wondering if doing a prop change to a herring 5 blade?
Thanks for any help or input!!

Just going by what i have seen at the poker run with reg merc power and no supercharger we always walk by them and there s a few out there And ya low 70 s always with or without passangers iT takes usually at least 650 plus to get up to high 70 s 80 there are a lot of boat owners on this sight with big power can do 78 80

I know the Fountain advertised top speeds are, shall we say, obtained under optimal conditions but the ads claim the 525 equipped 29' will hit "close to 80." My 29 Fever with twin 6.2s is advertised at "close to 74." I've seen 70.5 GPS - slack tide - with 3/4 tank of gas, chain in the anchor locker and water in the tank and ports-potty, boat full of regular gear. (1:65 Bravo drives at 5300 r.p.m.s - I would guess my boat would hit the limiters - and/or run out of h.p. before it would hit an honest 74.) I can see no reason why a 525 equipped boat would not hit 75. Mob_05 claim of 72 with full gear and 4 people seems right to me as I hit about 67 under the same circumstances.

Best I have seen in my non stepped 27 with a 525SC (balanced, 060 over, 9.0:1 MSD ignition and 5psi boost) is 75mph on Livorsi GPS with light load. -2 Imco and 24" P5X 5450rpm. No dyno, but guesstimate is 550hp.
