Finally reached my goal of 80 mph in my 1995 24' Python. Original motor was a 365 hp 454 Mag and boat would run about 62. Replaced engine with a 540 that I built. Replaced steering with MM full hydraulic. The boat actually ran 83 yesterday and I am really happy with the performance. The boat is a rocket! As most on this sight know, it is a long and painful road to high speed, and I have learned a lot (the hard way).

I want to thank Bob Madera for the cam and the verbal help with my project. He really knows his ship!

How much hp are you running and what type/size prop? How did the boat handle at those speeds? I'm trying to get my 24 Python dialed in and I know I need a different prop but my motor makes about 500 hp. It made 450 hp and 513 tq on the dyno but I changed the heads from stock ported to 320 cc Dart square ports and a Edelbrock intake. 75 mph is more or less my goal but if I can get more out of this combo I want to.

I have not had the motor dynoed, but it should be around 625 hp. I am turning a 25 Mirage plus, thru a 1.5 at 5650 rpms. The full hyd steering made a HUGE difference in high speed handling and stability. I can let go of the steering wheel and the boat tracks straight--best investment on the boat!

thats great,python are great boats

Man buddy that is great happy for you!!!! Now go turn and burn!!!!!!

according to your numbers ya only have 7% prop slip..thats awsome..how it come out of the hole?

Congratulations, 80 MPH is a hugh accomplishment. We should start a thread on the Top 10 things that added no speed. I could probably list 20!

my goal also....will know this w-end

I cam up with the same figure, sounds like somthing is off.

Can't go wrong with Bob, he gives great advice. After you talk to him you feel like he is your engine mentor... what a education you get
