Yea, fixed all that, quickly, many years ago.

Yeah, my friend ordered that 2001 with a 502, then Formula called him and told him they wanted to switch it to the 496HO, according to that phone call their first switch from the 502 to the 496HO. Good deal for him with the closed cooling, no price change. But not sure it was propped perfect yet. It still was an awesome boat, but probably needed a tweak on the props.

Your numbers are because of your setup and its very strong results...

80+ with 525's should be easily attainable. My 353 with 500 efi's has done 80 + numerous times.

the 500 carb boats would universally run 77-78 and the 525's are a fair bit stronger than the rated HP #s would indicate."

to the other poster about the 496/425s.
I have posted a number of times the win with no sacrifices of OTB Bravo 26's on this package.
loaded boat planes easy with tab and 3K, bites quickly coming over and runs 72-73 @ 5k-5050 everyday with persons, fuel, and a plethora of other **** aboard.

everybody thinks big props are the answer to a moderately powered boat, of course having tunnel vision of the speedometer only. No they are not. They also fail to consider the typical everyday load, time to plane and minimum comfortable planning/cruising speed.
The correct RPM "on the power" for the load is the answer and will net you the best overall performance.

Why do say the 496s are pig motors? Meaning slow compared to 500 or 525s?

Of the 3 353's i personally know, 1 has 502 mag mpi', the other 2 have 496 mag ho's. The 502 boat is at 70-71, one 496 boat is at 72-73, and the other is 74-76. None of them complain of a lack of power.

read the post again carefully...
I did not dis the motor

you will find 425's typically over-propped in the 353 resulting in piggish overall poor performance.

80mph with 500EFI's spinning 30" Bravo 4 blades.
Was thinking about trying Hydo's.
