Raylar kit, or whipple it. Lots of $$ though.

I have a 02 26 with the 496mag and have seen 67 with a 24 pitch 4 blade.

Do the Raylar 525 kit. And cmi sport tubes headers. My prowler runs 72 with a bravo-1 24p
100% turn key.
or find a Mercury racing 525 efi and be done with it.

A blower is the way to go. Bolt on performance and fairly easy install. Easier then heads, cam, intake modiifications and the rest anyways. Been there done that. Go blower.

what rpm are u turning,i am running a 22p bravo 1 @5000rpm
with the 496 mag ho

if u dont mind what did it cost to do the mods and did u do the labor yourself. i am just thinking it may be better to put the money towards a diffrent boat with twins to achieve my goal thanks

Yes it is cheaper and less work to install but how many engines to you want to replace before you get the correct
ecm program? Pistons are cheap but the machine work and labor are not.--------

Im at 5000 rpms.I also have ITS.

BINGO
