I have been looking at several 01-03 312's with different power options and trying to get honest top speed with these optons

496 MAG (375HP)
496HO (425HP)

I am assuming low 70's with MAG's and mid 70's with HO's?

Does this sound right or does anyone have a 312 with these motors and can confirm?

Also looked at one with 6.2's and told that will hit 70 tops.

Really want to be mid-70's and think HO's are my only option.

Every 312 I'm aware of came with 1.65 bravos. 454 mpi's run 28P Bravos and the 454 MAG/502's ran 30P Bravos.

Would I pick up any top end by going up in pitch? What about running 3 blade screws?

YES, no-one ever thought of that!!!!

J/K: In the 15 years since these boats first hit the market I'm sure someone tested numerous theories, and found they didn't work. Formula builds a heavy rock-solid boat but it isn't the fastest. That boat, with that HP is a 65mph boat...period.

500.. Funny guy!! Lol. To me, the money spent testing props to get an extra 2-3 mph isn't worth it. 65 is perfect... Everyone want to do 80+ on a go fast boat.. This will be my third boat and I am beyond thrilled! The key to happiness is finding contentment, someone will always have bigger, nicer, faster... To me it's the saris dictation knowing I worked my but off to own this boat...

One more question, the boat does not have carpet, any idea where I can order carpet or get the pattern for this boat? Thanks for the help YO!

Couldn't help myself....so many people ask the question. I took Prochargers off the 500's when I bought my 382 then built 540's out of them. The boat ran 98 when I got it and after new/non-blower engines and $10K in props I got the boat back to 86-87. Not esactly money well spent.

BTW: Smaller might actually be faster, 30P Bravos were faster than 32P Bravos on that boat (at higher rpm)

As for carpet, you should already have snaps in the floor. Take it somewhere and have them make what you want. Anything off the shelf will still need snaps installed to match where yours are or you'll be filling in holes and drilling new one in your floor.
