Re: Merc. 600 Hp/sci
 

Pat, What gives. I just bought some 100mph goggles and now you say 90ish! I gotta run back to the Harley shop and trade them in for the $50 dollar ones! :D
What happened to the 1mph increase per 10hp rule?

Re: Merc. 600 Hp/sci
 

Pat, You Are The Diligent One, Great To Know You Are There !!!! Ok, Ponder This, After Warranty I Recalabrate Pcm, End Up With 750 Hp..... How Fast ?????

Re: Merc. 600 Hp/sci
 

The faster you go the more HP per you will need. The formula is not linear...
If you want to go 100mph, and your boat goes 72 with 425HP, how much HP do you need? (100/72)^2 X 425 = 820

Gary, it is tough to say without testing your boat.
Keith has provided us with real numbers to play with...
72mph with 425HP, so with 750HP, maybe 96mph???

Re: Merc. 600 Hp/sci
 

Pat Your Numbers Seem Real World, Anything Over 87-88 Mph Would Be Nice !!!! I Guess My Cruise Speed Would Be 60 Ish ?????

Re: Merc. 600 Hp/sci
 

Why not 80? :evilb:

If you run a 30"pitch prop at 4000 engine rpm, your speed should be around 65mph. :cool:

Re: Merc. 600 Hp/sci
 

PAT 65 MPH ALL DAY, THATS NICE !!!!!!!!! :evilb:

Re: Merc. 600 Hp/sci
 

All day G???...& I thought only Krak got mileage like that!!! :evilb:

Re: Merc. 600 Hp/sci
 

SUPERBASH YOUR RIGHT, SHE WILL BE RUNNING 75 MPH MOST OF THE TIME !!! GULP, GULP........ :evilb: :evilb: :evilb:

Re: Merc. 600 Hp/sci
 

Bad News/ Good News, There Will Be A Delay With Superbabi / 600 Sci. It Appears That Entire Guage Package Has To Be Backed With New Smartcraft System. Analog Will Not Work With New System As It Does With 496 & 525 Hp. Merc. Tech Will Be In Superboat To Dial In All Aspects Of The New 6oo's Working System. Also At Start Up For Prop Selection. As I Said Bad News..........but In The End Great News !!!!

Re: Merc. 600 Hp/sci
 

From what John told me. SmartCraft makes individual guages that will go into every guage opening on the dash. Thank god !!! In my opinion, I think the Merc Racing Rep is coming down out of curiousity. He wants to see how fast a 600 will go in a 30' boat. I think he's going to be in for a surprise ;)
