Re: question's about 01 Merc 575
Quiet Storm:
What hydraulic cam(s) did you go to? How much HP/MPH did you gain? Did it require reflashing the ECU(s)?
I am contemplating replacing my stock cam. I'm glad to hear from someone else who's already done it on one of these motors.
Regards,
Steve

My only concern with this upgrade is getting the ECU reflashed properly. I've had AZSM do it once, with their boost kit, and it works fine. I've also added a Whipple intercooler, and cranked up the boost to 7PSI. It's working very well.
Thanks for your input.

Racin,
Thanks for the info. I think a Crane in the 731/741 range is the way to go too. Have you heard about any of them breaking at the distributor gear? Somone on here was talking about that?

I also lost a distributer gear before the rebuild.

Racin and Quiet Storm,
Thanks for the information! Quiet Storm those motors look awesome with the yellow blocks (to match your boat) and factory blue.
Have you tried or considered an intercooler? The Whipple really woke my motor up.

I was planning on putting intercoolers on but Arizona speed said that I didn't need them because I wasn't adding that much hp. They said the intercooler would take about 50 hp and I would need more boost to compensate for them. So if I leave the pulleys alone, it's safe just to leave them off. I'm only running 5 pounds of boost but higher compression. It wasn't easy but they did talk me out of spending my money.
Thanks
Roger
