I just maybe they still are in the BIG HP motors!!

However, how many motors does Zul have in a supercat? How about TMP?
If I was buying a spercat tomorrow, I would probably use Sterling (is any other brand legal by the way, I don't keep up with that stuff).
However, we're talking about a pleasure boat and not a supercat. I don't see what one has to do with the other.

My friends experience with the new HP 525's in the Dragon have shown how helpless we all are when it decides not to run. The myriad of unique sensors and ECM's is more than most of us will be willing to purchase and carry much less diagnose. It's definitely the future but servicing them is gonna be a ***** especially after they've spent a few years in the marine (saltwater ) environment.
Bottom line, EFI is the future, but the future is distant.

I don't think you could go wrong with builders like Sterling,Pfaff,Chief and Zul. I'm surprised no one suggested comparing the components both builders would use and then compare price and service availability. I'd be careful with perceptions and generalities. I can't remember the exact numbers but I think less than 40% of Sterling's motors go to the hard core racers. There was an article about Sterling recently in PRA or Powerboat on just this. I've got 140 hours on a Sterling rebuild of my 800SC's. Knock on wood, but It never fails to amaze me with how well they run with just plug and oil changes. They start easy, run smooth and the temperatures are always on the low side of normal. I've called the shop a couple of times with questions and they've always took all the time required to answer my questions. Just my .02. As I said, I don't think you can go wrong with these two builders.

Like I said, I have no experience with marine efi (other than Merc stuff), but hopefully it will be improving rapidly!
I know there are several sets of efi motors out there now, does anyone have any firsthand experience?
What about whipple, Merc 1075's, and others? Are they working?

I always thought of Sterling as the ultimate in engine builders. I had a friend that used to work there back in the Alcone days and some of the things I heard really impressed me.
I also remember seeing a post of one of the Saber guys that filled a motor up with water on Saturday and by Wed. the motor had been gone thru and dynoed. That was pretty impressive. Unless Sterling is one of those companies that only knows who you are if your spending over 100k a year with them and forgets about the little guy.
I do know I emailed them with some questions on my heads that were supposedly ported by them (old "B" class motor) and never heard from them.

Re: 750 sterling vs 750 Zuls............Again!
What is the price difference between the 2 (or 3 including TMP) the 625-750hp bracket seems to be a HUGE market for for all of us speed freaks without the pocket book to go the 1100-1300 full race setups (or pleasure setups that need frequent rebuilds) obviously it's been discussed that merc has a hole in their lineup here, so custom is the only way to go. Most builders with the exception of Chief and TMP dont even put prices up on their websites. Anyone know why? It makes it kind of hard to compare motors and or builders dont ya think?
Or is it if you have to ask, You cant afford it?
