I posted this as well in the General Discussion forum.

Simply put, I'm trying to run some numbers of what guys are getting efficiency wise.

I need to know:

hp
gear in drive
prop diameter/pitch
wot speed
wot rpm.

Thanks

Dave,

I may be able to give you an idea. A good friend of mine just bought a 2003 Single Dominator.

Engine: 500 efi
Drive: XR 1.50 w/ Merc ITS
Prop: Labbed 26 Bravo
RPM: 4800
Speed: 74-75 depending on temp and conditions

PS - He is looking to whipple charge it. I think there is someone in the NE who has whippled a Single Dominator 500efi with good results.

Agressor 25,

Thanks very much for the info.

One question. Are you sure he's not turning a 28? If he's turning a 26 4800 r's @ 74mph that comes out to like 6% prop slip.

WOW! That would be great if it were true. If it is, kool!

Thanks again
DAVE

It's an interesting subject, a boat able to perform with single power.

While we're tossing around configurations, what's the consensus on specs for a single Dominator with say a 525 with and without an ITS drive? How would that compare cost wise to a set of twin 496HO's and would it be worth whatever the difference is?...

I looked into it and the 496HO were cheaper and faster and more reliable-drives included, than a single engine 32' of 600-700HP.

Reckless32

cobra, that's what I pretty much thought despite never pricing one that way. Just thought it would be an interesting cheaper alternative than the twin mess/op expense....

Dave F

Cobra,
add up your gas bills and then tell me which is cheaper.

I bought a blank boat. no engine, drive or steering. I will even have to install 5-6 guages. But hey, that's the way I ordered it. with what I spent for what I'm getting, you wont be able to touch it price wise or speed when I'm done.

While I'm at it, I want to say how absolutley incredible Dave and Joe were. Dave especially went the extra mile to help me and work with me. Great people. Even Mitch (Mither T Graphics) was helpful and great to talk to.

I did alot, and mean alot of shopping for used boats. On the computer, sometimes hours a day, the Satly Dog and the back of Hot Boat and Power Boat mags, if there were used boats I was lookin at em.

Anyway, for what I spent on my 03 Sunsation 32, add the cost of my single motor, extention box, hydro helm (I already had the external cylinders), big race E tops, and even a new drive to handle what I expect from the engine, I was in the same ballpark with what it would cost me to buy a 3-4 yr old boat, with twins, build em the way I wanted them and go from there. Granted it helped I already had the blower and couple of other things,but I still had to buy accessories, like; trim pump, alternator, starter,pwr steering pump, raw water pump etc.

Well, that's my take on it. I guess I'll have to see where I end up.

Interesting project Dave, when do you think you'll complete the project?...

Dave F

Reckless,

As a matter of fact I'm waiting for the call from Sue at Extreme as I write. I will be going down there TODAY to pick up my new machine!!!!

I hope to have her finished and running by end of June (my official ETA) but I really hope I can have her done by end of May, first of June.
