X-Dimension
 

Some recent talk of X heights...

Mine from factory is 19 1/2.

Re: X-Dimension
 

Please correct me if I am wrong, but I understand that the X-Dimension is the distance from the center of the propshaft to the center of the crankshaft....

Re: X-Dimension
 

DragonFire,
It's measured from the center of the prop shaft to the running surface directly in front of the drive.

Thanks Lofty.....

I've had that eroneous info in my head for8 years....

Re: X-Dimension
 

It is center of crankshaft to running surface. Otherwise 19.5" would be pretty high! It is usually around 18+"'s

Re: X-Dimension
 

Dave....from what i have heard there is about 3-4 to be had with -2 Sportmasters and herring 6 blades.
This is an 06 42 that has the power and X height to run 92mph....this "IS" the best setup 42 Ex out there.

Re: X-Dimension
 

Back4More, you said the word "power". It is my understanding that you need extra power to run these ultra high x-dimensions. I was told that simply raising the x-dim on a boat like mine (HP500 powered) will not gain speed unless I add HP. Is this true?

Re: X-Dimension
 

The term "power" was meant that this Ex is a 92mph setup with the 600SCi's

Re: X-Dimension
 

That is 5 mph better than my Ex 525's. GPS before it broke was at 87. That's alot of coin for 5.

I am already wanting to go faster go figure, need to save up some coin and get in upper 90's or 100 sooner than later. :cool: Sounds like TomCat Rtech is working on something for 525.

Re: X-Dimension
 

You went so fast you broke your GPS? :p

Re: X-Dimension
 

Downtown,
Thats 87 with no load and low fuel. My guess is that you run 80-82 loaded? 93 with the 600's was with almost full fuel (3/4-7/8 on gauges), on flat water, that's more than a 10 mph difference.

Stock power 600's with full warranty, definitely worth the money in my book.

Re: X-Dimension
 

I have the 600's in my 42 X. Love 'em. Time to sell it if somebody wants a great deal. about 18 hours on it..........

Re: X-Dimension
 

The Kman knows! :cool:

Re: X-Dimension
 

correct. I do not know what speed with full or almost full. My GPS was broke after 1st trip and I never fixed it till Aug.

You and your-brolaw know what speed is for every new Fountain out there. :D I'm just small potatoes :drink:
