Hey apache, who built the motor for you, I am still looking at few builders now and in theN/A 632-650ci range. Is that dynoed HP? what was the tq especially around 3500rpm. Great looking piece and to echo what somebody else asked w or w/o exhaust.

Let's put that pretty engine in your truck (the back), drive an hour south and lets slip that puppy in my Daytona- very sweet package.

Is that a local shop? What will it spin to- 6ish? How's the idle and driveability?

Good luck!

the idle is fine just like a normal motor with a lobe to it, you would have to see and hear this motor to appreciate what it does.

Joplin's not too far, I'd buy fluids and consider it a good investment in future boating decisions. Let me know!

Interestin. I upgraded from an 500 EFI with a XZ and hyd steering, to a 575 with an XR on the new ITS transom system for $12K.

I think my motor will have more appeal in the long run, nothing aginst KE and if this was my last boat ever I might consider them, but when I go to sell my boat I feel the blue motor and the ITS will be worth more than a KE setup.

Just mho

That’s all right Fresh water cooling no temperamental SC Motor to deal with .and big Power !

Too Old

I only have experience with with half of your question but it would be interesting to compare. Both my 575 SCi's have just been rebuilt. Anyone have some new KE 675's they want to trade?

Yeah, no kidding...
