I am looking at a new Heat
Was considering only a 525
Have been approached with a deal on new one with a 600sci
Any concern or issue on dependability of 600 vs 525? Supercharger?
My last heat (which I regret selling) had a 496 and had trim tabs
This boat with 600 does not have them.
Would it be advisable not to get tabs?
K planes is what I have thought of adding. Thoughts on this?
What top speed might I expect.
Got low 60s in my 06 with 496
I might be back in the navy soon?
Any input really appreciated.

jns,
The 600sci is a good reliable motor. You should easily see 80+ with it. After your warranty expires, it is upgradable to 800+ HP. More important than tabs are full dual cylinder hydraulic steering to the helm. Tabs are easy to add, and will aid the Heat's handling in certain conditions. Mine came with Bennetts, which I switched to single ram Eddie's.
BTW, Merc may be running some specials on the 600s because they are introducing a new stroker 525 in 565 hp. I would still buy the 600. On the list of things I never hear....this boat is too fast, her t-ts are too big, this Crown Royal sucks
......
Glad to hear you are coming back to the Nordic Navy.
Regards,
Steve

Thanks Steve.
No question this would not be too fast!
Does have full hydraulic steering.
How do think XR1lower will hold up?
Will be back with this one or another
Appreciate your feedback.

Oh yeah, I would ask your dealer and/or Nordic what X dimension they are currently using. If the transom hasn't been cut, I would ask for 18.25"s. If they are still sending them out at 19"s or 19.25"s, have them install a 1" spacer for you.
17" or 18" single ram tabs are fine for our boats. Move them out as close to the chines as you can. Like Chris said mount them up, making a small "step", and parallel to the vee of the hull.
The XR will last a long time behind the 600sci. Just change your drive oil frequently, at the most every 40 hours. I change mine every 25 hours, or every time I change engine oil.

I had a 2007 Heat with a 496 and purchased a new Nordic a few months ago. I was doing the same thing as you...600 or 525. After owning it for a few months I am so glad I got the 600. I would have not been happy with the 525. My boat runs pretty damn good but will do the stg 2 kit a little down the road.

Thanks for all of your feedback!
All posts really helpful!
I am feeling pretty good about the durability of the 600. Sounds like a non-issue.
I do want to make sure I get the tabs and will most likely choose to go with Chris's suggestion on the Dana 900's if I pull the trigger on this boat.
Will let you know what we decide to do.
