06 Heat set-up questions
Well I finally jumped on the Nordic bandwagon. The wife and I bought an 06 Heat open bow. The boat is out of the AZ, Ca, area and likely set up to run that altitude. We are a little higher in Utah at about 4500 ft. Any set-up suggestions on prop etc. Also been seeing a lot of chat on x dimensions etc. Do I need to address anything there. Boat has the 496 ho w/ Bravo x. Thanks

Congrats, welcome! Like to see more of us up in the frozen mountains (enough already).
Try what you got & get some #'s with a GPS and the tach. Go down a size for every 300 rpm you need to gain. So if your at a 28 turning 4200, go down to a 24. That get's you to 4800. Then lab it & you should be money.
I would HIGHLY recommend Merc lab it. They can get it on the nuts if your #'s are accurate.

At that altitude you may need to re-gear the drive to 1.65:1. That boat would normally run a 24" Bravo 1 at sea level, 26" if it were a really good running boat. Run it with a 24 and see what it does. My guess is you won't get near the rpm you need, which is at least 4800.

22 or labbed 24 here in our area with optimum rpm 4900-5000.
I've tweaked 2 Heat HO setups here at our altitude and that's where we ended up at.
You can get away with a stock 24 at the less than 4400 feet lakes such as Powell, Utah Lake, Willard etc. but Deer Creek, Gorge, Bear and any of the 5500+ lakes you will need the 22 or lab 24.
One I just added a little helper to (3.3L Whipple, cam, head work, etc...
) and it's back with a 28@~5300 or P5-X 27@~5300)
One inch spacer helped a bunch here but it was an 05; Not sure if they changed anything in 06...
