Yes! I was wondering about that myself

It already has one, shuts off 4 cylinders during the shift.

Stage 2 typically picks up 400-600rpm so in some cases, larger props work better. Also come on plane much faster with reduction of torque management so its not like before where they struggle below 3000rpm.

But typically dont you raise the rev-limiter to 5800 rpm with your upgrade? I am assuming that the torque management system is programed to protect the NXT trans. It can he a pain it the butt with a heavily loaded boat.

u could afford to loose a couple pounds.

Another weak link is the prop hub you have to use in order to run the #6 props... I know of a few people who have spun prop hubs on NXT's.

Also, with all of the different stages, does the Merc smartcraft/race view still work?

Merc smartcraft/race view still works.

I think I am going to keep the same wheels, which will put less stress on the NXT set up.

After lots of back and forth conversation I beleave you have a great product for what you gain dollar for dollar
(MPH per dollar).

Mark at precision marine said it is a great value.
I trust him totally when it comes to advice about
re-programming

If this is such a bad set up why is no one coming out and saying they are having problems.
I would think now is the time (registered oso people with address and phone numbers we can verify)

The 600 SCI camshaft has become the point of greatest restriction at this point in the testing. The limitations of the 600 SCI camshaft is; compared to the 700 SCI, it has some 18⁰ less intake duration, .056” less lift @ valve (roughly 10%). That being said, the 700 SCI camshaft is significantly less aggressive than the 525 EFI. Cam selection for this series of engines was weighted with a bias toward warranty issues rather than performance.
The very short valve open time and limited valve curtain area builds manifold pressure disproportionately to rate of cylinder fill. In this instance boost is more a measure of restriction than a performance parameter. A swap to a less restrictive camshaft will increase power while decreasing boost relative to output.

Yes, 5850. Yes its in there for protection for people who go right to WOT off idle, never recommended, no matter what

I really don't know of anyone that's had any problems. We've had a few with water psi issues, but that was the same as stock. So there is no negative feedback to speak of.

Mark knows his stuff for sure!
