The first challenge, was purely a personal preference, the engines {twins} sounded like a Cummins diesel when coming on plane! and that was with no mufflers thru 4 inch tips. At speed outside of the boat 5900rpm they sounded good but at idle and getting on plane they sucked, The second issue was the powerband, not a real good mid-range hit and if you didnt prop the boat for 5900-6000 rpm instead 5500 or so you lost a lot of top end power, kind of like a 2.5 merc, the 3rd issue was outside temp/heat and power loss, totaly fell on its face when we hit 115 degrees out more-so than a 525 merc, I lost 400rpm and what mid-range hit that I had, 3rd was water pump {raw water} taking forever to draw raw water and eventually failing both pumps, the 4th was trying to sell the piece of ****

How were the drives? The NXT is all about the drives....

Actually the 700's are important to me because of altitude and temp compensation

Interesting on the power loss. I have found that the Imor actually does not lose any power at 100+degrees vs. the Merc. Maybe you had another issue. Did you contact Imor to resolve your problem? At idle I considered it great. Planning was a different sound alltogether though. I found that from ilde to full throttle the powerband to be unreal. It was nearly veritical throughout and also showed this on the dyno sheets.
Just curious, could you have had another problem?
