41-43 to me sounds low, considering that mine as delivered gave me 47, with similar weight. Could my hull be that much better? My 50 was achieved after upgrading to an Enertia (most awesome prop I ever used).
In the waters I ply, waves are often an issue. I typically run at ~30 mph, so having the extra 20 is of no concern to me. Based on my performance curves, 30 is the optimum cruise throttle anyway (best mpg) so for me it works out well. Do you want to be able to blow everybody's doors off, or go out to have family fun?
Which is better? I dunno. In one case tried and true cables and rods and a big block. In the other, servos and all the extra parts associated with a turbo. Tried and true vs. modern tech. You be the judge.
We once had a 'ski with an SC and it turned out to be more extra maintenance that I liked. So, we switched back to an NA. Much better fuel economy, no maintenance and it has been bulletproof for 6 seasons now.
