I don’t know, that’s what I’ve read on this website. Appreciatiate you calling me out though. I’m not bull**** I promise you that.

Not trying to bust your chops, Ive heard the same type of comment but the speed additive was when you got above the 90 mph range. I still don't buy it, I've kinda tried all that stuff by default. Probably not apples to apples, but in my boat for instance (28 Nordic) it takes about 17HP per mph. So, an imco lower would be almost like adding 70HP in that case.

Now, a blueprinted lower? Theres some data to suggest a couple MPH with those.

I'm not sure how much speed is increased with a SC lower, it's all hear say. I will say that prop shaft height has made a huge difference with our boat. Taking a 1/2 inch out of the drive increased our top speed 7mph, not's not bull****. If someone would post this info without my testing I would call bull****.
