Okey, thank you for your help!
The funny thing is that some people here in Sweden, when I show them pictures and they look at my prop shaft height they say it looks fine.
That it should be no problem with the drive that high.. Even if I tell them its a non step heavy V-hull.
They say that I should look at my propeller instead and fix it because that could be the problem.. but maybe they dont really know what they talking about..?
So its really confusing

Heres some new numbers:
@4950-5000 rpm - 49-50 mph
@4650 rpm - 53 mph
At 4950-5000 rpm the drive was out a bit, frowing a rooster tail.
At 4650 rpm it was less out.
the slip is at 35% now
Maybe its the right way with lower drive/prop shaft.
Broke the shift cable on the way back home.. couldnt get the neutral or reverse in.. Maybe the shift cable have jumped out of its position in the drive...?

Going to the right direction, and this was with your 26" bravo? If so, try the stock 24" bravo next.

Actual numbers with the 2 spacer, prop shaft height at 2,3 below bottom.
I have one guy that wants to trade his Bravo XR lower for my Sportmaster. The prop shaft height will be at 3,7 below bottom with the standard XR lower.

I tried to trim up a little bit at a time till I got the highest mph numbers > 52,7 mph @4650 rpm I think the gauge did say.
When I trimmed upp more, the speed went down and rpm went up along with the rooster tail at the back...
Thinking of trading my Sportmaster lower in for a Bravo XR lower. Im getting like $830 in between from the guy that wants to trade it. Dont know if its a fair deal..
It will take me to 3,7 below bottom.
