Thanks for your interest in this matter!
Yes Google translate is a very good thing isn't it!
zul8tr don't pay to much attention to how the boat rides in the video, I think the speed is only somewhere around 25knots and I was slowing down when I passed the camera. I only included it so you could get a good view of the boat.
The Penta engine in the video is still in my workshop for surgery, it had a severe case of overheating, right now the boat is powered by OMC.
Lets answer some questions:
Setup:
Engine, OMC 56ci 70hp from -92 with trim and tilt, completely stock.
Gear ratio 2.42
WOT rpm between 6300 and 6600
Prop Unknown brand over the hub cleaver 14"x24"
Prop shaft height is 2"-2,5" above bottom. did not find any good picture, sorry!
Top speed is so far 47knots with very little positive trim, (trimmed out from prop shaft parallel to the bottom)
Video of the gear case:
It is quite hard to see the water surface since the lake was like a mirror that day but one can see a shadow just by the leading edge of the gear case.

Lack of power and slightly overweight, sure just like me
I was told that when the hull was built it only weighed 75kg, that was before any of the reinforcement was added (transom, knees, stringers and such) but it was built around -83 so I guess no one really remembers...
I think the hull it self only weighs around 150kg is that heavy?
FastJeff57, about the porpoise, yes, maby the wedges are there to control some longitudinal instability? (speculation from my side)
FrenchPhil In what kind of cats are the steps /wedges still being used? do you have any pictures??
The fact that someone removed the aft portion of the strakes feels like he (most likely a guy, right?) was trying to create more bow lift.
Got myself a new prop for the cat today, a Winrace 14x25" slightly modified by previous owner, lets hope I get to test it before the winter arrives!
