Donzi 21 Hornet, repowered
Guessing some of you will enjoy these pics.
Apparently my old engine broke last year, i tought only the headers cracked. But it was more. Decided to switch it up a little bit
Rerigged the boat myself, 2 full weekends and it was done, electrical, fuel lines, engine assembly etc, my wife was not happy with how much time i spent in the shop those 2 weekends, LOL.
496ho with whipple!
Second run (still adjusting fuelpressure, getting to know the hull at these speeds etc) i have done 74.3 knots, that is 85.5 mph. After 70 knots, it starts to chinewalk badly, so I need some seat-time to get to know the hull, but MAN does it get up and go.. now its a real hotrod! The acceleration is mind-blowing!
Bravo1 xr -2 sportmaster and a Bravo1 30P prop, for now.

However. Its running pretty rich, so its gonna make a little less than that. But ballpark 180-200hp more
