We just picked up our first Donzi a few weeks ago and are having a blast with it!!
It's a '90 22 Classic w/ OMC King Cobra 454 (cone clutch). The boat is actually in very nice shape, it has about 30 hrs on it since an overall deck off restoration plus rebuild on the 454. The gelcoat is flawless. It will do 68 mph @ 5,200 rpm with a 23" prop, one on board, half tank of fuel. The speedo is accurate to iPhone GPS. I understand the King Cobra drive is good for about 600 HP - lbs/ ft and am considering swapping in a 540 - 572 ci "600-ish" hp pump gas engine as a winter project. I figure that might get it up to 80 mph @ 5,600 rpm with a 26" prop. Does that sound about right? Will it be ok w/o hydraulic steering??
Here is short video of a test with my son after sorting some ethanol issues. Yep, It works!!
