I'm the original owner of a 1988 Donzi 18 Classic, Testa Rossa edition. I am thinking about selling it and was wondering how rare the 18 Testa Rossa is and what it is worth. It has about 177 hours on it and is in like new condition. I bought it from a dealer in Maine and had it shipped to Washington State. After putting about 50 hours on the 350 Magnum, I pulled the engine and put in a Mercruiser 420 HP 454, Alfa SS outdrive, Kiekhaeffer tabs, Latham hydraulic steering, etc. The engine with Gil exhaust and cam change is conservatively 450 HP now. The boat will run up to 87 MPH on the Nordskog speedometer. I work on boats and all the work done 20 years ago was done professionally with the use of correct Mercruiser parts for the engine conversion. There are 3 short video clips on YouTube of it running and a pass by at 85 MPH while going over small boat wakes. Titles are: "1988 Donzi 18 Classic Testa Rossa at 85 MPH" (1 of 3, 2 of 3, and 3 of 3). Sorry, I can't seem to figure out how to post them here under the video section.
