1998 Donzi 23 Sport Deck

1998 Donzi 23 Sport Deck — Fully Repowered, Turn-Key Ready in Tampa Bay A rare opportunity to own a classic Donzi Sport Deck that has already received the expensive mechanical upgrades most buyers end up tackling themselves. This 23-foot fiberglass deck boat blends Donzi's legendary performance heritage with the open, family-friendly layout of a true deck boat — and it's ready to launch. The centerpiece of this build is a freshly installed 5.7L Vortec V8 paired with a Holley Sniper Electronic Fuel Injection system and Hyper Spark ignition. The result is instant hot and cold starts, smoother throttle response, improved fuel economy, and the elimination of carburetor headaches — all professionally installed. A new SEI 116 Alpha One Gen II outdrive with stainless steel propeller rounds out the drivetrain, giving buyers a fully refreshed mechanical package with only 100 hours on the engine. The deck layout is spacious and social, with captain and passenger bucket seats up front, a large rear sun pad, walk-through windshield, ample storage throughout, and a bimini top for shade. A large swim platform and boarding ladder make water entries easy for the whole family. A tandem axle trailer is included — just hook up and go. The hull presents well for its age with a great shine, clean upholstery, and a comfortable cockpit. Clean title in hand.
