WSJB 300 Fully Welded Hull: Skip the Shop, Start the Fun!
Tired of browsing and ready to build? The WSJB 300 Fully Welded Hull is your fast track to a custom, high-performance mini jetboat. We handle the complex aluminum fabrication so you can jump straight to fitting the engine and hitting the water.
This 2-person mini jetboat hull is the ideal, professional foundation for an exhilarating build. At 3.4 meters long and 1.5 meters wide, this vessel offers maximum agility and speed in a compact package.
Ready-to-Go, Professionally Built
Stop worrying about welding inconsistencies and tricky plate alignment. Our expert fabricators deliver a flawlessly welded, structurally sound hull, saving you dozens of hours and ensuring a perfect finish.
- Zero Welding Required: Start your build immediately with engine fitting, steering, and accessory installation.
- Engine Bay Ready: The hull and engine bay are perfectly sized and positioned for a Rotax ACE 900 (Sea-Doo Spark) engine, simplifying your drivetrain installation, but larger / stronger engine can be installed if required.
- Superior Stability: Features an aggressive 12-degree deadrise and an integrated trim flap, making this vessel exceptionally stable and agile—virtually impossible to tip over.
Built with Marine-Grade Quality
Your hull is constructed from the same, high-quality aluminum used in commercial vessels:
- 5mm plates are used for the critical hull-plate and chines.
- 3mm plates form the rest of the structure.
- The hull features large, welded stringers for maximum rigidity and strength.
Intake and Transom Configuration
We provide two ready-to-fit options for your jet pump:
- The hull and transom come standard without cut-outs, allowing you to precisely measure and fit your own custom intake assembly.
- Need the easy route? We offer the hull with pre-cut openings designed specifically for any intakes, like our own Sea-Doo Spark jet pump intake. Simply let us know when ordering.
