What Are Inboard Jet Boats?
In the simplest terms, an inboard jet boat houses its engine and jet drive system within the hull—typically beneath a deck or engine cover—rather than attaching an outboard motor to the transom. Water is drawn through an intake grate under the hull, forced through an impeller, and expelled at high velocity from a nozzle at the rear. This thrust propels the boat forward and allows for agile turning and steering control.
Unlike traditional inboard propeller systems, the jet drive in these boats avoids external shafts and propellers. Instead, thrust relies on directed water flow, dramatically improving shallow water access while minimizing the chances of tangling in weeds or striking underwater obstacles. For boaters wanting power, safety, and the freedom to explore remote, shallow waterways, inboard jet propulsion is a game-changer.
Inboard Jet Boat Advantages
You might be wondering—why opt for an inboard jet system over outboard jets or traditional propeller-driven vessels? Here are the highlights:
1. Shallow Water Freedom
With no propeller hanging below the boat, you can traverse water just inches deep, ideal for fishing flats, coastal marshes, or rocky river sections. This also cuts down on the risk of damaging external hardware when venturing into unknown waters.
2. Enhanced Maneuverability
Inboard jet boats excel at quick turns, spins, and side-to-side movements thanks to the directed thrust of the jet nozzle. This agility is a boon for both recreational boaters seeking fun and professionals requiring precision docking or rescue operations.
3. Improved Safety
Removing an exposed propeller significantly reduces hazards to swimmers, divers, and marine life. Inboard jet setups are also advantageous when operating near floating debris, wildlife habitats, or shallow reef systems where a propeller could cause damage or entanglement.
4. Centralized Weight Distribution
Inboard engines position weight low and near the center of the hull. This can enhance stability, reduce bow rise upon acceleration, and free up the transom area for swim platforms, fishing decks, or transom seating.
5. Quiet Operation & Sleek Aesthetics
Containing the engine within the hull helps minimize noise. At the same time, the streamlined exterior often appears more modern and elegant—especially when paired with Novelli’s Italian-inspired designs.

How Inboard Jet Propulsion Works
While the broad concept of jet-driven thrust is straightforward—drawing water in and pushing it out—understanding each component clarifies how these systems achieve power and maneuverability:
1. Intake Grate
Located on the underside of the hull, the intake grate filters large debris and ensures a smooth water flow into the pump. Specific designs can reduce cavitation and maintain consistent pressure even at high speeds.
2. Impeller & Pump Housing
The impeller is the heart of the system, spinning at thousands of RPM to accelerate incoming water. Housing materials, such as stainless steel, resist wear and corrosion. Pitch and diameter are tuned for optimal thrust in various conditions (e.g., shallow rivers vs. open bays).
3. Nozzle & Steering Deflector
After compression in the pump, water exits through a nozzle. Small shifts in nozzle angle—controlled by the helm—direct thrust, allowing precise steering. Additional reverse gates or deflectors let you slow down, back up, or spin on a dime.
4. Inboard Engine Placement
Nestling the engine within the hull maximizes deck space, lowers the center of gravity, and improves aesthetics. It also simplifies servicing in certain aspects since the motor is accessible under a hatch, though routine maintenance differs from outboard setups.
Fuel Efficiency & Speed Potential
Modern inboard jet boats often rival or exceed outboard counterparts in both acceleration and top-end speed. The exact numbers depend on hull geometry, engine horsepower, and load. Here’s a sample table with hypothetical Novelli inboard jet models:
| Model | Length (ft) | HP Range | Top Speed (mph) | Draft (inches) | Fuel Burn (gph at Cruise) |
|---|---|---|---|---|---|
| Novelli Inboard 20R | 20 | 200–250 | 40–50 | 8–10 | 6–8 |
| Novelli Inboard 22X | 22 | 250–300 | 50–60 | 10–12 | 8–10 |
| Novelli Inboard 24 Pro | 24 | 300–350 | 55–65 | 12–14 | 10–12 |
Notice how even with moderate drafts, these boats can achieve respectable speeds and maintain manageable fuel burn. Lightweight aluminum construction, hydrodynamic hull shaping, and efficient jet drive designs all contribute to balanced performance.
