Inflatable rowboat Intex Seahawk 2 The 68351 is a popular budget option for a one- or two-passenger ride, originally designed for oar rides, and is often upgraded by anglers and leisure enthusiasts. engine on the Seahawk 2 boat How to do this without damaging the inflatable tubes?
The hull design does not include a rigid transom out of the box, which creates certain limitations when choosing a power plant. However, the market offers many solutions to equip this boat with an engine. loading capacity and capacity The two are closely related: a motor that is too powerful can become dangerous, and a motor that is too weak can become inefficient.
In this article, we will discuss the technical nuances of installing internal combustion engines and electric motors, consider the necessary accessories and discuss safety issues. The maximum power allowance for Seahawk 2 is limited to 3 hp.What are the ways to securely fix the motor on the soft side?
Technical specifications of the boat Intex Seahawk 2
Before you pick up the engine, you need to study the data-sheet figures of the boat. Model 68351 is 2.36 meters long and 1.17 meters wide. The design is made of durable vinyl, but the bottom is soft, inflatable, which critically affects the hydrodynamics and resistance to loads from the screw.
The standard includes two inflatable seats and paddles, but for motorization the key parameter is loading capacityThis includes the weight of passengers, equipment, fuel and the engine itself, and if you plan to use a 10-12 kg gasoline engine, the payload will decrease, which is something you need to consider when planning your fishing trip.

- 📏 Width: 117 cm
- ⚖️ Load capacity: 200 kg
- 👥 Capacity: 2 people
It's important to note that the lack of a hard bottom (in the basic version) does not allow you to reach high speeds even with a powerful motor. horsepower In this case, the model does not make practical sense.
Compatibility with gasoline engines
Installation of a gasoline engine is the most common, but also the most difficult, option of modernization. PVC boat manufacturers usually specify the maximum power that the transom board and cylinders can withstand. Seahawk 2 This limit is 3 hp (about 2.2 kW).
Using more powerful units, such as 5 hp, will lead to excessive load on the aft part, which can lead to leaks in the places of gluing of the transom board or, in the worst case, deformation of inflatable tubes under the influence of persistent screw force. In addition, the weight of a four-stroke engine at 5 hp can be excessive for such a light boat.
Lightweight two-stroke models from proven brands are the best choice: they are compact, easy to maintain and have a low weight, which is critical for maintaining a buoyancy margin.

⚠️ Attention: Never use motors above 3 hp on an Intex Seahawk 2 without strengthening the transom, which can cause the seams to break and the vessel to sink rapidly at depth.
Electric motors: an alternative to gasoline
For a quiet and eco-friendly walk is ideal. electric motorUnlike ICE, electricians don't require a mixture of gasoline and oil, they don't smoke, and they work almost silently, and this is especially important for catching careful fish that are frightened by the noise of the engine.
Electric motor thrust is measured in pounds (lbs). Seahawk 2 A 30-40 lbs (about 13-18 kg) thrust model is enough; more powerful units will be superfluous and require a heavy battery, which will upset the boat's balance; the main advantage is the ability to install the motor on the nose or on the roomer control from either side.
The key element here is batteryFor a 30-40 lbs engine, the best choice would be a 45-60 Ah lead-acid battery or a lighter Li-Iron-Phosphate (LiFePO4) analogue. Lithium batteries are much lighter, saving precious kilograms of payload capacity.
Use LiFePO4 batteries instead of lead batteries, which weigh 2-3 times less at the same capacity as small boats like the Seahawk 2.
Necessary accessories for installation
Because it's complete with a boat. Intex Seahawk 2 There are two main types of attachment: a hinged transom, which is fixed to cylinders with slings, and a glued transmolant, mounted on the bottom, which is better for temporary use.
The hinged transom should have soft but strong stops so as not to damage the PVC fabric. Often used models with height adjustment, which allows you to adjust the screw-deepeningYou will also need a cat anchor to anchor the boat while fishing, as the sailing speed of the inflatable board is high.
☑️ Shopping list for motorization
Don't forget to be safe. Even if you're planning to go for a ride, you're safe. lifejackets It is also recommended to have a remix and a pump running on a battery or car lighter.
Instructions for engine installation
The process of installing the engine requires care and consistency of actions. Incorrect fixation of the transom can lead to its displacement under load, which can lead to the engine falling into water or damage to the cylinder by a screw.
First, inflate the boat to working pressure (usually 0.25 atm for cylinders and 0.35 atm for the keel, if any). Set the hinged transom straight in the center of the stern. Secure it with belts worn through special handles or covering cylinders. Make sure there are no sharp corners between the hard board and the soft fabric.
Sequence of installation:1. Inflate the boat to working pressure.
Set the transom in the centre of the feed.
3. Lock the belts, avoiding distortions.
4. Hang the motor without starting it.
5. Check the tightening of all attachments.
After the engine is attached, check the inclination angle of the lower unit. Ideally, the screw should go into the water completely, but the capsule should not touch the surface when moving. Seahawk 2 A small different is characteristic on the stern when landing two people, so the engine is often put slightly higher than on rigid housings.
The main principle of installation is rigid fixation of the transom without distortion, any shift in the axis of the engine will lead to the boat's drifting to the side and increased fuel consumption.
Comparison of engine options
To make a final decision, it is worth comparing the main specifications of the available solutions: gasoline engines give freedom of movement and independence from charging, but require preparation of the mixture and maintenance. Electricity is easier to operate, but limited in time.
Below is a table to help you make choices based on your priorities.
| Parameter | Gasoline 2-3 hp. | Electric motor 30-40 lbs | Osla (state) |
|---|---|---|---|
| Weight of kit | 10-13 kg + fuel | 7-9 kg + ABC 10-15 kg | 0.5 kg |
| Speed (1 person) | up to 12-15 km/h | up to 5-7 km/h | 4 km/h |
| Power reserve. | 50 km | 10-20 km (depends on the battery) | Depends on your strength. |
| Noise. | Highly | Minimum | Missing. |
If you prioritize speed and long-distance crossings, gasoline is the only option, and if you're fishing in the "deaf" places where silence is important, or if you're cruising with children, you'd better use electric.
Safety and operating rules
Operation of an inflatable boat with an engine imposes increased requirements for caution. inflatable tubes Beware of sharp objects on the shore, snags in the water and sparks from the exhaust pipe of the engine.
Always check the pressure in the cylinders before going out and after an hour of operation. In the sun, the air inside warms and expands, which can lead to overvoltage of the seams. If necessary, pour excess air through the valves.
⚠️ Attention: Don't leave the boat with the engine installed in the sun unattended. The pressure in the cylinders can rise to critical values, and the engine itself can overheat.
What to do if a balloon is pierced on the water?
If a puncture occurs, don't panic. The Seahawk 2 has several independent compartments. If one cylinder is broken, the other one will keep the boat afloat. Keep your paddles gently or use an electric motor (if not damaged) to the shore. The petrol engine is better to shut down to avoid fire or propeller damage.
Following these simple rules will allow you to enjoy fishing and vacation for years to come, turning a simple inflatable boat into a reliable vehicle.
FAQ: Frequently asked questions
Can I put a 5 hp engine on the Seahawk 2?
Technically, it can be fixed, but it's dangerous. The design of the transom board and cylinders is not designed for the thrust and weight of such a motor. The risk of seam rupture and loss of buoyancy is very high. It is recommended to limit 3 hp.
Which battery is better for an electric motor?
A typical car or boat battery 55-60 Ah is suitable for starters, however, for regular use it is better to invest in an AGM or LiFePO4 traction battery that withstands a deep discharge and weighs less.
Do I need to register a boat with an engine?
According to the legislation of the Russian Federation, the registration in GIMS subject to boats weighing more than 200 kg (in running order) OR with engine power more than 8 kW (about 10.8 hp). Seahawk 2 lighter than 200 kg, and the engines on it are weaker than 10 hp, registration is usually not required, but the rules may change, watch for updates.
How to keep a boat in winter?
The boat needs to be thoroughly washed, dried and deflated, stored in a straightened form or in a free twist at room temperature, and do not leave it in an unheated garage or on the balcony, where temperature changes and exposure to ultraviolet light are possible.
