Choosing an inflatable boat for fishing or recreation is always a search for a balance between mobility, comfort and carrying capacity. riviera It has long established itself as a manufacturer of reliable and affordable boats that are ideal for outboard motors. Unlike simple rowing models, the transom plate options require special attention to bottom design and cylinder stiffness to withstand the vibration and thrust of the engine.
Modern models such as series Compact, 320 or 370They are often equipped with a low-pressure inflatable keel (LDPH) or a floorboard bottom, which drastically changes the driving performance. A properly selected motor will allow you to plane even at full load, ensuring stability on the wave. In this article, we will discuss in detail how to make good choices with power and what to look for in operation.
Owners often wonder if you should overpay for a reinforced transom or if you should limit yourself to a hinged option? The answer depends on whether you plan to walk at speeds above 20 km / h and go out into the open water. For quiet fishing in quiet backwaters, basic versions are enough, but for active trolling or long-distance crossings, you will need more serious hull preparation.
Design features of the Riviera boats for the engine
The basis of any inflatable boat designed to install the engine is a transom plate. riviera It's usually made of laminated plywood, water-resistant paint or laminate, and the rigidity of this element is critical: if the transom is going to play under load, the motor will not be able to push the vessel efficiently, and the vibration will quickly destroy the mounts.
The second important element is the type of bottom. low-pressure (NHPD) provide excellent cross-country and softness, but have limits on maximum engine power due to the shape of the bottom. Pillar variants (aluminum or plywood floor) are tougher, better hold the plane and allow you to put more powerful engines, but require more time to assemble and dry.
Also worth noting is the stringer and inflatable keel attachment system, which in high-quality models, the keel balloon acts as a keel, providing course stability, which is especially important when installing the engine. The absence of a rigid keel can lead to yaw boats at speed, making driving tedious and dangerous.
- 🚤 transom plate: It should be reinforced with overlays and have the correct inclination angle for the daydvut.
- ⚓ Material of cylinders: used reinforced PVC density of at least 750 g / sq.m. for protection against punctures.
- 🔧 Fixtures: The presence of leer rings and handles for carrying facilitates the transportation of a heavy set.
⚠️ Warning: Never install a motor more powerful than the manufacturer's recommended norm per transom without first strengthening the design, this can lead to the detachment of the transom and loss of the engine.
Selection of optimal engine power
The question of boat and engine compatibility is one of the most discussed issues among water-engineers. riviera The best engine is 5-9.8 hp, which is enough to bring one or two people with minimal equipment to the plane, and exceeding power can lead to transom overload and disruption of the centering.
For boats with a length of 340-360 cm, you can already consider engines with a capacity of 9.9-15 hp. Such bundles allow you to feel confidently on the wave and take on board more cargo. However, here comes the rule of compliance: the heavier the boat and cargo, the more powerful the engine is needed, but within reasonable limits, dictated by data-sheet figures.
Electric motors also find their application, especially on water bodies with a ban on internal combustion engines. riviera Traction motors with thrusts from 30 to 55 pounds are suitable, they are silent, do not require registration with GIMS (in most cases), and allow you to fish in places closed to gasoline counterparts.
It is important to consider not only horsepower but also the weight of the engine itself. A heavy four-stroke engine can shift the center of gravity at the stern, which will require moving passengers or cargo closer to the nose for balancing. two-stroke units are lighter, which is often a decisive factor for small PVC boats.
When choosing a motor for a Riviera boat, always leave a power reserve of about 10-15% of the maximum allowable to have a confident plane in headwind or current.
Comparison of popular Riviera models
The range is extensive, and it is easy for a beginner to get confused in acronyms, most often between the compact Compact series models and the more spacious inflatable keel versions, each with its own specific tasks, from solo fishing to family walks.
Models with an M or T index often already have a transom pasted, which makes it easier to install the engine, but increases the weight when assembled. Collapsible transmuter plates are easier to transport, but take time to install. Below is a comparison table of popular modifications.
| Model | Length (cm) | Max power (hp) | Type of bottom | Load capacity (kg) |
|---|---|---|---|---|
| Riviera 290 | 290 | 5-8 | Pilled | 350 |
| Riviera 320 | 320 | 9.9 | NDNDM/Pyol | 450 |
| Riviera 340 | 340 | 15 | NDMA | 550 |
| Riviera 370 | 370 | 18-20 | NDMA | 650 |
Choosing between NDMA And with floorboards, remember this: the inflatable floor gives you a gain in build speed and softness, but loses in stability at high speed. The plywood bottom is tougher and more stable, but the boat is heavier and takes longer to assemble. For rivers with fast flow, a hard bottom is better.
For fishing from a boat with a length of 320-340 cm, the best choice will be a model with NDNDM and a 9.9 hp engine, providing a balance of speed and comfort.
Installation and fastening of the motor
Mounting the engine on a transom is a very careful procedure, and you first need to install the transmutation pads (if they are removable) and attach them with bolts, and then the boat is suspended or placed on a flat surface to try on the motor, and it is important to place the motor in the center of the transmunus.
The fastening is done by means of rods that must fit snugly to the surface of the transom. Between the metal parts of the rods and the PVC cylinder must be a gasket or transumer itself to prevent damage to the material. After fixing, check the tightening of all screws.
The next step is to adjust the lower unit angle, and when you go to plane, you usually put the lower unit in a middle or elevated position, and if the bow is too tilted, you have to reduce the angle, and if you adjust it properly, you reduce fuel consumption and you increase speed.
- 🔩 Fixing: Use additional safety ropes, tying lower unit to the rims on the cylinder.
- 🛢️ Lubricant: Before the first start, check the level of oil in the gearbox and fuel mixture.
- 🌊 Launch: Never start the engine out of water or without water supply to the pump.
⚠️ Attention: When installing the engine, make sure that the anti-cavitation plate is 1-2 cm below the level of the bottom of the boat, otherwise cavitation and engine overheating will occur.
Operation and care of PVC materials
Durability of the boat riviera PVC is resistant to UV and salt water, but afraid of sharp objects and open fire. After every fishing trip, especially in salt water, the boat must be rinsed with fresh water to wash away the salt and dirt.
Storage should be carried out in a dry, cool place, away from the heating appliances. It is recommended to keep the boat in a half-blown state or rolled up in a free roll, avoiding the formation of rigid clamps on the bends. Regular treatment with a special composition for PVC will prolong the life of the material.
Small punctures can be sealed at home using a remix that comes in the supply, the surface is degreased, glue is applied, and a patch is put in the same material, and it is important to let the glue dry the required time specified in the instructions before pumping the boat.
How to dry the boat properly?
The boat cannot be dried in the direct scorching rays of the sun in a completely inflated state, this will lead to a stretch of the seams. It is best to dry in the shade, in a half-blown form, straightening all the folds.
Water safety and GIMS
Operating a motorized boat imposes a safety obligation, and having life jackets for each passenger is not just a formality, it's a necessity, and even experienced swimmers can lose consciousness from hitting the side or balloon in a sharp maneuver.
Registration with GIMS is mandatory for boats weighing more than 200 kg (in running order) or with a motor power of more than 8 kW (about 10.8 hp). For popular bundles of "Riviera 320 + 9.9 hp" registration is often not required if the total weight does not exceed the limit, but the rules can change and they need to be monitored.
Always check the weather forecast before you go out. The inflatable boat has a high sailing speed, and a sudden squall can be a serious test. Keep an anchor with a margin of linen with you, so that if the engine fails, you can anchor yourself and not be demolished to dangerous areas.
Do I need to register a Riviera boat with a 9.9 hp engine?
Registration depends on the total weight of the boat and the engine. If the total weight exceeds 200 kg, registration is mandatory. Riviera boats 320-340 cm with light engines often fit into the limit, but 370 models with heavy engines and batteries may require registration.
What kind of gasoline to pour into the engine for a PVC boat?
two-stroke engines use an AI-92 or AI-95 gasoline blend with a special oil for water engines in a ratio of 1:50 (or according to the instructions for the engine). For 4-strokes, pure gasoline is poured, oil is in the crankcase. Use of old or poor-quality fuel will lead to engine failure.
Can I swim on the Riviera boat in the cold?
PVC material becomes brittle at temperatures below -10°C...-15°C. A hit on ice or a sharp bend can lead to cracks. Exploitation is possible, but requires extreme caution, the use of special frost-resistant lubricants and keeping the boat warm before leaving.
