Motor Tohatsu 5 hp 2 stroke: current price and market analysis

The search for a reliable and economical outboard motor for a small inflatable boat often leads water-engineers to consider the model. Tohatsu M5BDSThis unit has proven to be one of the lightest in its class, which is a critical parameter when using lightweight PVC smelters. The issue of cost is especially acute, since the purchase budget is often limited, and the desire to save can lead to the purchase of a poor-quality counterpart.

In the current market conditions The price of the Tohatsu engine is 5 hp The two-stroke version of this engine attracts attention for its ease of maintenance and lack of sophisticated electronics, making it an ideal choice for fishermen who value reliability above environmental standards. It is important to understand what the final amount on the price tag is, so as not to overpay for unnecessary options or, conversely, not to buy a “cat in a bag”.

The analysis of the offer shows that price variations can be significant even within the same region, due to the presence or absence of a warranty, completeness (the presence of a screw, tank, oil) and the status of the seller. In this article, we will discuss in detail the pricing policy, technical features of the two-stroke “five” from the Japanese brand and help you determine the best purchase option, based on real data and experience.

Value factors in the current season

Cost of outboard motor Tohatsu M5BDS 2S (two-stroke) is not static, it depends on the market conditions. The main driver of the price is the dollar and euro, as the equipment is imported. However, there are internal factors that affect the total amount you see on the check, and understanding these mechanisms allows you to choose the most profitable time to purchase.

The first important aspect is the sales channel, and the official dealers offer the equipment with full factory warranty and service support, which inevitably increases the number of products sold. retailWhile private ads or grey suppliers may offer lower numbers, the risks of buying in such places are many times greater, and the absence of a formal warranty can result in costly repairs in the event of a factory defect.

The second factor is the configuration. The basic version may cost less, but for full operation you will need to buy a separate fuel tank, hose and possibly a screw with a different step if the standard does not fit your tasks. Two-stroke 5 hp engines often don’t have a built-in tank in base supply for some years, requiring a separate purchase. This should be taken into account when planning the budget.

Seasonality also influences price. In spring, in anticipation of the navigation, demand increases, and dealers rarely discount. In autumn, when the season ends, you can catch good offers for selling off leftovers. M5BDS It can be difficult.

Technical features of two-stroke modification

Two-stroke engine Tohatsu 5bhp It's different from four-strokes, and it uses a mixture of gasoline and oil that burns down in one turn of the crankshaft, and it delivers high power specifications per kilogram of weight, and for many users, weight is the decisive argument, because it's a questionable pleasure to drag a heavy motor along the shore.

The key feature is the lubrication system. Unlike four-strokes, where the oil is in the crankcase, here it burns with the fuel. This requires constant monitoring of the mixing ratio. Usually, a 1:50 ratio is recommended when using quality synthetic oils for two-stroke engines. piston-blower Or, conversely, to coking candles and silencers.

The engine is cooled by off-board water through the pump. The system is simple and reliable enough, but requires regular checks of the control jet. If the water jet has disappeared during operation, operation must be immediately stopped to avoid overheating. The two-stroke design also implies higher noise and vibration levels compared to the four-stroke counterparts, which is worth considering when choosing.

The carburetor is an important element. M5BDS It uses a reliable float carburetor that is well-established in our environment, less sensitive to fuel quality than injection systems, but requires periodic cleaning and adjustment, and simple design allows for minor repairs even in the field with a minimum set of tools.

Price comparison: official dealer vs private

When looking for a motor Tohatsu 5bhp The buyer often faces a dilemma: overpay for the guarantee or take a risk by buying from a private buyer. Let's take a look at the pros and cons of each option so you can weigh the pros and cons.

Buying from a dealer provides legal protection, you get a warranty card that is valid in authorized service centers throughout the country, if the manufacturer breaks, you will be replaced by a unit or unit for free, and dealers often conduct pre-sales preparation (break-in, check of knots), which excludes factory defects at an early stage.

⚠️ Warning: When buying from hand, be sure to check for the original warranty book with the seller's stamp and date of sale. Without these documents, the warranty does not apply even if the engine is new.

Private ads (Avito, Yula, forums) offer prices lower by 15-30%. However, there are risks. The engine may be stored incorrectly (for example, with residues of fuel in the carburetor), which leads to corrosion and acidification. There is also the possibility of buying equipment that has been in the water (drowned), which was restored only externally.

Another nuance is the configuration: private individuals often sell engines without documents, which makes it impossible to register with the GIMS (if it is required for your boat) or put on a warranty. Absence of SPM (passport self-propelled car) or a check can become a problem when traveling abroad or just when communicating with inspectors on the water.

Operation and maintenance costs

Buying an engine is just the beginning of the expense. Tohatsu 5bhp It requires regular investment to maintain performance, and the main cost is the fuel mixture, and the fuel consumption of this model is about 1.5-2 liters per hour at full speed, which is an excellent indicator of efficiency.

You also need to consider the cost of quality two-stroke oil. You can not save on oil, because engine repair will cost many times more. Regular maintenance includes replacement of spark plugs, lubrication of the rotation and tilt knots, and check of the lower unit lubricant.

The table below shows a rough comparison of the annual maintenance costs of a two-stroke and four-stroke engine of similar power under heavy operation (50 motor hours per season).

Item of expenditure	two-stroke Tohatsu 5 hp	four-stroke analogue of 5 hp
Oil (for the season)	~2-3 liters (mixed)	~0.5 litres (replacement)
Fuel consumption (AI-95)	~80-90 litres	~70-80 litres
Replacement of oil in gearbox	Every year.	Every year.
Complexity of service	Low.	Medium/High

As you can see from the table, a two-stroke engine requires more oil, but it's consumed along with the fuel. A four-stroke engine is more fuel efficient, but more difficult and expensive to repair. Resource of two-stroke engine With proper operation and high-quality mixture can reach several thousand motor hours.

What to look for when choosing a screw

The standard screw, coming in complete with Tohatsu M5BDSIt has certain pitch and diameter parameters, and it's designed to maximize the engine's speed on medium load, but if you're planning to use a full-load boat or if you're going to be on your own, you may need to change the propeller.

If the engine does not reach full speed (the howler does not sound at maximum), then the screw is too heavy (a big step), in this case the engine is running with overload, which leads to overheating and increased fuel consumption. If the engine spins more than the permissible revs (goes into spat), the screw is too light, and you do not use all the power.

How do you pick up the screw?

To select the screw, you need to take measurements with a tachometer. Normal working turns for Tohatsu 5 hp are in the range of 4500-5500 rpm If less - change to a screw with less pitch, if more - with more.

The material of the screw also matters. Aluminum screws are cheaper and lighter, but when hit by a rock or a snag, they often break, saving a lower unit. Steel screws are stronger, but their installation on low-power motors is rarely economically justified. For clay water bodies with floating grass, increased pitch screws are better suited to avoid winding.

Therefore, experiment with screws should be careful, constantly monitoring the tachometer readings.

Conservation and storage tips

Your durability Tohatsu 5bhp It depends on how you store it in the off-season, and two-stroke engines are particularly sensitive to the oxidation of the internal cavities if you leave the old fuel in them, and gasoline has the ability to decompose, forming a resinous plaque that clogs the jelly of the carburetor.

Before long-term storage, you need to extract all the fuel from the carburetor float chamber, so you can shut off the fuel hose tap and let the engine run on the remaining gasoline until it stops, a simple but effective procedure that will save you from starting problems next spring.

⚠️ Warning: Never keep a full fuel tank engine inside the room, and the gasoline vapors are explosive and the mixture can dissipate, causing clean oil or water to enter the engine.

It is also recommended to lubricate the internal cavities of the cylinder, twist the candle, splash some engine oil inside and slowly scrolle the starter several times (or pull the starter with your hand if the engine does not start), which will create a protective film on the cylinder mirror and the piston, preventing corrosion.

Keeping the engine upright, in a dry room, covered with dust cloth, and checking the state of the lower unit lubricant before each season is also mandatory. If the lubricant has acquired a milky shade, then water has entered the gearbox, and the replacement of the osteoils is required.

Frequently Asked Questions (FAQ)

What is the maximum speed of a boat with a Tohatsu 5 hp engine?

The speed depends on the type of boat, its loading and the pitch of the propeller. For a single inflatable boat with one passenger, the speed can reach 20-25 km / h. When fully loaded, the speed will decrease to 12-15 km / h. For glides, this power may not be enough for heavy boats.

Do I need to register the 5 hp engine in GIMS?

According to the legislation of the Russian Federation, registration is subject to small vessels with an engine of more than 8 kW (about 10.88 hp). A motor with a capacity of 5 hp (3.68 kW) is not subject to registration if the total weight of the equipped vessel does not exceed 200 kg.

Can I refuel a two-stroke Tohatsu with 92nd gasoline?

The manufacturer recommends that gasoline with an octane number of at least 95. Use of 92 gasoline is possible, but can lead to detonation and overheating of the engine, especially under load. This reduces the life of the engine. It is better not to save on fuel.

Where is the serial number on the Tohatsu engine?

The serial number is stamped on a plate that is located on the lower unit (motor foot), usually on the right or left side, closer to the transom fastening, and the number is duplicated in the warranty card and technical data sheet.
