How is the model number of a Honda outboard engine read?
Although every model name begins with “BF,” these two letters are absent from the engine.
The frame’s serial number is stamped into a piece of metal on or close to the stern bracket.
This could also be called a vehicle identification number or a product identification number (VIN).
When did Honda begin producing 4-stroke outboard motors?
First Honda four-stroke outboard motor released in 1964. 1967 saw the debut of the first Honda outboard in America. Customers could choose from a full range of four-stroke Honda models for the first time in 1985. 1990 The IMTEC Innovation Award goes to our BF45.
The Birth of BLAST
A market dominated by 2-stroke engines welcomed Honda’s first outboard engine in 1960.
Although 2-stroke engines are lightweight, have a simple design, and have the advantage of having a high output from a small displacement, 4-stroke engines have better environmental performance and fuel efficiency.
Honda has constantly created eco-friendly 4-stroke outboard engines since its inventor wanted to avoid contaminating the water we ride on.
The objective was to create a 4-stroke engine with acceleration comparable to a 2-stroke while preserving fuel efficiency and environmental performance in order to experience Honda’s distinctive delight of sailing. The solution was BLAST, a special ignition timing and air/fuel ratio system developed by Honda and originally installed on the BF90 in 2006. It is now a standard feature on the BF40-BF250 models*.
BLAST Mechanism and Advantages
The boat’s bow will be elevated (bow up) if there is insufficient power (torque) when accelerating from a stop, making the ride uncomfortable and preventing the boat from planing, which is the most fuel-efficient state.
2-stroke engines accelerate more quickly from a stop than 4-stroke engines because they are lighter and have more power (torque). With a 4-stroke engine, BLAST sought to achieve the same acceleration.
By regulating the air-fuel ratio and spark-advance control, BLAST increases torque for full-throttle acceleration while deciding ignition timing close to knocking restrictions.
BLAST improves acceleration from a stop and hastens the boat’s transition to the fuel-efficient planing mode.
In a 4-stroke outboard engine, BLAST achieves both the pleasure of sailing and greater fuel economy and environmental performance.
How are the serial numbers on Honda engines read?
Look for a model number sticker on the engine to determine the model number. Model numbers for Honda engines always begin with the letter “G,” such as “G100,” “GX610,” or “GXV160.” The base engine model is this one. For the majority of your demands, the engine model and serial number should be sufficient.
When was my boat motor made?
Looking at a paper could be all it takes to determine the year your outboard motor was constructed. For certain motors, the hints are on the motor and are awaiting your use of a key word to solve them. Because neither the model number nor the serial number will provide you any information, you must ask the dealer for at least one if you want to know more than a general time period during which that particular model of motor was created.
If you reside in a state that mandates registration, check the registration certificate the state provided, or the title if you call Utah, Texas, Ohio, South Carolina, Oklahoma, or Missouri home. Both the registration and the title clearly state the model year or the date of manufacturing. This may be one of only two options available to owners of Honda outboard motors to locate the information without calling the Honda dealer.
Look for the details the dealer included about your motor in the operator’s manual for your motor. You must employ a different technique if you don’t have the motor operator’s manual that was packaged with your motor when it was brand-new.
Go to the motor and look for an embossed, metalized tag or plate with the manufacturer’s name prominently stamped at its top on the motor’s swivel bracket. The model year, or the year the motor was created, is also displayed on this manufacturer’s tag, with the exception of Honda motors.
Pull the motor’s top cowling away. This information is engraved on the top center of the engine block of some well-known outboard motor models, although it may also be on a tag that is often located on the right side of the engine block.
If you have an Evinrude or Johnson outboard, check the model number. The 10-letter word “introduces” provided the final two letters of the model number. Up until the letter “E,” which equals nine, each letter equals a different number: the first letter is “1,” the second, “2,” the third, etc. The numbers are the last two numbers of the motor’s year of construction, and the final letter of the word, “S,” stands for “0.” In 2009, a model with the number XXX-XX-XXX-XYX-X SE was created since “S” stands for “0” and “E” for “9.
Tips
- Ask the closest dealer who carries the outboard motor brand you own if none of these options are available to you. Many outboard-parts websites offer a “lookup capability,” but their main objective is to sell components rather than provide information.
Can you use a boat motor’s serial number to find it?
To determine the year your engine was made based on the serial number or model number, choose your boat motor manufacturer from the list above. It will be easier for you to order a manual and parts if you know the year of your engine.
On a boat motor, where is the serial number located?
We’ll need as much information as possible if we need to repair or replace the motor on your boat. It may be simpler to replace your motor with the appropriate parts if you know the make, model, and serial number. Contrast this with the brand, model, and year of your boat.
You’ll see a plate on the side of your motor. You can find the make, model, and serial number here. If it’s an outboard motor, the serial number is the only thing you’ll need.
The information is the same on each model plate, although the layout may change. The model and serial numbers are typically labeled, but if they are not, ask the repairer if you are unclear or get assistance from a dealer.
- A Parsun’s plate can be found on the bracket’s left assembly or the upper portion of the bracket swivel. The serial number has the designation SN.
- The second half of the number on the second line is the serial number for Suzuki.
- Serial numbers for Mercury are typically labeled.
- Honda: The model name typically begins with BF and is followed by the letters on the motor’s rear, such as BF50. The serial number, also known as the product identification number, has the format “BXXX-XXXXXXX.”
- Evinrude – An Evinrude’s transom or mounting bracket is where the serial number is found. The serial number has a label. The model number is especially significant because it provides information about the motor’s type, year, and horsepower.
- The serial number for Yamaha is on the far right of the second line, while the model code is the top number.
How do you gauge a Honda outboard’s shaft length?
The versatility of an outboard engine is one of its main advantages. With the right mounting, almost any type of boat can be propelled by an outboard motor. You will see outboards hanging on the sterns of anything from little canoes to large cruising sailboats, in addition to motorboats built for large outboards. A tiny auxiliary motor is commonly installed on single-engine boats for emergency use.
The shaft length of an outboard motor is one of the most important decisions you can make, regardless of the size of the boat you are operating. Since every boat is unique, there are several various standard lengths produced by the motor manufacturers. Looking at what you have and pulling out the measuring tape will help you determine the correct size. But how would you quantify it?
Measure the distance between the bottom of the mounting bracket, which sits on the transom, and the top of the cavitation plate, which is the horizontal surface of the lower unit just above the propeller, to determine the length of your outboard motor shaft.
There is an illustration that demonstrates where to take the measurements in the article further on. I’ll also go over the distinction between short and long shafts and how they differ depending on the kind of boat.

Honda or Yamaha outboard motors are better?
Four-stroke engines are cleaner, more streamlined, and more effective than two-stroke engines, which are slightly lighter and simpler. Because of this, recreational boaters should consider four-stroke engines.
Despite the fact that both Yamaha and Honda produce four-stroke engines, the Honda outboard is only available in this configuration.
If you want choices, Yamaha might be the better choice. However, if four-stroke engines are more your style, you could like that Honda or Yamaha.
Both the Yamaha and the Honda outboards are four-stroke engines, although they come in a variety of horsepowers.
Yamaha often provides engines with a little bit more horsepower than Honda.
Thus, both the Honda and Yamaha outboard have rather powerful engines, with the Yamaha having slightly greater power.
However, while choosing an engine, power is not the only thing to take into account. Additionally, acceleration is crucial.
Although it is difficult to tell unless under load, the Honda outboard’s acceleration is a touch slower than the Yamaha’s. However, the change is largely insignificant in this case.
