A strong choice for a sailboat pairs a shaft suited to the transom with enough power for the boat’s needs, and the LSYSGSB 7hp Long Shaft is the clearest match here because its listing explicitly includes sailboats and gives a stern-height range. The other six options are 18HP two-stroke engines, a substantially different power class with 24-liter or 6.34-gallon fuel capacities listed for several models. That difference matters: a larger engine is not automatically a better fit for a sailboat.
This roundup compares the listed power, fuel capacity, materials, weight information, and included equipment while noting where listings leave important compatibility details unclear. Confirm shaft length, transom height, mounting fit, and your boat maker’s engine limits before choosing.
The LSYSGSB 7hp Long Shaft is the strongest match for most sailboat shoppers in this lineup because its product data explicitly lists sailboats and gives a stern-height range of 17.71–21.65 inches. It is a 4-stroke model with a 1.4-liter fuel capacity, unlike the six 18HP two-stroke options. Choose an 18HP alternative only if that power class suits your boat and its approved engine limits; the listings do not establish that every model fits every sailboat.

1. LSYSGSB 7hp Long Shaft
- Fuel Capacity: 1.4 liters
- Material: Alloy Steel
Best for: Sailboat backup motor buyer.
Why it ranks #1: Its listing explicitly names sailboats and a 17.71–21.65-inch stern-height range; the 7HP four-stroke is a distinct alternative to the six 18HP two-strokes.
A stated stern-height range of 17.71–21.65 inches makes LSYSGSB’s 7-hp long-shaft outboard particularly specific for sailboat buyers matching a transom. Its four-stroke, 196cc engine produces up to 5.1kW, with water cooling and a 6.3-inch three-blade propeller.
The stated stern-height range lets a buyer compare the motor with a boat’s transom before planning installation. Its 7-hp four-stroke engine and 6.3-inch three-blade propeller are specified for operation, with the streamlined propeller shape described as reducing water resistance. Throttle control handles acceleration and steering, and step-less speed regulation enables gradual speed adjustment. The 1.4-liter fuel capacity is a practical boundary for trips, while the listing names sailboats among compatible vessel types.

#3 · Most Complete Kit
3. YUASDUU 18HP Outboard
- Fuel Capacity: 24 liters
- Material: Aluminum
Best for: Water-start-ready boat operator.
Why it ranks #3: Its listed package includes a fuel tank, oil pipe, tool kit, and accessories; the maker also specifies water-starting and break-in precautions.
A required water start is the key operating distinction of YUASDUU’s 18-hp long-shaft outboard: the manufacturer says not to start it ashore. Its 246cc two-stroke engine, 4,500–5,500 rpm range, water cooling, and tiller control define the rest of its listed setup.
The aluminum-alloy body has a painted finish and is described as resistant to corrosion, wear, heat, impact, and deformation, supporting use in water. A muffler is specified to reduce operating noise, while water cooling addresses engine heat management. The included fuel tank, oil pipe, tool kit, and accessories provide items for setup; operation also requires evenly mixed gasoline and two-stroke oil. The roughly 10-hour running-in period calls for avoiding high throttle during that initial use.
- 18-hp, 246cc two-stroke engine rated at 4,500–5,500 rpm
- Water-cooling system and tiller control
- Muffler specified to reduce operating noise
- Includes fuel tank, oil pipe, and tool kit

#4 · High Load Capacity
4. Cbhfmljd 18HP Outboard
- Fuel Capacity: 24 liters
- Material: Aluminum, Plastic
- Weight: 28 kg
Best for: Higher-load fishing boat operator.
Why it ranks #4: The listing states a maximum load capacity of 2,204 pounds and a 24-liter fuel capacity, but does not identify sailboats as a recommended use.
A stated maximum load capacity of 2,204 pounds distinguishes Cbhfmljd’s 18-hp long-shaft outboard, giving operators a clear load figure to consider when matching a motor to a heavily equipped fishing boat. Its 246cc, two-stroke engine operates at 4,500–5,500 rpm and uses water cooling.
The aluminum-alloy construction is described as corrosion-resistant, rust-resistant, and resistant to bending, which addresses durability concerns in the listed fishing-boat use. A 24-liter fuel capacity provides the stated reserve, while water cooling supports heat management during operation. The 2,204-pound maximum load figure helps buyers assess capacity, with the manufacturer noting that heavier loads reduce speed. The 28kg weight and manual operation are worth factoring into installation and handling plans.
- 18-hp, 246cc two-stroke engine rated at 4,500–5,500 rpm
- Stated maximum load capacity of 2,204 pounds
- 24-liter fuel capacity
- Aluminum-alloy construction described as corrosion- and rust-resistant
- The manufacturer states that speed decreases as the carried load increases.

5. awolsrgiop 18HP Outboard
- Fuel Capacity: 6.34 gallons
- Material: Aluminum, Plastic
- Weight: 28 kg
Best for: Hands-on tiller-control operator.
Why it ranks #5: It lists a 6.34-gallon fuel capacity and a 20-inch non-slip handle, but the listed recommendations focus on fishing boats and fresh water.
A 20-inch non-slip handle gives awolsrgiop’s 18-hp long-shaft outboard a specific tiller-control feature: a long grip for steering and speed adjustment by hand. Its 246cc two-stroke engine runs at 4,500–5,500 rpm, and the listing also states a 2,204-pound maximum load capacity.
The manual-start setup uses a starter rope and a speed switch on the handle, keeping start and speed control within the operator’s hands-on workflow. The 20-inch non-slip tiller handle provides a defined grip surface, while flexible steering and precise speed control are listed operating features. Its water-cooled 18-hp engine and 6.34-gallon tank pair power with fuel capacity for fishing-boat or kayak use; the stated maximum load is 2,204 pounds, with speed falling as load increases.
- 20-inch non-slip tiller handle
- Manual start using a starter rope and handle speed switch
- 18-hp, 246cc two-stroke engine rated at 4,500–5,500 rpm
- 6.34-gallon fuel capacity and stated 2,204-pound maximum load
- Starting requires pulling the starter rope by hand.
Skip it if you prefer an 18-hp motor with a stated 24-liter tank; Cbhfmljd’s 2 Stroke 18HP lists that capacity.
Choose this awolsrgiop when you want manual tiller operation, a long non-slip grip, and the listed 18-hp output for a fishing boat or kayak. Its starter-rope procedure and load-related speed reduction are important operating boundaries.

6. BJTDLLX 18HP Outboard
- Fuel Capacity: 6.34 gallons
- Material: Aluminum, Plastic
- Weight: 28 kg
Best for: Long-range fishing boat operator.
Why it ranks #6: The 18HP two-stroke lists a 6.34-gallon tank and 28-kilogram weight, but its recommended uses are fishing boats and fresh water rather than sailboats.
A 6.34-gallon fuel tank is the clearest differentiator on BJTDLLX’s 18-hp long-shaft outboard, giving fishing-boat operators a larger stated fuel reserve for short or long trips. Its 246cc, two-stroke engine runs at 4,500–5,500 rpm, while water cooling helps manage heat during extended use.
The 24-liter tank, also listed as 6.34 gallons, supports longer stretches between refueling, a practical benefit for trips where stopping is inconvenient. Its water-cooling system and multiple cooling holes address heat dissipation during prolonged operation, while CDI ignition and a two-cylinder 246cc engine supply the specified powertrain. Manual operation and 28kg weight are relevant handling considerations when planning installation or moving the motor; the stated recommended use is fishing boats and fresh water.
- 18-hp, 246cc two-stroke engine rated at 4,500–5,500 rpm
- 6.34-gallon fuel capacity
- Water-cooling system and multiple cooling holes
- Forward, neutral, and reverse gear selection
- Manual operation requires the operator to handle controls directly.
Skip it if you want a four-stroke 7-hp motor for a sailboat stern height of 17.71–21.65 inches; LSYSGSB’s 4-stroke 7hp model lists that range.
For fishing-boat owners seeking an 18-hp long-shaft motor with a 6.34-gallon tank and water cooling, this BJTDLLX is a relevant option. Its listed recommendations are fishing boats and fresh water, so check those operating conditions against your intended use.

View on AmazonWhy it ranks #7: Its 18HP two-stroke lists a 24-liter fuel capacity and fishing or aquaculture uses; the provided description does not specifically establish sailboat compatibility.
A stated hull-size guideline sets the clearest fit boundary for the Hangkai 18-hp long-shaft motor: the listing describes suitability for small boats under 4.9 feet wide and 19.7 inches long. Its 246cc two-stroke engine, water cooling, and 6.34-gallon tank shape the operating package.
The 18-hp engine is listed at 4,500–5,500 rpm, and the manufacturer gives a maximum load of 2,204 pounds, noting that heavier loads reduce speed. A 24-liter tank, also described as 6.34 gallons, provides fuel capacity for outings, while water cooling is part of the engine setup. The listing names fishing boats, kayaks, fishery, and aquaculture as uses and includes a fuel tank, oil pipe, manual, and service tools for setup and upkeep.

Why the stated shaft label is not enough
A long-shaft label alone does not confirm that an outboard will fit a particular sailboat transom. The LSYSGSB 7hp Long Shaft is the only listing here that provides a stern-height range, 17.71–21.65 inches, but that figure still needs to be checked against the boat’s measured transom and the motor’s actual shaft dimension. The other listings call their engines long shaft without giving a corresponding shaft measurement in the supplied data.
This creates a practical compatibility trap: choosing by the label or horsepower alone could leave the propeller at an unsuitable depth. Check the manufacturer’s shaft measurement and your boat’s mounting requirements before ordering, and confirm that the engine’s weight and horsepower are allowed for your vessel.
The product data does not establish those details for every model, so treat them as questions to verify rather than assumptions.
Two-stroke fuel handling and startup cautions
The 18HP two-stroke listings require buyers to account for fuel preparation and water-based startup procedures rather than treating them like a ready-to-run four-stroke. The YUASDUU 18HP Outboard specifically says to mix gasoline with two-stroke oil evenly, start the motor in water rather than on shore, and keep throttle low during an approximately 10-hour running-in period. Those are meaningful operational requirements for a sailboat owner who may want an auxiliary motor ready for occasional use.
The LSYSGSB 7hp Long Shaft is described as a four-stroke, so it is a different engine type, but the supplied data does not detail its fuel procedure. Confirm the manual’s requirements for whichever model you choose.
For any candidate, plan how you will store and handle fuel aboard, and do not assume the included fuel tank or accessories remove the need to follow the maker’s instructions.
How to Choose a Sailboat Long-Shaft Outboard
Horsepower and boat fit
Look for an engine power rating that falls within your sailboat maker’s approved limits, rather than assuming more horsepower is better. The LSYSGSB 7hp Long Shaft is the only 7HP model and is explicitly listed for sailboats; the remaining six choices are 18HP two-strokes. That is a substantial difference in power class, but the product data does not state what size or displacement of sailboat each 18HP engine suits.
The 7HP option favours buyers seeking the explicitly listed sailboat use and lower stated horsepower. An 18HP model may suit a buyer whose boat is rated for that power and who wants one of the listed higher-output engines.
Verify your vessel’s limits and intended use before selecting either end of the range.
Fuel capacity and engine type
Check both the stated tank capacity and the engine type, while remembering that capacity alone does not establish cruising range. The LSYSGSB 7hp Long Shaft is a four-stroke with a 1.4-liter fuel capacity. The 18HP two-strokes list either 24 liters or 6.34 gallons; those are roughly equivalent stated capacities, though the listings do not provide comparable consumption figures.
A buyer who prioritizes a larger listed tank may prefer one of the 18HP models, while a buyer seeking the only four-stroke option may prefer the LSYSGSB. Do not infer runtime or distance from tank size: operating conditions, load, speed, and engine consumption are not supplied.
Confirm fuel requirements in the manual, especially for a two-stroke that requires the specified fuel-and-oil mixture.
Weight, materials, and supplied equipment
Compare listed weight and included equipment with your boat’s mounting and handling needs, but note that several listings omit one or both details. The LSYSGSB 7hp Long Shaft lists alloy steel and a tool kit, funnel, and English manual; its stated fuel capacity is 1.4 liters. BJTDLLX 18HP Outboard and two other listings specify a weight of 28 kilograms, while NAZEAOB 18HP Outboard lists 93.7 pounds.
Several 18HP models list aluminum or aluminum alloy, but the LSYSGSB listing says alloy steel. Buyers who need a lighter motor for frequent handling should seek a confirmed installed weight before purchase, since the data is inconsistent or absent for some choices.
Buyers who want a supplied kit can compare the components listed for YUASDUU and LSYSGSB against their own needs.
Which Long-Shaft Outboard Fits My Sailboat?
For a sailboat buyer, start with the LSYSGSB 7hp Long Shaft: it is the only listing that explicitly names sailboats and gives a stern-height range of 17.71–21.65 inches. If your boat’s approved power limit permits 18HP and you want that class, consider NAZEAOB 18HP Outboard for its stated F-N-R gears, or YUASDUU 18HP Outboard if the included fuel tank, oil pipe, and tool kit matter. Cbhfmljd 18HP Outboard lists a 2,204-pound maximum load capacity, but that is not proof of sailboat fit.
Before buying any option, confirm the motor’s actual shaft measurement, transom compatibility, boat horsepower limit, and operating instructions. The listings do not supply enough detail to confirm those points across all seven models.
Related Buying Guides
Frequently Asked Questions
How do I measure my sailboat transom to confirm the required shaft length?
Measure the vertical distance from the top of the transom where the motor mounts to the bottom of the hull directly beneath it. Compare that measurement with the motor’s actual shaft measurement and the manufacturer’s stated range. Confirm fit with the motor maker or boat documentation; the listings do not provide this detail for every model.
How much horsepower can my sailboat safely and legally use?
Use only the horsepower permitted by your sailboat’s capacity plate, manual, or applicable local requirements. Do not assume that an outboard’s advertised horsepower is suitable for your boat. If the limit or documentation is unclear, ask the boat manufacturer or a qualified marine professional before selecting an engine.
What fuel and oil mixture does a two-stroke outboard require?
Follow the specific motor’s operating manual for its fuel type, oil specification, and mixing ratio; do not guess or use a ratio from another engine. The listings identify six options as two-stroke but do not state their required mixture. Confirm the instructions before fueling or operating the motor.
Does a long-shaft label confirm the motor will fit my sailboat?
No. A long-shaft title alone does not establish the motor’s actual shaft measurement or compatibility with your transom. Check the boat’s required shaft length against the manufacturer’s motor specifications, and verify mounting and operating requirements.
The LSYSGSB listing alone explicitly states a stern-height range of 17.71–21.65 inches.
What should I verify before choosing an 18HP option?
First confirm that your sailboat’s approved engine limit permits 18HP, then verify shaft length and transom compatibility. Compare the listed features that matter to you: NAZEAOB states F-N-R gears, while YUASDUU lists a fuel tank, oil pipe, and tool kit. Those details do not establish fit for every boat.
Final Words
For most sailboat shoppers in this lineup, start with the LSYSGSB 7hp Long Shaft: it explicitly names sailboats and lists a stern-height range of 17.71–21.65 inches. Its 4-stroke design also distinguishes it from the six 18HP two-stroke options. Consider an 18HP model only when your boat’s approved limit allows it.
Before deciding, confirm actual shaft measurement, transom compatibility, and operating instructions; the listings do not verify fit across all seven motors.
