YIYIBYUS 2.3HP 52CC Outboard Motor
Reference: Power is 1.7 kW (2.3 HP) with a 52cc two-stroke engine and non-contact electronic ignition. Idle speed sits around 2800–3200 rpm; operating speed is 4500–8500 rpm. The unit uses a fuel mix ratio of 25:1 and a compact 0.22-gallon fuel tank. Shaft length is 27.55 inches. Built with aluminum and PP for corrosion resistance and durability. This model emphasizes portability and ease of use for small craft.
Best for: Very light inflatables, small dinghies, and casual fishing boats where ultra-low weight is priority and users want simple maintenance.
Why selected: It balances compact size with adequate power for lightweight vessels, offering reliable ignition and efficient operation in calm waters. The aluminum construction helps resist corrosion in marine environments.
Caution: As a 2-stroke, fuel mixing is required (gas-oil ratio 25:1), and prolonged high-load use may increase emissions and require more frequent maintenance than modern four-stroke designs.
JooWing 2.3 HP 52cc Outboard Motor
Reference: A 2.3 HP, 52cc air-cooled two-stroke engine with a 0.22-gallon external fuel tank and a three-blade propeller. Features include an ergonomic non-slip rubber handle and a solid mounting bracket for secure attachment. The unit supports 40–70 minutes of continuous operation per full tank, depending on load and speed. The engine uses CDI ignition for reliable starting.
Best for: Kayaks, small inflatable boats, and portable fishing setups where quick refueling and light handling are important.
Why selected: Its portable, compact design and quick refueling capability make it a practical choice for short trips and occasional use. The air-cooled system reduces weight and simplifies maintenance.
Caution: Air-cooled engines may require careful heat management in hot conditions and during sustained high-rpm operation to avoid overheating.
Gosangom 3.5HP Short Shaft Outboard Motor
Reference: A 3.5 HP two-stroke outboard with water cooling and a compact short shaft (about 36 x 14.17 x 5.9 inches) weighing around 21.6 lbs. The propeller is a 6.7″ three-blade design, optimized for reducing water resistance and delivering smoother power. It uses a lightweight aluminum alloy body with corrosion-resistant coatings for freshwater and saltwater use.
Best for: Small rubber boats, inflatable craft, and kayaks needing more thrust than a 2.3 HP unit but still light enough for easy handling.
Why selected: Higher power output provides better acceleration and speed on modest hulls while maintaining portability. The combination of light weight and efficient prop design improves performance on smaller craft.
Caution: Short shaft versions may not fit deeper hulls; verify shaft length against boat transom height before purchase.
PERFERATE 6HP 2-Stroke Outboard Motor
Reference: A robust 6 HP, 102cc heavy-duty two-stroke engine with water cooling and CDI control. Tiller control motor features straightforward throttle and steering operations with a continuously variable transmission for speed adjustments. The unit emphasizes low noise, with a larger top-mounted muffler designed to reduce engine noise around 80 decibels during operation.
Best for: Inflatable boats and dinghies that need stronger propulsion for planing or heavier loads while maintaining manageable handling for a hobbyist or weekend boater.
Why selected: It provides significantly more power than smaller units, enabling better performance in choppier water or with heavier gear. CDI ignition and water cooling enhance reliability for longer sessions.
Caution: Increased power comes with higher fuel consumption and heavier weight, which may affect portage and mount stability on smaller craft.
eaizybuk 2.3HP Air-Cooled 52cc Outboard
Reference: This 2.3 HP, 52cc two-stroke engine uses CDI ignition and an air-cooled design for heat management. It features an ergonomic rubber handle for grip and a rigid mounting bracket to secure the engine to the boat. A 0.22-gallon external fuel tank supports 40–70 minutes of operation depending on load and speed.
Best for: Lightweight inflatables, dinghies, and kayaks where quick setup and easy transport are priorities.
Why selected: The unit’s air cooling makes it simpler to maintain, and the compact footprint is ideal for travelers or small crew boats. CDI ignition improves starting reliability.
Caution: Air cooling may require attentive ventilation in enclosed or hot environments to prevent overheating during long runs.
Buying Guide
What boat size and weight should you target with a 2 hp outboard? Use power-to-weight guidelines and consider hull type. For inflatables and dinghies, lighter engines (2.3 HP) keep handling responsive. For slightly larger craft, 3.5–6 HP can improve planing and accelerate load-bearing vessels without dramatically increasing weight.
What shaft length is right? Short shafts fit most small inflatables and dinghies. If your transom height is higher, consider a medium or long shaft to ensure proper prop clearance and avoid cavitation.
What about cooling and maintenance? Air-cooled engines are lighter and simpler but may overheat under heavy use. Water-cooled designs provide better temperature management for longer runs and tougher conditions, yet add weight.
What fuel considerations matter? Two-stroke engines mix fuel and oil, typically at a 25:1 ratio, and offer higher power-to-weight but require more maintenance. Four-stroke equivalents are cleaner and more fuel-efficient but heavier and pricier.
Ease of mounting and controls: Look for a tilting or tiller-style control, depending on your boat design. CDI ignition provides reliable starts, especially in cooler conditions or after storage.
FAQ
- Do I need a 2-stroke or 4-stroke motor for a small inflatable? A 2-stroke generally offers higher power-to-weight and quicker acceleration, but requires fuel-oil mixing and more maintenance. A 4-stroke is cleaner and typically more fuel-efficient, but heavier and more expensive.
- What shaft length should I choose? For most small inflatables and dinghies, a short shaft is sufficient. If your transom is higher, opt for a long or medium shaft to prevent cavitation and ensure prop clearance.
- How important is cooling method? Water cooling provides better long-duration performance and durability in hotter conditions, especially for higher workloads. Air cooling saves weight but can overheat on sustained runs.
- Can these motors be used in saltwater? Many models are designed for freshwater and saltwater use; confirm corrosion resistance and anodes if you’ll operate in saltwater. Rinse and dry after use to extend life.
- Is CDI ignition necessary? CDI ignition improves starting reliability, especially in cooler weather and after storage. It is common in small to mid-size two-stroke outboards.
- How do I match horsepower to boat load? For lightweight craft with a couple of passengers, 2–3.5 HP is often adequate. Heavier gear or larger inflatables benefit from 6 HP or more for better thrust and planing ability.
