SMC YCN5654BX 1 HP Stainless Steel Boat Lift Motor

The SMC YCN5654BX is a 1 HP, TEFC stainless steel motor designed for direct mounting on boat hoists. It uses a 56C frame and offers dual-voltage wiring (115/230V) with a 1725 RPM specification, making it suitable for standard waterfront hoist systems. Best for owners replacing a worn 1 HP unit in direct-drive hoists where a durable, rust-resistant shell matters. Limitation: Direct-wiring access and mounting must match the 56C frame for proper fit.
EMZ 1.5 HP Boat Lift Motor

The EMZ 1.5 HP motor is built for direct-drive hoists with a stainless-steel body, 56C C-Face mounting, and dual voltage operation (115/230V) at 1725 RPM. This model is better for waterfront setups requiring a higher lifting capacity without a larger frame. Choose this if you have a mid-size boat hoist and want robust performance with outdoor durability. Caution: Verify the exact hoist fitment and voltage compatibility before purchase.
EMZ 3/4 HP Boat Lift Motor

The EMZ 3/4 HP motor is UL Listed and CSA Approved for direct-drive hoists, featuring a stainless steel shell and TENV enclosure. It operates on 115/230V and 1725 RPM within a 56 frame, offering a reliable option for docks that demand compliant electrical components and steady performance. Best for replacement in older, direct-drive systems where corrosion resistance and safety certifications matter. Limitation: Confirm mounting compatibility and hoist model alignment prior to ordering.
Leeson 6439191262 Boat Hoist Motor

The Leeson 6439191262 is a 1 HP, 115/208-230V, 56C frame motor with a C-face mounting, designed for TENV operation in dusty or damp environments. It delivers 1,800 RPM and is suited for direct-drive hoists that operate in challenging waterfront conditions. Best for users who need a rugged, enclosed motor with straightforward wiring. Caution: Check compatibility with your hoist’s voltage and mounting style before purchase.
Leeson 6439191251 Boat Hoist Motor

The Leeson 6439191251 is a 0.75 HP, 115/208-230V motor with a 56C frame and rigid C mounting. It is designed for direct-drive hoists and TENV operation, providing a compact, efficient option for smaller boats or lighter lifting tasks. Best for budget-conscious replacements that still require reliable performance. Limitation: Lower horsepower may limit lift capacity on larger vessels.
Buying Guide
What hoist motor horsepower do I need?
Match horsepower to boat weight and hoist load. Higher horsepower supports faster lift and heavier craft, but may require more robust wiring and controllers. For smaller boats, 0.75–1 HP is often adequate; for larger or heavier loads, 1.5 HP is a safer choice.
Which voltage and frame size should I choose?
Most direct-drive hoists use 115/230V with a 56C frame. Ensure the motor’s voltage matches your power supply and that the mounting flange matches your hoist. A TEFC or TENV enclosure improves outdoor durability in marine environments.
What about corrosion resistance?
Stainless steel housings or fully enclosed designs help resist salt air and water intrusion. Look for TEFC/TENV enclosures and NEMA-rated protection when your hoist operates outdoors near seawater.
Direct-drive compatibility and mounting
Confirm that the motor’s mounting interface (56C frame, C-face) aligns with your current hoist. Incompatible mounting can require adapters or new hardware, increasing cost and downtime.
Safety and certifications
UL-listed and CSA-approved motors provide warranty-worthy baseline safety. For waterfront equipment, these certifications support compliance with local electrical codes and rental or marina operations.
Maintenance considerations
Choose motors designed for marine use with low dust and moisture ingress. Totally enclosed designs reduce debris exposure, simplifying upkeep and extending motor life.
What if I’m unsure about compatibility?
Consult your hoist’s manual or manufacturer for a recommended motor list. If available, bring the hoist’s frame and voltage details to a supplier to verify fit and mounting.
Summary of buying considerations
- Direct-drive suitability: essential for most boat hoists
- Frame and mounting: confirm 56C/C-face compatibility
- Protection rating: TEFC/TENV for outdoor use
- Voltage: ensure 115/230V compatibility with your system
- Certification: UL CSA preferred
FAQ
- What is a 56C frame motor?
- Can I mix brands for replacement motors?
- What enclosure is best for marine environments?
- Is UL listed necessary?
- How do I verify motor voltage on my current hoist?
- What maintenance should I perform annually?
A 56C frame is a common NEMA standard size for electric motors, ensuring compatibility with many direct-drive hoists and mounting flanges.
Yes, as long as mounting, frame size, voltage, and shaft dimensions match your hoist. Verify compatibility before purchasing.
Totally enclosed non-ventilated (TENV) or totally enclosed fan-cooled (TEFC) housings resist dust, moisture, and salt exposure.
UL listing provides safety assurances and can aid in code compliance for residential and commercial docks.
Check the hoist’s wiring diagram or nameplate for voltage rating. If unsure, consult a licensed electrician before replacement.
Inspect wiring, mounting bolts, and enclosure seals; clean any debris; check for corrosion; and verify that the motor spins freely without abnormal noise.
