| Panther 55-0410 Auxiliary Outboard Motor Bracket | Four-stroke motors on mid-size setups | Five vertical positions, extra-wide 2″ mounting board, torsion springs |
| Camoo TSP-1 & TSP-2DP Transom Support Plate Kit | Transom stress distribution for heavy engines | Distributes mounting bolt stress, standard sizes for major brands |
Mojiate Outboard Motor Bracket Auxiliary Stainless Steel
This heavy-duty mounting bracket is designed for 2-stroke motors from 7.5 to 20 HP. It uses marine-grade 304 stainless steel with a 2.5 mm thickness and a reinforced frame for added durability. The base is plastic, which helps reduce weight while maintaining strength. Best for: boaters who need a corrosion-resistant, long-lasting mount for mid-range engines. Limitation: weight capacity is constrained to around 110 lbs (50 kg).
2 Stroke Marine Outboard Motor Support
This bracket is tailored for two-stroke engines in the 7.5–20 HP range, delivering a maximum load around 115 lbs (52 kg). Its reinforced welded aluminum frame and solid plastic mounting board offer durable performance and easier lifting/balancing of the motor. Best for: small to medium boats seeking a robust, lighter-weight aluminum option. Caution: not recommended for four-stroke motors.
Mojiate Heavy Duty Outboard Motor Bracket
Designed for 2-stroke motors 7.5–20 HP with a maximum weight of 52 kg (115 lbs). Features anodized aluminum construction and a solid polypropylene mounting board, with a lift range of about 13.38 inches. Best for: small to medium powerboats and yachts needing a robust, corrosion-resistant solution. Limitation: aluminum components may require periodic inspection for galvanic corrosion in salty environments.
Panther 55-0410 Auxiliary Outboard 4-Stroke Motor Bracket
This anodized aluminum bracket accommodates the heavier torque and weight of modern four-stroke engines with a long or short shaft. It offers five vertical running positions and a 2″-thick, extra-wide mounting board plus stainless steel hardware for heavy-duty operation. Best for: boats needing precise motor positioning across varying loads. Caution: may be bulkier, requiring more deck space.
Camoo TSP-1 & TSP-2DP Transom Support Plate Kit
The two-pack kit includes transom plates for top and lower bolt holes, with 3/8″ thickness aluminum. It helps distribute bolt stress and protect the transom when mounting heavier engines today. Best for: ensuring longevity of the transom under higher torque and vibration. Limitation: requires proper hole alignment to universal mounting patterns.
Buying Guide: Key Purchase Considerations
- Engine type and HP range: Select mounts rated for your engine’s horsepower and shaft length (two-stroke vs four-stroke). Some brackets are optimized for 7.5–20 HP, others for heavier four-stroke loads.
- Material and corrosion resistance: Stainless steel and anodized aluminum resist corrosion in saltwater environments. Consider external coatings and maintenance needs.
- Mounting footprint and weight: Ensure the mounting area on the transom is compatible with the board size and that the weight of the assembly won’t exceed transom capacity.
- Adjustability and lift range: Brackets with multiple positions or adjustable height help achieve optimal engine alignment and balance under varying loads.
- Compatibility with mounting patterns: Transom plates and brackets should align with common bolt hole patterns used by major manufacturers.
- Installation effort: Some kits include mounting plates or quick-release features; check for required tools and included hardware.
- Maintenance considerations: Look for easy-to-clean surfaces and replaceable fasteners to extend life in harsh marine environments.
FAQ
- What mounting board is best for a small two-stroke engine? A: Look for a heavy-duty aluminum or stainless-braced bracket designed for 7.5–20 HP two-stroke engines, such as Mojiate options with reinforced frames and adjustable positions.
- Do transom plates help long-term engine mounting? A: Yes. Transom plates distribute stress from mounting bolts and can prolong transom life when using heavy engines.
- Can these mounts fit different hulls? A: Many mounts use standard bolt patterns, but always verify bolt hole spacing and deck clearance for your specific boat model.
- Are stainless steel mounts better for saltwater use? A: Stainless steel offers excellent corrosion resistance, but ensure proper maintenance to prevent galvanic corrosion when paired with other metals.
- Is adjustable height important? A: Yes. Adjustable height improves engine alignment, reduces vibration, and helps achieve optimal trim for varying loads and water conditions.
- Should I choose an aluminum mount over stainless? A: Aluminum mounts are lighter and resistant to corrosion in freshwater; stainless is stronger and more durable in harsh environments, but heavier and may require more maintenance.
