T-H Marine 5 Degree Positive Wedge
Best for boaters needing immediate dial-in for engine trim. This 5-degree negative tuck adjusts the transom angle to improve holeshot, planing, and running attitude. Cast aluminum construction provides solid support between the engine bracket and transom. It fits standard 4-bolt patterns for straightforward installation. Caution: Verify your transom thickness and bolt pattern to ensure compatibility with your outboard model.
Bob’s Machine 319-200000 Transom Wedge – 5°
Best for versatile trim needs, as it can be used with either positive or negative trim. Helpful for boats with insufficient transom angle or low-speed planing issues. Compatible with all motors using BIA bolt patterns. Limitation: Some installations may require carter or bracket space beyond the standard pattern.
5 Degree Positive Tuck Wedge For All Brands
Best for universal fit across brands, offering full contact between engine bracket and transom. The 5-degree tilt improves bow-up stability and helps with even load distribution. Suitable for both port and starboard installations. Caution: Check that your transom and engine bracket have the required clearance for a full 5-degree chamfer.
Asaki TW-2-DP Transom Wedges
Best for a direct OEM-style replacement that matches original equipment dimensions. Specifically engineered to increase 5 degrees of tuck (negative tilt) to improve hole shot and reduce bow rise. Offers precise fit against standard 4-bolt transom configurations. Limitation: The data notes a “TW2DP” reference; confirm this matches your assembly before purchase.
ProPart Transom Wedge 5 Degree
Best for OEM-grade aftermarket compatibility, with a stated aim to match or exceed OEM specifications. It provides a 5-degree positive tuck for a bow-up stance and full contact with the transom. Use this when you want a factory-like fit across multiple brands. Caution: Double-check the bolt pattern and spacer requirements for your specific engine model.
SupplyMount 319-200000-NOPC Wedge
Best for straightforward aftermarket replacement, designed to be a reliable fit for common 5-degree wedges that align with Bob’s Machine wedge patterns. Durable construction supports long-term performance. Limitation: Verify part number compatibility with your specific transom and engine mounting layout to avoid misfit.
NorthBoat Transom Saver Wedge Set
Best as a wedge-support kit for trailering scenarios, combining a 5″ transom saver with 2x 4″ hydraulic steering locks. Intended to absorb road shock before reaching the motor, helping protect the transom during transport. Caution: Confirm that your hydraulic trim/tilt system is compatible with the included locks and saver blocks.
Buying Guide
What to consider when choosing a 5-degree transom wedge:
- Engine and transom compatibility: Confirm bolt pattern, transom thickness, and bracket clearance before purchase.
- Intended outcome: Positive tuck (bow-up) versus negative tuck (bow-down) and how that affects planing and handling.
- Brand and fit: OEM-style replacements can simplify installation; universal options require careful measurement.
- Durability: Look for marine-grade materials like cast aluminum or corrosion-resistant alloys.
- Installation effort: Some wedges require only bolt-on installation, others may need brackets or spacers.
