It ensures full contact between the engine bracket and transom and fits all standard 4-bolt patterns across brands. Best for boaters who want a straightforward, brand-agnostic positive tilt solution. A potential limitation is that installation requires aligning with existing 4-bolt patterns on various engines.
Bob’s Machine 319-200000 Transom Wedge – 5°

Designed for versatile use, this wedge supports both negative and positive trim, making it adaptable to different setups. It helps boats with insufficient transom angle and those experiencing low-speed planning issues. It fits all motors with BIA bolt patterns, offering broad compatibility. Choose this if you want a flexible option that covers multiple trimming scenarios; be mindful that performance may vary with specific hulls and trim configurations.
T-H 5 Degre Positive Tuck Transom Wedge (TW-2-DP)

Manufactured from cast aluminum, this wedge adds 5 degrees of correction to the transom angle, promoting better holeshot and planing. It is built to maintain solid support between the outboard bracket and the transom and fits standard 4-bolt patterns. Best for boaters seeking a durable, straightforward installation with noticeable trim improvement; avoid if your engine mounting does not align with 4-bolt patterns.
T-H Marine Reverse Transom Wedges Pair (TW-3), 5° Positive Tilt

This reverse transom wedge features a 5-degree positive tilt designed to lift the bow and improve efficiency on various outboard setups. Constructed from durable cast aluminum, it resists corrosion and wear. It’s best for users needing a robust, long-term solution with easy installation for standard 4-bolt patterns. Consider potential fit issues with non-standard transom configurations or non-4-bolt mounting.
Mangrove TS-Block Transom Saver Wedge

The TS-Block is designed to brace outboard motors during transport. It fits a range of single ram tilt systems, helping to prevent tilting motion that can stress the tilt/trim unit and transom. It uses a high-density EPDM rubber formula and does not require drilling. Best for trailer-towing scenarios and for protecting the transom and tilt system during transport; note it is a saver wedge rather than a primary trim-angle adjuster.
Buying Guide
What should I consider when choosing a transom wedge?
- Outboard compatibility: Ensure the wedge matches your engine’s bolt pattern (commonly 4-bolt) and mounting layout.
- Angle target: Decide whether you need a 5-degree positive tilt, 5-degree tuck, or a versatile option that supports both trims.
- Material and durability: Cast aluminum wedges offer corrosion resistance and long-term strength for marine use.
- Intended use: If you trailer often, consider a transom saver wedge like the TS-Block to minimize stress on the tilt mechanism and transom.
- Installation requirements: Some wedges are bolt-on with no drilling, while others may require basic alignment to the transom.
FAQs
- Do transom wedges work with all boat brands?
Most 4-bolt pattern wedges fit many brands, but always verify bolt spacing and pattern compatibility before purchasing. - Will a wedge improve my boat’s holeshot?
Yes, a properly chosen wedge can improve bow lift and planning, which contributes to a quicker holeshot, depending on hull and propeller setup. - Is a saver wedge better than a trim wedge?
Saver wedges protect the transom during towing, while trim wedges adjust attitude during operation. Some boats may benefit from both in different contexts. - Can I install a wedge myself?
Yes, many wedges are designed for straightforward, bolt-on installation. Follow manufacturer guides and ensure proper alignment. - What are common signs a wedge is needed?
Poor planing performance, bow-down attitude at acceleration, or inconsistent engine-to-transom contact can indicate a wedge may help.
