Trdzi Stern Drive Trailering Clips for Mercury Alpha, Bravo & Blackhawk — PVC Trim Cylinder Supports (Size Options)

Trdzi stern drive trim cylinder trailering clips are rugged PVC motor-support replacements designed to secure Mercury Alpha, Bravo and Blackhawk outboard drives during trailering.

When transporting an outboard-powered boat, uncontrolled movement of the stern drive can damage the trim cylinder, anode or transom. These trailering clips are molded replacement supports that fit multiple Mercury drive models (including parts compatible with #817019A2) and keep the trim assembly locked in place, limiting stress and abrasion while you tow.

How do these trailering clips protect my stern drive during transport?

They cradle the trim cylinder and hold the drive at a stable angle so the unit cannot flop or vibrate against the jackplate, transom or other hardware. The clips replace worn or missing supports that would otherwise permit movement and surface contact.

• Wraps the trim cylinder to damp vibration and prevent metal-on-metal contact
• Stops drive rotation or sag that causes seal or anode wear
• Reduces chance of impact damage on bumps or sharp turns

Which Mercury models and sizes do these clips fit?

The set covers several commonly used configurations for Mercury Alpha, Bravo and Blackhawk drives, including variants with or without trim cylinder anodes. Each model size is provided so you can match the correct clip to your specific drive.

• Alpha I Gen. II without trim cylinder anode – 10-1/4 inch (260 mm)
• Alpha I Gen. II with trim cylinder anode – 9-1/2 inch (242 mm)
• Bravo I, II & III with trim cylinder anode – 9-3/4 inch (248 mm)
• Blackhawk trim cylinder support – 8-1/2 inch (216 mm)

What are these clips made of and how long will they last?

Manufactured from high-quality PVC plastic, the clips resist rust and corrosion that commonly affects metal supports. PVC stands up well to saltwater exposure and road grime, giving reliable service as a lightweight, low-maintenance option.

• PVC construction resists corrosion and electrochemical damage
• Lightweight design won’t add significant trailer load
• Durable under UV and wet conditions with routine inspection

How easy is installation and what tools are required?

These trailering clips are designed for straightforward, tool-light installation so you can secure the drive quickly before every trip. Most installations require only hand positioning and common fasteners; the clips are sized to slip into place and support the trim cylinder immediately.

• No special tools required for basic fitting and fastening
• Quick swap replaces worn factory supports in minutes
• Fits standard mounting points on compatible Mercury drives

Who this is for: Boaters who tow Mercury Alpha, Bravo or Blackhawk stern drives and want a durable, corrosion-resistant replacement support for the trim cylinder. Ideal for owners replacing worn factory clips, fleet operators who need dependable trailering hardware, and DIYers who value an easy-fit, size-specific solution compatible with part #817019A2.
