Trdzi Stern Drive Trailering Clips for Mercury Alpha, Bravo & Blackhawk — PVC Support Clip, Multiple Sizes (fits #817019A2)

Trdzi Stern Drive Trim Cylinder Trailering Clips are durable PVC support clips designed to secure Mercury Alpha, Bravo and Blackhawk trim cylinders during transport, compatible with part #817019A2.

When trailering your boat, an unsecured trim cylinder can shift, strain hydraulic lines, or damage the drive. These Trdzi trailer clips act as a simple, low-cost safeguard that holds the drive trim cylinder steady and reduces movement without permanent modification to the outboard. Built from corrosion-resistant PVC, they replace or supplement OEM supports for several Mercury models and come in sizes matched to common Alpha, Bravo and Blackhawk trim-cylinder layouts.

How do these clips keep my stern drive stable on the road?

The clips cradle the trim cylinder and lock it in place so the drive can’t flop or vibrate excessively while towing. By limiting motion they protect the trim mechanism, anodes, seals and hydraulic fittings from knocks and fatigue during transit.

• Firm PVC grip resists slipping and cushions the drive.
• Shapes sized to match Mercury Alpha, Bravo and Blackhawk cylinders.
• Prevents excessive travel that can stress hoses and pins.

Which Mercury models and part numbers does this fit?

These trailering clips are designed for Mercury Alpha I, Bravo I & II and Blackhawk stern drives, and are compatible with the OEM reference #817019A2. Trdzi supplies multiple DIY size options so you can select the correct length for your specific drive and anode configuration.

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

How hard is installation and what tools are required?

Installation is straightforward and designed for DIYers: the clip slips into place to cradle the trim cylinder and requires minimal adjustment. No specialized tools or permanent modifications are needed, so you can fit or remove the support quickly between outings.

• Tool-free or basic hand tools only for fast mounting.
• Slides into position to provide immediate support.
• Removable for maintenance, winterizing or storage.

What materials and longevity can I expect from Trdzi trailering clips?

Manufactured from high-quality, marine-grade PVC, these clips resist rust and corrosion that commonly affect metal supports. The plastic construction absorbs shocks and won’t pit like aluminum or steel, giving long-lasting protection when used as intended.

• Corrosion-resistant PVC construction for saltwater use.
• Durable under repeated install/removal cycles.
• Designed to resist UV and moisture exposure typical of trailering.

Who is this for? Boat owners who tow Mercury Alpha, Bravo or Blackhawk stern drives and want a simple, affordable way to protect the trim cylinder during transport will benefit most. Ideal for weekend boaters, marina operators and anyone who prefers a removable, corrosion-resistant support rather than heavy metal brackets. If you need a direct replacement for part #817019A2 or want a practical trailering safeguard, these Trdzi clips offer a quick installation and long-term protection for common Mercury drive setups.
