Genuine factory original equipment Tides Marine Brand SureSeal heavy-duty dripless self-aligning propeller shaft seal replacement component assembly (Model / MPN: Lip Seal 3250 | Serial Number: 197008). This premium water-lubricated propulsion component safeguards your vessel's running gear and inboard engine systems by maintaining exact shaft centering while dampening operational drivetrain vibrations. Sourced as an official spare part bundle previously utilized on a Bertram 57 luxury sportfish yacht, this universal marine assembly includes the primary heavy-duty Tides Marine fitting clamps and essential components originally allocated from a full professional installation kit. Sourced from highly durable aramid fiber composite outer shells and securely bonded with a specially formulated nitrile rubber matrix, this water-lubricated lip seal ensures exceptionally uniform, low-friction support. Its advanced internal 316 stainless steel garter spring promotes a continuous, cool-running fluid boundary layer against the shaft, protecting high-strength 3-1/4" propeller shafts from extreme rotational friction, dangerous scoring, or localized heat distortion under continuous heavy-duty maritime propulsion stress.

• Key Features: Advanced nitrile rubber hinge profile for optimized shaft sealing, rigid aramid composite outer carrier shell for high-stability positioning, premium 316 stainless steel garter spring for uniform tension, and heavy-duty marine-grade Tides Marine fitting clamps.
• Technical Specs: Brand: Tides Marine | Base Kit Compatibility: Universal SureSeal / StrongSeal 3250 Series | Serial Number / Kit Origin: 197008 | Prior Application: Bertram 57 Yacht | Shaft Diameter (ID): 3-1/4 Inches (3.250") | Seal Type: LUP Profile Nitrile Lip Seal | Clamp Type: Heavy-Duty Marine T-Bolt/Gear Clamps.
• Condition Notes: This item is a high-quality spare / part-out component bundle in clean, pre-owned operational condition. The composite seal frame and rubber seal lips are physically flawless with zero edge distortion, material tearing, dry rot, or degradation. The included fitting clamps are fully functional with clean threads and zero structural compromises.
• Installation Notes: Prior to seating, carefully clean and check the target propeller shaft section for keyways, nicks, or surface corrosion that could nick the nitrile element during installation. Utilize the proper Tides Marine red hat installation tool if available to slide the lip seal safely into place without turning the spring out of its seat. Align the carrier unit securely on the shaft, tighten the heavy-duty fitting clamps evenly to factory torque specs to eliminate slippage, and cross-verify that your raw water-injection cooling lines maintain clear fluid delivery before operational spin-up.
