The SureSeal design allows the vessel operator to replace worn lip seals in the housing with these spare lip seals without uncoupling the shaft from the transmission. If necessary, the worn lip seals may be replaced in the water – no haul-out required.

The spare lip seal carrier is a lightweight, two-piece composite housing which is clamped over the spare lip seals and onto the propeller shaft between the SureSeal and the propeller shaft coupling. They are available in both imperial and metric sizes.

• Spare seal carriers for propeller shafts with diameters up to and including 1 3/4″ contain one spare lip seal in a single housing.
• Spare seal carriers for propeller shafts with diameters from 2″ up to and including 3″ contain two (2) spare lip seals, each in their own housing.
• Spare seal carriers for propeller shaft diameters 3 1/4″ and larger contain two spare lip seals in a single housing.

They are the only lip seals covered under the Tides Marine Warranty.

The outer shell is made of an Aramid fiber composite which is integrally molded to a rubber hinge with a nitrile edge. A 316-stainless steel garter spring is incorporated to distribute loads evenly over the propeller shaft or rudder stock.

When ordering replacement lip seals, note whether you have a SureSeal shaft seal or a StrongSeal shaft seal. Descriptions of each are listed on the Shaft Seals, SureSeal vs StrongSeal Page here.

NOTE: When ordering, please supply the manufacturers part number (located on the face of the lip seal) to make sure you receive the correct replacement lip seal. It is also helpful if you can provide the Tides Marine Serial Number located on your existing part.

Parts Included in this Kit:

• FSA-90M-XXXX-X x 1
• Articulated Hose x 1
• Clamps x 4
• HAT-MM90-02 x 1

The Minimum Distance required from the end of the stern tube to the coupling is 7 1/4 Inches.
Water from Raw Water Feed to SureSeal that delivers a minimum of 1 Gallon per Minute at Engine Idle Speed and increases as you throttle up, at a minimum of 2 psi.

SureSeal Drip Free Self-Aligning Shaft Seal

The SureSeal Shaft Seal is a drip-free, self-aligning propeller shaft seal that is OEM equipment on many well known brands and types of vessels. The SureSeal supports propeller shaft sizes ranging from 1 inch up to 8 inches and from 25 millimeters to 160 millimeters.

With Twin Engine vessels, we recommend the SureSeal model with dual injection fittings so a passive crossover line can be installed between the 2 SureSeal shaft seals. This way, if you are trolling or have a breakdown on one engine, cooling and lubricating water is still being supplied to the SureSeal that is on the idle engine.

If you install a Spare Seal Carrier Kit at the same time you install the SureSeal shaft seal, when the time comes, you will be able to change the Lip Seal in the water. No need to break the coupling or haul the vessel.

The only information needed to purchase a SureSeal shaft seal is your propeller shaft diameter, the OD of your stern tube and that you have verified that there is enough room between the end of the stern tube and the coupling to install the SureSeal.

Distance from the End of the Stern Tube to where the Lip Seal will ride on the shaft, generally between 4 to 7 inches ahead of the stern tube.
Please Note: If the surface of your propeller shaft (between the propeller shaft coupling and the stern tube) is in poor condition (tool marks, rust, or pits) it will be necessary to bring this area of the shaft back to “like new” condition.

If a stuffing box has worn a groove on the propeller shaft surface, it may be necessary to adjust the Tides blue hose that covers the stern tube (or the hose end of the SureSeal) to locate the lip seal ahead of this area.

If your shaft condition is suspect (as described above) and hose adjustments cannot position the lip seal to an unblemished spot on the shaft, (while maintaining a 2 clamp engagement on both ends of the hose), a Face Seal product may be a better choice than the Tides Product
