The PSS Shaft Seal, manufactured for 25 years, uses the well-known system of mechanical seal in order to assure complete water tightness between the propeller shaft and the boat, unlike other brand which uses either a lip seal or a packing gland.
Because of its choice of material, the PSS Shaft Seal can operate in all kind of environment, including salty/sandy waters. Also unlike other type of seals there is no contact, therefore no wear, between the sealing surface and the shaft.
All these qualities make the PSS Shaft Seal the most common brand of Shaft Seals found on the pleasure boat industry today.
Less known is the fact that the PSS Shaft Seals are also very common on all type of work boats (Small ferries, crew boats, fishing boats, coast guards, tugs etc…) as these seals are manufactured for shafts up to 200mm. One huge advantage of these seals on a commercial boat is the lack of maintenance required added to the fact that these seal do not wear the shaft down.
The PSS is approved by RINA, VERITAS, and ABS.

Bronze dripless shaft seal with nitrile seal element. Available in sizes 1" to 3". Chatfield Blue Water seals are Germanischer Lloyd approved.
Chatfield Marine has developed a propeller shaft flexible seal unit designed to be retrofitted to existing stern tube assemblies or installed in new boats— the Blue Water Seal. This is a proven system that is NZ MSA approved for use in commercial boats and is now used as standard equipment by well known boat builders.
The seal element can be easily removed should it be damaged or need replacing with no need to replace the entire unit as new seals elements are readily available from our spare parts department
The Blue Water Seal has a built-in safety feature to keep sea water out of the boat. If the seal element is damaged the seal retaining plate can be converted into a gland follower by placing a ring of greasy hemp gland packing under it to form an effective temporary seal allowing a replacement to be fitted at leisure.
These water cooled units are manufactured from cast admiralty bronze, chosen for its excellent bearing and salt water resistant properties. They are available for 25-76mm (1”- 3”) shaft diameters.

Complementing the more conventional shaft seals that are still widely used in the industry, Clements Marine principally recommend a complete range of non-metallic self-aligning shaft seals designed and produced by Tides Marine Inc in the U.S.A.
This innovative seal has become widely used recently in the UK leisure boat design by a number of the large builders. These seals have many performance enhancing characteristics but specifically their dripless and wear free performance over a guaranteed 2000 hour, or two year operating life. The components are manufactured using non-metallic composite materials which are dimensionally un-affected by temperature changes and will not become damaged by water absorbtion.

The Tides Marine Spare Seal Carrier Kit is used in conjunction with the Tides Marine SureSeal dripless propeller shaft system.
It provides a convenient way of storing a replacement lip seal on the propeller shaft during installation of the SureSeal.
This allows the change of a damaged or worn lip seal without uncoupling the shaft from the transmission.
If necessary the lip seal can be replaced with the craft afloat.

Tides Marine SureSeal is the market leader in dripless propeller shaft sealing systems. SureSeal has become an industry standard fit on many production-built power boats, yachts and commercial craft around the world.
The Tides Marine SureSeal system is a water tight, self aligning shaft seal housing connected to the stern tube by a flexible silicon hose.
Manufactured for imperial and metric shaft diameters of 1.375"/35mm to 8"/200mm with hose options to suit a wide range of stern tube diameters.
Tides Marine SureSeal has Ameican Bureau of Shipping and Lloyds Register Type Approval certification.
Suitable for new build and retrofit applications in all types of shaft drive vessels.

Seals have been developed to operate on propeller shafts of small, medium and large size boats where a high level of reliability is required.
The special design allows large axial displacement and the use of suitable material guarantees as well as high resistance to corrosion and high mechanical resistance to withstand stresses produced by vibrations.
The installation of mechanical seals in this particular field has solved problems such as corrosion during long periods of inactivity and shaft damage caused by traditional stuffing boxes. Power absorption is considerably reduced as well.

The use of face seals allows us to resolve the typical problems in which, over time, the installation of the traditional stuffing box incurs, that is wear on the shaft, wet bilge and continuous tightening of the packing, etc. Schematically, the face seal is made up of two parts: one that is stationary and one that rotates. The stationary part is generally fixed to the packing box; the rotating part is fixed to the shaft and turns with it. Thus there is no wear on the shaft: in fact the true seal is found perpendicular to the shaft in two micro lapped surfaces that rub against one another. The elastic bellows or springs recuperate eventual surface wear, thus the constant tightening of the packing is not required. Moreover, the presence of bellows and/or springs, in addition to recuperating wear, serves to compensate eventual misalignment, absorbing vibrations or sudden shifts of the shaft.

The Tides Marine SmartSeal temperature monitoring system has been developed for the Tides Marine SureSeal dripless propeller shaft seal.
Designed to monitor the temperature of the seal head and then provide an audible and visual alarm if an excessive rise in operating temperature occurs.
The system is suitable for 12v DC or 24v DC and can be retro-fitted to existing SureSeal units already installed.
