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
Key Features of the SureSeal include:
ABS and Lloyds Type Approval.
Minimal scheduled maintenance
Replaceable Lip Seal while in the water (with Spare Seal Carrier Installed).
No Winterization is necessary but winterization fluids will NOT harm the SureSeal.
Easy to Install.
HOUSING
Made from fiber-reinforced composite material, the housing is strong, durable and compact. The SureSeal® is dimensionally unaffected by temperature and will not absorb water.
BEARING
The integral PTFE bearing extends the operating life of the SureSeal® under normal operating conditions.
HOSE
Connecting the SureSeal® to the vessel is now easier with an “articulating hose”. This hose design automatically positions the SureSeal® the correct operating distance from the stern tube. No measurements are required – installation is simplified. The articulating hose reduces side loads to the SureSeal® when shaft misalignment occurs. As a result, lip seal and bearing life are extended.
LIP SEAL REPLACEMENT
The SureSeal® design incorporates a removable front cap which improves access to the lip seal. A worn lip seal can be replaced, even while the vessel is in the water, restoring the “100% watertight” characteristic of the SureSeal®.
INJECTION FITTING
The SureSeal water injection fitting is made from 316 stainless steel. Depending on the propeller shaft size, it comes in 3/8 or 1/2 inch sizes. A plastic cap is provided with each fitting so that if the injection hose has to be removed, the cap will restrict water flow into the vessel.
