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.

Please note: If your propeller shaft is in poor condition with tool marks, rust or pits in the area where the seal will ride on the shaft, then the Tides SureSeal is not recommended. A "Face Seal" shaft seal would work better in this instance.
