SureSeals are sold as a kit which includes a section of articulating hose (in most instances) and four hose clamps.

To determine:

1) If you have enough space to install a SureSeal and
2) Which SureSeal to order, you must know the following measurements:

  • Without a Spare Seal Carrier Kit

    1. Shaft Diameter
    2. What the Stern Tube Outside Diameter: (OD of your Stern Tube)
    3. Minimum Distance required from the End of the Stern Tube to the Coupler: (See Imperial/Metric Sizes Chart)
    4. Overall Height of the SureSeal Housing
    5. Distance from the End of the Stern Tube to where the Lip Seal will ride on the shaft
    No Spare Seal Carrier
  • With a Spare Seal Carrier Kit

    1. Shaft Diameter
    2. What the Stern Tube Outside Diameter: (OD of your Stern Tube)
    3. Minimum Distance required from the End of the Stern Tube to the Coupler: (See Imperial/Metric Sizes Chart)
    4. Overall Height of the SureSeal Housing
    5. Distance from the End of the Stern Tube to where the Lip Seal will ride on the shaft

Verify that the dimensions listed in the chart will fit your application. (Optimally you should have 3/4 inch to either side of dimension E of pristine shaft condition)
Use our SureSeal Locator or the Imperial or Metric Size charts to determine your part number.

A hose running from a point on the engine's raw water cooling system to this single injection fitting that will deliver cooling/lubricating water to the SureSeal. This water supply should produce a minimum of 1 gallon per minute at idle speed and approximately 2 psi. It should increase as you throttle up.

Warning! *** The SureSeal is not recommended for engines with less than 4 cylinders ***


Tides Marine offers a water pick-up kit to complete your installation.

CAUTION: The turn of the Exhaust Riser MUST be ABOVE the rest of the Exhaust System
Before operating the vessel you MUST TEST the Water Supply

Waterline

Other Important Installation Notes

A. Vented Loops

When the engine(s) is/are installed below the waterline (or water-lift mufflers are used), a vented loop may be required to prevent back-flooding of water through the exhaust system and into the engine.

Follow ABYC guidelines regarding materials and installation practices. The vented loop or siphon break should be checked for proper function annually at a minimum.

The water pick-up fitting should be installed on the “pressure”  side of the vented loop “T”. This vented loop should be as far above the waterline as is practical (a minimum of 12″ is required).

B. Check Valves

In twin-engine installations with water-lift mufflers, a check valve in each of the water pick-up lines is required if a crossover line is used between two SureSeals. The check valves should be checked for proper function annually at a minimum.

Maintenance

A. Tides Marine SureSeals require no winterization. Winterization fluids will not harm the SureSeals.

B. SureSeal assemblies should be inspected at least annually.

i. Inspect the blue articulating hose for damage.

ii. Inspect the hose clamps for corrosion.

iii. Remove the water injection hoses from each SureSeal and make sure the fittings and hoses are free of debris.

iv. It is very important to regularly check the pick-up point and water flow in the engine’s raw water cooling system. The water flow should be checked anytime the vessel has run hot or been aground.

If this fitting is a hose barb, Tides recommends that you remove the fitting from the pick-up point. Make sure it is free of debris, corrosion, etc. It is also a good idea to inspect the pick-up point for any debris that may have collected since the last inspection.

If your water pick-up system uses hose tees, you should not have to remove the tee. Simply check the branch fitting on the tee to make sure it is free of debris.

v. If your water pick-up system has any shut-off valves, check valves, siphon breaks or sight-gauges, be sure to inspect these as well.

vi. Make sure all hoses and clamps are re-assembled securely once you have completed any regularly scheduled inspections.
