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. Please contact us for advice at 800-420-0949.

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.

Tides Marine sells Water Pick-Up Kits that are required by any drip-free shaft seal.

SureSeal shaft seals may be ordered online.

Before Ordering

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. Stern tube outside diameter (OD of your stern tube).
  3. Minimum distance required from the end of the stern tube to the coupling (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, generally between 4 to 7 inches ahead of the stern tube.

 

With a Spare Seal Carrier Kit
  1. Shaft diameter.
  2. Stern tube outside diameter (OD of your stern tube).
  3. Add 1 inch to the minimum distance required from the end of the stern tube to the coupling (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, 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. Please contact us for advice at 800-420-0949.

Use our SureSeal Identifier or the Imperial or Metric size charts to determine your part number.
Verify that the dimensions listed in the chart will fit your application. (Optimally you should have pristine shaft conditions in the area 4 to 6 inches from the end of the stern tube towards the coupling!)

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.

 

 

Recommended Water Pick-Up Points in Order of Preference
  1. Hose Tee: In-line between the heat exchanger and riser (as close to the heat exchanger as possible).
  2. Hose Tee: In-line between the oil cooler and the heat exchanger.
  3. Hose Tee: In-line between the water pump and the oil cooler.
  4. Drain Plug: Hose barb in the heat exchanger.
  5. Drain Plug: Hose barb in oil cooler (if oil cooler is on pressure side of water pump). The bore should be at least .200”.
  6. Drain Plug: Hose barb in the back of the water pump. Be sure the drain is on the pressure side of the pump.

 

 

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
  1. Tides Marine SureSeals require no winterization. Winterization fluids will not harm the SureSeals.
  2. SureSeal assemblies should be inspected at least annually.
    1. Inspect the blue articulating hose for damage.
    2. Inspect the hose clamps for corrosion.
    3. Remove the water injection hoses from each SureSeal and make sure the fittings and hoses are free of debris.
    4. 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.

    5. 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.
    6. Make sure all hoses and clamps are re-assembled securely once you have completed any regularly scheduled inspections.

SureSeal Identifier

The SureSeal Identifier is used to find the SureSeal Part Number that is right for your boat. Simply enter:

1. Your propeller shaft type, Imperial or Metric.
A. Your propeller shaft diameter.
B. Your stern tube OD (Outside Diameter)
C. If you have twin engines, do you plan on using the recommended crossover line?
D. You have the minimum required distance from the Coupling to the Stern Tube. See Charts: Imperial or Metric

Note: The propeller shaft must be in pristine condition in the area from 4 to 7 inches from the end of the stern tube towards the coupling!

Once you enter Yes or No for the crossover line, you will be directed to our online store to purchase the SureSeal. Once in the store, you will again have to choose the stern tube OD and which water injection fittings you require.

If you choose not to use this tool, you have the option of going to the Imperial or Metric Sizes chart on this website located in the sub-menu above.

SureSeal Installation Guide

The following is a brief description of a typical SureSeal installation. Detailed instructions are included with each product and should be followed closely.

 

 

  1. Remove shaft from transmission coupling.
  2. Disassemble and remove all of the existing shaft sealing system.
  3. Remove the hose clamps and old hose from the shaft log (stern tube). Discard them. DO NOT RE-USE these components as they will not function correctly with the SureSeal.
  4. Draw the shaft back up against the coupling. This will expose the portion of the shaft that was located under the old hose and stuffing box.
  5. Insert the end of the SureSeal unit into the articulated hose and push in as far as it will go.
  6. Position the SureSeal Unit while installed in the articulated hose next to the stern tube to determine approximately where the lip seal will ride on the shaft.
  7. Examine this area carefully. Be SURE that it is free of pitting, nicks or surface imperfections which could cause leaking. Clean this area thoroughly. Polish the shaft using 280 to 320 grit wet/dry sandpaper or emery cloth working around the shaft. Fore and aft actions could put flats or grooves in the shaft. Do NOT over polish the shaft or this will prevent the lip seal from sealing out the water. The assembly may be shifted forward slightly by adjusting the position of the hose on the stern tube at the time of installation.
  8. Carefully press the red seal protector into the front of the SureSeal. Make certain it covers the “lip” portion of the seal.
  9. Back the shaft away from the coupling to provide enough room to install the assembly.
  10. Carefully slide the assembly (hose-end first) onto the shaft so that the shaft passes through the red seal protector.
  11. Slide the assembly down the shaft and onto the stern tube. Push on as far as it will go or as needed to position the lip seal on a clean spot on the shaft. Make sure the hose is over the stern tube enough to be able to put both hose clamps on.
  12. Reconnect the shaft to the coupling. Make certain the coupling is firmly secured to the transmission.
  13. Space the 2 hose clamps over the stern tube end evenly and “snug”. Hose clamp screws should be on opposite sides to distribute the pressure evenly. Space the two clamps on the SureSeal end of the hose evenly and “snug”. Confirm that both the SureSeal and stern tube are fully inserted into the articulating hose. Tighten all hose clamps.
  14. Pull the red seal protector from the SureSeal. Separate the tabs to split the cone and remove it from the shaft.
  15. Connect the SureSeal to a pressurized water supply source (point in the engines raw water cooling system) by attaching the water injection hose to the stainless steel fitting on the housing. If there is a sceond hose fiting on the SureSeal, it is used to complete a crossover feed between port and starboard shaft seals. Complete crossover instructions are included with the Water Pick-Up Kits and should be followed closely.
    CHECK WATER SUPPLY TO SURESEAL(S) BEFORE OPERATING VESSEL (1 gallon per minute at idle)
  16. *** NEVER USE GREASE OF ANY KIND ***

Imperial Sizes (All Dimensions are in Inches)

The chart below will give you the SureSeal part number and a link to buy the complete SureSeal Kit, the SureSeal Housing—which comes with a new lip seal and the water injection fitting(s)—the lip seal, connecting hose and hose clamps used in the SureSeal Kit from our online store.

All measurements are in 4 digit decimal form. For example, 7/8 inch = 0875, 2 inch = 2000, 2 5/8 inch = 2625.
(Note: Some SureSeal Kits use 2 different clamp sizes.)

Distance from the end of the stern tube to where the lip seal will ride on the shaft.

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 the propeller shaft surface anywhere between 4-7 inches ahead of the stern tube, 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 shaft condition is suspect (as described above) and hose adjustments cannot position the lip seal to a clean, “nominal” spot on the shaft, (while maintaining a 2 clamp engagement on both ends), or some sort of Face Seal product may work better on your vessel than the Tides product.

Metric Sizes (All Dimensions are in Millimeters)

The chart below will give you the SureSeal part number and a link to buy the complete SureSeal Kit, the SureSeal Housing—which comes with a new lip seal and the water injection fitting(s)—the lip seal, connecting hose and hose clamps used in the SureSeal Kit from our online store.

All measurements are in millimeters.
(Note: Some SureSeal Kits use 2 different clamp sizes.)

Distance from the end of the stern tube to where the lip seal will ride on the shaft.

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 the propeller shaft surface anywhere between 102MM to 178MM ahead of the stern tube, 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 shaft condition is suspect (as described above) and hose adjustments cannot position the lip seal to a clean, “nominal” spot on the shaft, (while maintaining a 2 clamp engagement on both ends), or some sort of Face Seal product may work better on your vessel than the Tides product.

SureSeal Shaft Seal Parts

The SureSeal Shaft Seal Housing has several parts that can be replaced. The best way to identify the correct parts is to give Tides Marine your six digit serial number from the side of the shaft seal or enter your six digit serial number in our serial number lookup form.

Those parts are:

  • Screws
  • Cap
  • Washer
  • Lip Seal
  • Injection Fitting
  • Collar

* It is recommended that if you replace the CAP or Collar you should also replace both the Cap and Collar.

Pentagonal Cap and Collar

Round Cap and Collar

SureSeal Lip Seal Change Video

In the video below you will see how easy it is to change the lip seal in a Tides Marine SureSeal drip-free shaft seal with Spare Seal Carrier Kit, while the vessel is in the water. With a Spare Seal Carrier Kit installed in front of the SureSeal, there is no need to break the coupler or haul the vessel out of the water.

 

SURESEAL vs STRONG SEAL

The SureSeal drip-free propeller shaft seal is the model currently offered by Tides Marine. It replaced the StrongSeal in the year 2000.

The StrongSeal has a stainless steel band around the front of the housing to maintain the lip seal dimensions. The lip seal is held in place by a retaining ring.

The current SureSeal model has 5 or 6 Phillips-head screws (depending on propeller shaft size) in the face with a removable cap and split washer. Some of the caps and collars are pentagonal and some are round. There is no difference between the pentagonal and round caps other than their shape. The lip seal has a recess all around it to make removal of the lip seal easy using only a small flat-bladed screwdriver.
