Carefully slide the assembly (hose end first) onto the shaft and onto the stern tube.
DO NOT USE GREASE!
Push the articulating hose over the stern tube as far as it will go. If you are using straightwall hose,
no more than two inches. Do not tighten clamps.
Evenly space the two hose clamps over the stern tube end of the hose. Stagger hose clamp drives
on either side of the hose to distribute pressure evenly. Make certain the drives are accessible.
Confirm that hose clamps fully engage the SureSeal™ and the stern tube. Tighten clamps.
Pull the red installation hat from the SureSeal™. Separate the tabs to split the cone and remove
it from the shaft. Retain hat for future use or contact Tides for replacements.
Connect the SureSeal™ to a pressurized water supply source (a point in the engine’s raw water
cooling system) by attaching the water injection hose to the stainless fitting on the SureSeal™
housing. If there is a second injection hose fitting on the SureSeal™, it is used to complete a
crossover feed between the port and starboard SureSeals™.
CHECK WATER SUPPLY FROM THE ENGINE TO THE SURESEAL™ BEFORE OPERATING
VESSEL.
There should be at least one gallon per minute flowing into the SureSeal™ at engine idle.
Reconnect the shaft to the coupling. Make certain the coupling is firmly secured to the transmission. Slide the SureSeal™
forward on the shaft until the hose is clear of the stern tube. Check to make certain the shaft is centered in the stern tube.
If it is not centered, it will be necessary to realign the running gear to achieve this end result. If the shaft is not centered in
the stern tube, side loads on the SureSeal™ will be created, dramatically reducing bearing/life performance. Then, carefully
slide the SureSeal™ assembly onto the stern tube, making sure the articulating hose does not “bend” in any direction.
CAUTION!
IN MOST SAILBOATS AND THOSE POWERBOATS WITH ENGINE(S) INSTALLED BELOW THE WATERLINE (OR WHERE WATER-LIFT
MUFFLERS ARE USED), A VENTED LOOP MAY BE REQUIRED TO PREVENT BACK FLOODING OF WATER THROUGH THE EXHAUST
SYSTEM INTO THE ENGINE. ABYC GUIDELINES REGARDING MATERIALS AND INSTALLATION PRACTICES SHOULD BE FOLLOWED.
The water pick-up fitting should be installed in the “pressure side” of the vented loop “T”. This vented loop should be as
far above the waterline as is practical (a minimum distance of 12" is required). In twin engine applications with water-lift
mufflers, a check valve in the water pick-up line is required if a crossover line is used.
