Maintaining your Tides Marine Sure Seal® is a basic component of standard boating responsibility. This simple, easy to follow procedure will keep your bilges dry and your products functioning well for years, and should take no more than a few minutes, every few months.

    First, a visual inspection of the shaft seal is a good idea. Look for obvious signs of water leaking. A clean white cloth beneath the seal will identify any sediment from a poorly seated seal. If water is leaking, the spare seal carrier mounted on the shaft (if so equipped) contains the simple solution. Follow the procedure printed in your owner's literature and replace the worn seal. Be sure to arrange a replacement seal during your next haul-out to be returned to your carrier for future use.

    Second, water flow is key to longevity for shaft seals. With engines running and in neutral, remove the water feed line, cap the seal fitting, and capture the flow in a bucket or jug. Flow should be about 1 gallon per minute at engine idle. Increase your throttle to insure flow at all engine speeds, and repeat the procedure for the other engine, if applicable. Dress hose and secure. Complete one test before removing another line. Test cross over line as well, if so equipped.

    Finally, visually inspect your rudder bearings for signs of leakage. Depending on the style of rudder bearing installed, a spare seal carrier may be present here as well. While there is no water cooling source required, routine visual inspections should be part of your normal maintenance procedure. Consult your owner's manual.
