Self Aligning Shaft Seal

We've got some useful technical stuff here on how to sort out prop problems.

Product Overview

Designed for stainless steel propeller shafts for smaller boats, the seriesOne shaft seal by Tides Marine is available in 7/8”, 1”, 1 1/8” and 1 1/4” sizes. For metric applications, seriesOne is available in 25mm and 30mm sizes.

The seriesOne shaft seal is available for single engine applications only. For twin engines, the SureSeal™ is the product of choice.

Key components/features of the seriesOne shaft seal include:

Housing:

A one-piece body of complex composite material which allows the bearing surface to provide long life and a stable performance platform for the lip seal. The body material does not absorb water and is temperature resistant.

Bearing:

A unique structure in shaft body design has the body and bearing of the same material. From concept to reality, this design affords the boat owner a reliable, durable, component at the price of an “old fashioned” packing seal.

Hose:

Matched to various service demands, there are options which will add life to your seriesOne seal simply by identifying the application environment. For competition ski boats or other craft with short shafts, high RPM, and solid, tight engine mounts, the single convoluted hose is suggested. For work boats with softer engine mounts, small diesel engine applications such as on sailboats, or other shafts that exhibit more lateral movement during operation, the multi-articulated hose is recommended.

Hose Clamps:

Standard clamps, two per side as prescribed, will suffice. Should your intended use be in an extremely harsh environment, an upgraded clamp style is available.

Seal Replacement:

The seriesOne is designed to be removed and replaced when the useable lifespan has been achieved. If in-water replacement is a desired option, please use our SureSeal™ line of self aligning shaft seals. Spare seal carriers containing spare lip seals are available only for the SureSeal™ units.

Warranty:

Should your seriesOne shaft seal not perform to your expectations, contact Tides Marine for return authorisation within one year of purchase. Return the entire unit along with proof of purchase, to receive a replacement.

Before Ordering:

SeriesOne shaft seals are sold as COMPLETE kits which include: Seal, Articulated Hose, Seal Protector and Clamps.

Installation Overview: The following is a brief description of a typical seriesOne shaft seal installation. Detailed instructions are included with each product and should be followed closely.

• Remove shaft from transmission coupling.
• Disassemble and remove existing shaft sealing system if applicable.
• 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 seriesOne.
• Draw the shaft back up against the coupling. This will expose that portion of the shaft that was located under the old hose and stuffing box.
• Insert the end of the seriesOne unit into the articulated hose and push in as far as it will go.
• Position the hose next to the stern tube to determine approximately where the lip seal will ride on the shaft.
• 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 300 grit wet/dry sandpaper or emery cloth working around the shaft. Fore and aft actions could put flats or grooves in the shaft. The assembly may be shifted forward slightly by adjusting the position of the hose on the stern tube at the time of installation.
• Carefully press the seal protector into the front on the seriesOne unit. Make certain it covers the “lip” portion of the seal.
• Back the shaft away from the coupling to provide enough room to install the assembly.
• Carefully slide the assembly (hose-end first) onto the shaft so that the shaft passes through the seal protector.
• 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 sport. Make sure both clamps will go on.
• Reconnect the shaft to the coupling. Make certain the coupling is firmly secured to the transmission.
• To help align the unit, grasp the assembly and slide it forwards on the stern tube an inch or so and rotate it side to side twice. Slide the assembly back into position on the stern tube. Space the two hose clamps over the stern tube end evenly and “snug”. Confirm that both the seriesOnce shaft seal and stern tube are full inserted into the articulating hose. Tighten all four hose clamps.
• Pull the seal protector from the seriesOne shaft seal. Separate the tabs to split the cone and remove it from the shaft.
• Connect the seriesOne shaft seal to a pressurized water supply source (point in the engine's raw water cooling system) by attaching the water injection hose to the brass fitting on the housing. CHECK WATER SUPPLY BEFORE OPERATING VESSEL. At idle speed, water should be flowing 1 gal/4L per minute. Check rate by timing flow into an empty container.
