Budsen Electric Boat with a Tides Marine seriesOne Drip-Free Shaft Seal

Budsen Electric Boat

seriesOne Overview

The seriesOne™ shaft seal was designed for smaller, single-engine vessels with stainless steel propeller shafts. This shaft seal fits shaft diameters from 7/8” through 1 1/4” in 1/8” increments. It can also be used on metric stainless shafting from 25mm through 30mm. The seriesOne shaft seal is covered by a one year warranty. Tides Marine suggests that all twin-engine applications use the Tides SureSeal™.

HOUSING

The seriesOne housing is produced in the same manner as the SureSeal shaft seals. However, in order to produce a shaft seal for our more cost-conscious customers, the front cap design of the seriesOne has been modified.

As a result, the lip seal in the seriesOne is NOT replaceable.

When the lip seal in the seriesOne is worn to the point of leaking, the entire shaft seal housing must be replaced.

BEARING

The seriesOne bearing is machined from PTFE to precise tolerances.

HOSE

The seriesOne shaft seal is available with two hose options. For vessels like ski boats with shorter shafts (approximately 3’ in length), higher operating RPMs (3500 RPM+) and more rigid engine mounts, a single convolution articulating hose is recommended.

For vessels powered by smaller diesel engines (1-3 cylinders) using softer engine mounts, the multi-convolution articulating hose is recommended. This extra flexibility compensates for increased lateral engine movement during operation.

HOSE CLAMPS

IFour 316 SS clamps are provided with each seriesOne shaft seal.

Before Ordering

seriesOne shaft seals come complete with application-specific articulating hose and clamps. To determine which seriesOne to order, simply measure your propeller shaft OD as shown at A in the picture and write down the shaft size.

Next, measure the OD of your stern tube as shown at B in the picture and write down the stern tube size. Match these two measurements with the corresponding part number in the Imperial or Metric Sizes page.

Next, note the minimum distance as shown at C in the picture, associated with your part number in the minimum distance column in the Imperial or Metric sizes page. Confirm there is at least this much clean, smooth propeller shaft between the coupling and the stern tube on your vessel.

seriesOne Installation Guide

The following is a brief description of a typical seriesOne 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 seriesOne unit into the articulated hose and push in as far as it will go.
  6. Position the seriesOne 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 seriesOne. 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. 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”. Hose clamp screws should be on opposite sides to distribute the pressure evenly. Space the two clamps on the seriesOne end of the hose evenly and “snug”. Confirm that both the seriesOne shaft seal and stern tube are fully inserted into the articulating hose. Tighten all four 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 seriesOne 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.
  16. CHECK WATER SUPPLY TO SERIESONE BEFORE OPERATING VESSEL (1 gallon per minute at idle)
  17. *** NEVER USE GREASE OF ANY KIND ***
