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 ***
