2x E Ring 53-815949 for MerCruiser Alpha One Gen 2 Quicksilver 815949 18-2345 — Germany Local Warehouse
Product Overview
Sterndrive E ring, a retaining part for MerCruiser Alpha One Gen 2 and Quicksilver Alpha One drives built from 1991 to 2013, supplied as 2 x rings per pack, shipping weight 12 g. It replaces MerCruiser 53-815949 and 815949, and crosses to Sierra 18-2345. Shipped from our Germany local warehouse.
The ring sits in a groove on the shaft and holds the assembly where it belongs. It is a one-use part: once it has been levered out of the groove the legs are bent and it will not seat again, so a rebuild that reuses the old ring ends with a shaft that walks and a gearcase that comes apart a second time.
Nothing about the part is expensive, which is exactly why it is worth having on the shelf. It is also easy to lose over a bilge floor on a cold afternoon on the hard, and a rebuild cannot be closed up without it.

A Clip You Only Get One Chance At
| Point in the Rebuild | What Happens | What to Do |
|---|---|---|
| Levering the old ring off | Legs bend, ring will not reseat | Treat it as scrap, fit a new one |
| Groove in the shaft is worn round | New ring walks out on the first run | Inspect the groove before assembly |
| Ring dropped in the bilge | One pack of two is suddenly one short | Keep a spare pack on the shelf |
| Gripping the ring with pliers | Open end distorted by the jaws | Grip the flat side, not the open end |
| Closing the housing without a check | Ring not seated, shaft walks later | Confirm it sits in the groove and spins freely |
| Boat stored on the hard for the winter | Service done once, parts bought twice | Order the clip with the rest of the rebuild |
Fitting Notes
| Step | Action |
|---|---|
| 1 | Read the serial number on the transom plate and check it against the ranges above |
| 2 | Look at the old ring as it comes out, they deform as they are levered off the shaft |
| 3 | Check the groove in the shaft for wear, a rounded groove lets a new ring walk |
| 4 | Clean the groove before fitting |
| 5 | Fit the new ring with pliers that grip the flat side, not the open end |
| 6 | Confirm the ring is fully seated in the groove and spins freely before closing the housing |
| 7 | Keep the spare ring in the boat, they are easy to lose over a bilge floor |
| 8 | Check the assembly for movement after the first run |
