Luckily I heard this part drop (see pic attached) and retrieved it from just below the drive shaft at the transom. I haven't found a detailed diagram of this speedo adapter, so I don't know if it is a complete part, or if there are other pieces that need to be included. Without this part installed, seawater seeps into the bilge through a hole/fitting in the inner transom plate.
- Does this part just friction-fit into the hole in the inner transom plate (or maybe it is a fitting that aligns with a hole in the inner transom plate) without any solid connection like threads or adhesive? I did push it in by hand, but it seemed it could fall out easily.
- Does the spring need something on the end of it that acts like a stopper when no pressure is sent from the outdrive?
- Can I attach the speedo tube (that runs to the helm) to the white plastic stub?
- I did push the fitting in and attach the tube, which stopped the water from seeping in while moored in the harbor. But it seems quite fragile.
- Seems like I''m missing something because the black o-ring serves no purpose with my above descriptions.
