Compatibility / Fitment Guide
Measure the finished panel opening, cable bundle and mounting arrangement. A “50 mm hole” does not guarantee fit if the panel is too thick, the cable bundle is too large or the original ring/flange differs.
| Aperture | Requires a clean nominal 50 mm hole. Deburr and seal exposed laminate, plywood or metal before fitting. |
| Cable bundle | Check the cone’s small-end opening against the steering cable jacket plus any control/electrical cables passing through. Cables must move without crushing or cutting the rubber. |
| Panel retention | No ring is supplied. Reuse a compatible existing ring only if its diameter, screw pattern and clamping profile match; otherwise provide a suitable non-corroding retention method. |
| Routing | Maintain the steering-cable minimum bend radius and allow full outboard tilt/steering travel. The grommet must not carry cable load. |
| Not suitable for | Below-waterline penetrations, exhaust/fuel hose pass-throughs, pressure sealing, or any opening requiring a certified watertight gland. |

Frequently Asked Questions
Is it waterproof?
No. It is a flexible splash/chafe grommet, not a watertight hull gland.
Does it include the ring?
No.
Will it fit two cables?
Only if their combined diameter passes through without restricting movement; measure the actual bundle.
Can I fit it below the waterline?
No. Use an approved watertight fitting for that location.
Inspect the cone regularly for UV cracking, tearing and cable chafe, particularly where the outboard moves through full steering and tilt travel.
