Master Throttle Cable 3/12 mm, Medium – code: 3714538 – Motomarine

Master rope jammer 3/12 mm Medium Motomarine (code 3714538)

The Master sheet jammer Motomarine in version Medium is a component dedicated to the management and locking of sheets in sailing. Designed for neat installation on deck or in the cockpit, it allows organizing running rigging and keeping the sheet in position during adjustments, with a practical setup suitable for routine maintenance of onboard equipment.

Main features and details

The rope jammer is identified as Master and Medium, with usage indication on sheets in the range reported by the manufacturer. The dimensions and mounting data below are useful to compare space and drilling with the installation area.

Available data (from product specification)

• Sheet: mm 3<12
• H: mm 27
• Screw spacing: mm 38 (M5)
• Working load: Kg 150

Codes and identification

• Brand / supplier: Motomarine S.R.L.
• Supplier product code: 3714538
• SKU: MOTO00000023

Typical applications

A rope jammer is normally used for lock and release a sheet in a controlled manner during adjustments. In the nautical field, it can be used in different positions, depending on the boat's trim and the arrangement of the lines.

• Sheet adjustment on running rigging on deck or in the cockpit.
• Line organization near winches, fairleads, and control points.
• Replacement of a worn sheet jammer, checking screw spacing and sheet range.
• Outfitting and refit where a dedicated locking point is needed for a sheet within the indicated range.

For a correct choice, it is good practice to compare the diameter of the sheet used and the available space, as well as to verify that the screw spacing and screws (M5) are consistent with the mounting base.

Advantages in use

This sheet jammer offers some typical advantages of the category, useful in the daily management of lines:

• Neater sheet management thanks to a dedicated locking point.
• Verifiable installation through declared dimensions (H and screw spacing), useful for replacements and retrofits.
• Dimensional compatibility with sheets in the indicated range (mm 3<12), for a more targeted choice.
• Clear reference through Motomarine code 3714538, useful for reordering and spare parts management.

The data of working load reported on the datasheet (Kg 150) is a useful reference for comparisons between similar products; however, it remains important to size the system as a whole (sheets, fairleads, fastenings, and supports) based on the actual setup.

Usage and installation notes

To achieve a clean and functional installation, it is advisable to plan the position of the sheet jammer so that the sheet works with a path as linear as possible and without interference with other lines. During replacement, verify that:

• the diameter of the sheet it falls within the range mm 3<12;
• the mounting area allows for height clearance (H mm 27);
• the drilling is consistent with spacing mm 38 and screws M5;
• the support surface is adequate and in good condition (no cracks, delaminations, or play).

For routine maintenance, periodically check the general condition of the component and the tightening of the screws, especially after the first outings or after interventions on the deck equipment.
