21407251 Control Cable | Genuine Volvo Penta Part

🔧 Product Description

A premium low-friction Xact mechanical throttle and gear-shift cable, listed at 38 ft (11.58 m). The Xact range is built for the smoothest and easiest throttle and shift operation with the least lost motion: the all stainless steel armoured strand core stays flexible enough to be taken round the tighter bends a difficult routing forces on it, and every fitting is stainless steel or plated brass. It supersedes 3851072, catalogued earlier as a control cable.

🔌 Function

Carries movement from the helm control head to the engine's throttle lever or the reversing gear's shift lever, pushing and pulling a sliding inner wire inside a fixed outer conduit so that the lever position you set is reproduced at the engine end.

⚠️ Common Signs of Failure

• Throttle or shift lever feels heavy and notchy where it used to move smoothly
• Gear will not engage fully, or the throttle does not drop cleanly back to idle
• Lost travel at the lever before the engine or gearbox answers it
• Outer conduit kinked, chafed or split, with rust weeping from an end fitting
• Inner wire found dry, corroded or seized in the conduit once it is withdrawn

🛠️ Service Notes

• Measure the run in as straight a line as you can from the control mechanism to the engine or transmission connection, allow a 200 mm radius for every bend, and take the longer cable if the figure falls between two listed lengths - the cables must not be cut to size
• An order placed under 3851072 resolves to this number
• The standard cable in the same 38 ft length is 21633509 - check which range the control head and engine bracket were set up for before moving between the two
• Select the exact cable length: fewer bends mean better operation and durability
• Measure in as straight a line as possible between the control mechanism and the engine or transmission connection, and allow a radius of 200 mm for every bend, so length = A + B + 200 mm
• If the measurement falls between two standard lengths, select the longer cable
• A single engine installation requires two cables and a twin installation requires four
