21407250 Control Cable | Genuine Volvo Penta Part

🔧 Product Description

A premium low-friction Xact mechanical throttle and gear-shift cable, listed at 37 ft (11.28 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 3851071, 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

• Increasing effort needed at the control head to shift or open the throttle
• Shift going through neutral with a clunk, or hunting for engagement
• Slack that has to be taken up at the trunnion again a few hours after adjustment
• Chafe marks, flattened sections or a cut outer where the cable passes a bulkhead
• Threaded end fitting seized, bent or stripped when the adjustment is disturbed

🛠️ Service Notes

• Work the length out before ordering: shortest practical route from control mechanism to engine or transmission connection, plus a 200 mm radius at every bend, rounding up to the next listed length - a cable must not be shortened to suit
• An order placed under 3851071 resolves to this number
• The standard cable in the same 37 ft length is 21633508 - 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
• The cables must not be cut to size
• A single engine installation requires two cables and a twin installation requires four
